NanoPi Fire2A & Fire3 Boards Released with Samsung/Nexell Quad & Octa Core Processors

November 12th, 2017 26 comments

FriendlyElec previously launched NanoPi 2 Fire board powered by Samsung (Nexell) S5P4418 quad core Cortex A9 SoC, mostly interesting because of its small form factor, camera and LCD interfaces.

The company has now launched two new boards based on S5Pxx18 processors, namely NanoPi Fire2A powered by S5P4418 SoC, and NanoPi Fire3 based on S5P6818 octa-core Cortex-A53 SoC. Both boards share the same form factor, which remains quite similar to the one of NanoPi 2 Fire, except the HDMI connector now makes place for a micro HDMI port, the USB 2.0 has moved into vertical position, and a few other tweaks have been made to positions of buttons and components.

NanoPi Fire2A / Fire3 specifications:

  • SoC
    • Fire2A – Samsung S5P4418 quad core Cortex A9 processor @ up to 1.4GHz, Mali-400MP GPU
    • Fire3 – Samsung S5P6818 octa core Cortex A53 processor @ up to 1.4 GHz, Mali-400MP GPU
  • System Memory
    • Fire2A – 512MB DDR3
    • Fire3 – 1GB DDR3
  • Storage – 1x Micro SD Slot
  • Connectivity – Gigabit Ethernet port
  • Video Output / Display I/F- 1x micro HDMI 1.4a port up to 1080p60, RGB LCD interface
  • Camera – 24-pin DVP interface; 0.5mm pitch
  • USB – 1x USB Host port; 1x micro USB 2.0 OTG port for power and data
  • Expansions Headers – 40-pin Raspberry Pi compatible header with UART, I2C, SPI, GPIOs…
  • Debugging – 4-pin header for serial console
  • Misc – Power and reset buttons, power and system LEDs, RTC battery header
  • Power Supply – 5V/2A via micro USB port; STM32F03 ARM Cortex M0 MCU for power handling (SW power off, sleep , and wakeup function)
  • Dimension: 75 x 40 mm

Other differences with the earlier model: AXP288 PMIC is gone, and replaced by an STM32 Cortex M0 MCU, and the company has now added mounting holes for a heatsink. The company provides FriendlyCore, and Debian firmware images for both hardware, and an extra Android image for Fire3 board. FriendlyCore is based on Ubuntu Core 16.04 with Linux 4.4, Qt 5.9 with OpenGL, and GStreams with VPU acceleration. The good news is the Linux kernel got an upgrade from Linux 3.4 to a more recent Linux 4.4 LTS kernel.

You’ll find download links and instructions to get starting in the Wiki pages here and there. NanoPi Fire2A is sold for $28 plus shipping, while NanoPi Fire3 goes for $35. You may also be interested in compatible accessories and external modules, including S430 4.3″ capacitive touch screen LCD display, X710 7.1″ capacitive touch screen LCD display, HD101 10.1″ touchscreen LCD display, CAM500B 5MP CMOS camera, Matrix GPS module, and others which you can find by browsing in the store.

Giveaway Week – Nextion Enhanced 7″ Capacitive Display

November 4th, 2017 146 comments

My Nextion Enhanced NX8048K070 display will soon find a new home. The 7″ display comes with a capacitive touchscreen, an enclosure, and can work in standalone mode thanks to a built-in processor and a 8-pin FPC connector for I/Os, or connected to a micro-controller through a UART interface.

Click to Enlarge

I did a mini review of the display, mostly showing a teardown, and how to use Nextion Display Editor Windows-only tool to design your own user interface. The GPIOs are not really convenient to use with the required flat cable, and the company did not send me their $5 IO board, which would have made things easier. Learning curve may be a little sharper than needed as I’ve not found the Windows software to be very user-friendly, and documentation could be improved too.

Banana Pi M2 Magic Board Now Sold with Allwinner A33 Processor for $23

October 20th, 2017 14 comments

Banana Pi M2 Magic development board was first unveiled in February of this year with an Allwinner R16 SoC, 512 MB RAM, and 8GB eMMC flash, and its main selling points were support for MIPI DSI LCD displays, CSI cameras, and 3.7V LiPo batteries. AFAIK SinoVoIP never sold that version of the board, at least on Aliexpress.

Possibly due to the intricacies of Allwinner business units, the company has now officially launched Banana Pi M2 Magic (aka BPI M2M), but replaced Allwinner R16 by the similar Allwinner A33 processor, and removed the 8GB eMMC flash to bring the price down to $23 plus shipping. The “old” Allwinner R16 based Banana Pi M2 Magic board will apparently be sold as M2 Magic Plus soon.

Banana Pi BPI-M2 Magic (A33) specifications:

  • SoC – Allwinner A33 quad core ARM Cortex-A7 processor with ARM Mali 400 MP2 GPU
  • System Memory – 512MB DDR3
  • Storage – micro SD slot
  • Display Interface – 4-lane MIPI DSI connector
  • Camera Interface – CSI connector supporting up to 5MP sensor, 1080p30 H.265 video capture (OV5640 module)
  • Video Decoder – Multi-format FHD video decoding, including Mpeg1/2, Mpeg4, H.263, H.264, etc H.264 high profile [email protected]
  • Audio – On-board microphone
  • Connectivity – Wifi 802.11 b/g/n, Bluetooth 4.0 LE (AP6212) with u.FL antenna connector
  • USB – 1x USB 2.0 host, 1x micro USB 2.0 OTG port
  • Expansion – 40-pin header with GPIOs, UART, I2C, SPI, PWM…
  • Misc – Reset & power buttons, LEDs,
  • Power Supply
    • 5V/2A via DC power barrel
    • 3.7V Lithium battery support via 6-pin header
    • AXP223 PMIC
  • Dimensions – 51 x 51 mm
  • Weight – 40 grams

The Wiki indicates the board support Android and Linux, and provides some further information about the interface. Bear in mind SinoVoIP is often not quite fully correct, so make sure to double check if one of the feature is important to you.

[Update: October 30, 2017. M2 Magic with 8GB flash, Allwinner R16 sold for $28 + shipping]

2.9″ ESPaper Lite Kit is a $40 ePaper Display Kit with an ESP8266 WiFi Module

September 28th, 2017 8 comments

Squix (Daniel Eichhorn) has designed a 2.9″ ESPaper Lite Kite is a battery powered kit based on a black and white ePaper module, and ESP-WROOM-02 module based on Espressif Systems ESP8266 WiSoC.

Click to Enlarge

2.9″ ESPaper Lite Kit specifications:

  • Wireless Module – ESP-WROOM-02 WiFi module with Espressif ESP8266
  • Display – 2.9″ B&W ePaper module with 296×128 pixels resolution connect over SPI to ESP8266
  • Debugging / Programming – 6-pin serial port header
  • USB – 1x micro USB port for programming
  • Misc – 3 buttons: Reset (wake up from deep sleep);  S0 (flash/GPIO0); S1: user button connected to GPIO12; power switch; charging and (firmware) flashing LEDs
  • Power – JST connector for LiPo battery; charging circuit

You’ll need a 3.3V USB to TTL debug board for flashing the firmware to the board, and a LiPo battery to power it up. The solution is particularly useful if you want a battery powered display that is infrequently updated, since such display only consumes electricity when updated. They could run the module for several weeks with a 800m Ah battery while updating weather info every 20 minutes. MiniGrafx library provides drivers and samples for the board. It is available on Github.

The 2.9″ ESPaper Lite kit can be purchased for $39.90, but if you want something easier to get started you may want to get the 2.9″ ESPaper Plus Kit instead for $49.90, as it adds a USB to serial converter, a 600 mAh battery, an enclosure, and a USB cable.

7″ LCD Display with HDMI input, Audio output Launched for Orange Pi (and Other) Boards

September 15th, 2017 9 comments

If you want a cheap and simple way to add a screen to your development board, there are some 7″ displays with HDMI inputs that costs under $30 shipped. But Shenzhen Xunlong has decided to make their own 7″ LCD display with HDMI input and audio output, and sell for $22 + shipping.

The company only provided minimal technical information about the board and display:

  • Display  – 7″ TFT LCD with 1024×600  resolution
  • Video & Audio Input – HDMI
  • Audio Output – 3.5mm audio jack
  • Power Supply – 5V via micro USB port

If we look at a closer picture of the board, we’ll see they used Lontium LT8619B, but the company’s website is down… The board also features three different connectors for displays, so they probably have other displays planned. While the company claims the display is made for  Orange Pi H3 boards, it should really work with any board that can output 1024×600 over HDMI.

All you need to use the kit is a board, a HDMI cable (preferably less than 1.5 meters), and a USB power supply for the “transfer” board and the display. It should also be possible to connect speakers via the 3.5mm audio jack. As usual, no documentation is provided, but I would not expect too many issues as long as the hardware works.

Manga Screen 2 is Smartphone Touchscreen Display with USB and HDMI Ports for Makers (Crowdfunding)

July 20th, 2017 6 comments

Most touchscreen displays aimed to be connected to a development board work through a display interface such as MIPI DSI or LCD RGB (and USB or I2C for touch support), and come with somewhat low resolution such as 800×480 which can be suitable for HMI applications. They also often don’t work with all boards due to the different interfaces used, and there’s no way to easily connect such small display to your computer. Taking those limitations into account, and since most boards and computers come with HDMI and USB ports, Elias Bakken and his team have added HDMI and USB ports to two smartphone displays, and Manga Screen 2 was born.

The two displays – made by Sharp – have the following hardware specifications:

Big (5.9”) Small (4.8”)
Resolution 1920×1080 1280×720
FPS (max) 60 57
Color mode 24-bit
PPI 376.2 307.9
Brightness 400 cd/m2 500 cd/m2
Contrast ratio 1000:1 800:1
Viewing angle 80 degrees
Power draw (max.) 600 mA 520 mA
Active area 129.6 x 72.9 mm 105.6 x 59.4 mm
Weight ~95 grams TBD
Outline size 150 x 82 mm TBD
Touch points 10

They added the electronics to convert HDMI signals to whatever interface the displays use, and a micro USB port for power and the touch screen interface. So those should pretty much be play and plug, and work with Raspberry Pi, ODROID, BeagleBone Black and other boards, as well as your computer, laptop, etc…
The project has launched on Kickstarter with the goal of raising 300,000 NOK (~$37,100 US). Rewards start at ~$83.5 US for the smaller 4.8″ screen, and ~$94 US for the 5.9″ screen. Those are early bird rewards, and retail price should be $99 for both displays? (Maybe a mistake on KS). Shipping adds 85 NOK ($10.5), and delivery is scheduled for October to the big screen, and December for the small one.

Potential projects include home automation interface, standalone Spotify player, pet food dispenser, 3D printer interface, and any project that may benefit from a ~5″ touchscreen display. The promo video demonstrates some of those applications.

Thanks to Nanik for the tip.

Diskio Pi 13.3″ Touch Panel Display Kit is Designed for Raspberry Pi and ODROID Boards (Crowdfunding)

June 27th, 2017 7 comments

If your project requires a touch panel, there are plenty of solutions for Raspberry Pi and ODROID boards, with Hardkernel even selling ODROID-VU8C fully integrated touch panel display. However, most display kits require you to make your own case, and feature smaller displays with lower resolution. One developer has however come up with Diskio Pi, a higher-end touch panel kit with a 13.3″ Full HD display that works with the most popular Raspberry Pi and ODROID boards.

Diskio Pi with Raspberry Pi 3 Running Pixel

Diskio Pi specifications:

  • Display –  13.3″ AUO TFT IPS display with 1920×1080 resolution connected via a 30-pin eDP connector ; 330 cd/m2 brightness; 85° viewing angles in all directions.
  • Touch panel – 10-point capacitive touch; G/G structure; USB 2.0 interface; ≥6H surface hardness.
  • Main board:
    • HDMI to eDP driver
    • Stereo sound amplifier
    • USB 2.0 hub with 3x ports:  2x external + 1x internal
    • Battery balance circuit (3S/3S2P)
    • Expansion – Various headers for prototyping (RJ45, USB…)
    • Misc – Left & right mouse buttons (home button, USB); circuit protection via fuses, diodes…
    • Power Supply – RJ45 POE+ (Power over Ethernet)
  • Rack board:
    • Connections with the board via cables: 4 x USB, 2 x Ethernet, 1 x Power, 1 x HDMI
    • Fan circuit with potentiometer (fan will be optional)
    • Speakers – 2x round 3W speakers
    • Power Supply – 5V 3A from main board
  • Power Supply – 15 or 18V AC/DC adapter with EU, UK or US plug
  • Battery  – Optional 6 cells LiPo 3.7V=11.1V, 8000mAh
  • Dimensions – 348 x 265 x 25 mm (Final dimensions may change slightly)
  • Weight – 1.8 kg (prototype)

Diskio Pi with ODROID-C2 Board

Diskio Pi is currently compatible with Raspberry Pi 2, Raspberry Pi 3, Raspberry Pi Zero (W), ODROID C1+, and ODROID C2, but later, a modified kit will offer support for ODROID XU4 and Intel Atom based UP board. You can run any operating system you’d like since HDMI is used for video output (and converted to eDP), and USB used for the touch panel. You’ll be able to use accessories like the official Raspberry Pi camera, and there’s even space to add extra boards or modules like an Arduino mini or sensors using the IO headers or the internal USB port. The kit could be use as a large (and thick) tablet, an home automation dashboard, a portable Linux computer, etc…

The project has just been launched on Kickstarter with the aim of raising at least 400,000 Euros, which may prove to be a challenge, but we’ll see. The “very early adopter pack” rewards requires a 350 Euros pledge for Diskio Pi with the power adapter, but no battery, nor a Raspberry Pi or ODROID board. The 45 Euros battery pack is optional is reserved “for users who don’t need the POE+ power”. Shipping adds 9 Euros to France, 16 Euros to most of Europe, and 36 Euros to the rest of the world, with delivery scheduled for February 2018. The person behind the project has 10-year experience as… an optician, but he’s been working on the prototype for 18 months, and Advansee will take care of the final embedded electronics design, while CD-Plast will handle the mechanical design, with both companies based in the west of France.
