Waveshare Launches an Affordable 7-Color e-Paper Display

Most e-paper displays are black or white with sometimes red or yellow color being added to the mix. But E-Ink has recently launched several color e-Paper display at prices that will not make it affordable to most projects. Waveshare has launched its fair share of e-Paper displays in the past, and now the company is coming with a relatively affordable 5.65″ color e-Paper display with seven different colors for $74.99 plus shipping. Main features and specifications: Display 5.65″ display (114.9 × 85.8mm) Resolution – 600 × 448 pixels Viewing angle – >170° ACeP (Advanced Color ePaper) 7-color with black, white, green, blue, red, yellow, and orange Greyscale – 2 levels Full refresh time – 15s Dot pitch – 0.1915 × 0.1915mm Host Interface – 3-wire SPI or 4-wire SPI Operating voltage – 3.3V/5V Power Consumption 50mW (typ.) during refresh Standby current – <0.01uA (almost none) Dimensions – Board – 138.5 […]

PolarFire SoC Icicle 64-bit RISC-V and FPGA Development Board Runs Linux or FreeBSD (Crowdfunding)

We got some more details about PolarFire RISC-V FPGA SoC late last year, and we were promised a Linux capable 64-bit RISC-V & FPGA development board with PolarFire SoC Icicle kit in Q3 of 2020. We are already in July 2020. So where is the board? Oh, look! It’s right here on Crowd Supply where it is offered for $499, and shipping is expected to start in mid-September. PolarFire SoC Icicle specifications: SoC FPGA – PolarFire SoC MPFS250T-FCVG484EES penta–core RISC-V CPU subsystem (1xRV64IMAC, 4xRV64GC) with 254K LE non-volatile fabric, 784 18 × 18 math blocks, secure boot, 4x 12.7 Gbps SERDES, FCVG484 package (19 × 19 mm, 0.8 mm pitch) System Memory – 2GB LPDDR4 x32 Storage – 1 GBit QSPI Flash, 8GB eMMC Flash or SD card slot (multiplexed) Video Output – HDMI 2.0 (removed from final board) Connectivity – 2x Gigabit Ethernet, Wi-Fi, and Bluetooth USB – 1x […]

ODYSSEY-X86J4105 Gemini Lake & Arduino SBC Review with Windows 10 Enterprise

I’ve recently received ODYSSEY-X86J4105 SBC with Re_Computer case, and we’ve had a look at the SBC hardware, installed some internal components like an M.2 SATA SSD, and play around Re_Computer case using Raspberry Pi 4, Beaglebone Green Wireless and Jetson Nano SBC, before assembling the Intel SBC into the enclosure. I’ve now taken the time to test the combo using the pre-installed Windows 10 Enterprise operating systems. ODYSSEY-X86J4105 is very much like any Intel Gemini Lake mini PC, but with the addition of Arduino and Raspberry Pi headers, so we’ll look at those as well. Connections and First Boot For the first boot, I connect USB mouse and keyboard, a HDMI cable to a 4K TV, an Ethernet cable, a USB 3.0 hard drive, and finally the power supply. I actually had a small problem during boot, but we’ll talk about it later as it’s really specific to my setup, […]

Sparkfun Launches the ZED-F9R GPS Dead Reckoning Raspberry Pi pHAT for Mobile Robots

The SparkFun ZED-F9R GPS pHAT module is targeted at single board computers like the Raspberry Pi, Jetson Nano, and other boards with the 2 x 20mm header form factor supporting the GPS RTK (Real-time kinematic) capable of centimeter-level accuracy. Dead Reckoning in robotics allows one to calculate one’s position by using a previously known location or landmarks. Dead Reckoning is an essential aspect of robot navigation, especially Autonomous vehicles like mobile robots or UAVs. For dead Reckoning to be realistic and minimize the position uncertainty, it usually requires the fusion of position estimation sources like Lidar, Radar, IMU, Odometry, GNSS, accelerometer, and some others. Sparkfun understands this and has launched the Dead Reckoning add-on module that can be used for applications in mobile robots, UAVs, and others. The Sparkfun ZED-F9R GPS pHAT is an exciting sensor fusion board (having been a fan of Extended Kalmar Filter) that provides accurate and […]

Raspberry Pi Compute Module 4 Coming Next Year with PCIe/NVMe Support

The Raspberry Pi 4 features a Broadcom BCM2711 processor with Cortex-A72/A53 cores that makes it competitive against other SBC’s based on Rockchip RK3399 or Amlogic S922X/A311D processors. The new processor also happens to have a PCIe interface, but it’s not exposed on the board since the interface is used by VIA VL805 PCIe USB 3.0 controller for the four USB 3.0 ports on the little computer. At the time, we expected the PCIe interface to be exposed in future Raspberry Pi boards or a Raspberry Pi Compute Module 4. But some people did not feel like waiting and instead hack the Raspberry Pi 4 SBC to access the PCIe interface. That hack is clearly not for everyone though… But based on a recent interview of Eben Upton with Tom’s Hardware we got pretty much confirmation that the Raspberry Pi Compute Module 4 will be coming next year, and expose PCIe […]

GloDroid Brings Android 10 OS to Raspberry Pi 4, Orange Pi SBC’s, PinePhone, and PineTab

The community of developers working on software for single board computers often prefer to focus on Linux support, as companies will often provide Android firmware images. But those Android OS images are often not maintained at all, so we’ve seen some projects like the past such as H3droid bringing a better Android OS to Allwinner H3 and H2+ boards and devices. The project is still using Android 4.4 KitKat and that’s getting old with some apps like the latest version of Kodi not working anymore. But a new project has just been brought to my attention with GloDroid leveraging AOSP to bring Android 10 to various Allwinner based boards and platforms, as well as Raspberry Pi 4B. List of supported Allwinner hardware: Allwinner H3 (32-bit) based – Orange Pi Plus 2 SBC, Orange Pi Plus 2E board, Orange Pi PC Allwinner H5 (64-bit) based – Orange Pi Prime, Orange Pi […]

Mythic Beasts, miniNodes Offer Raspberry Pi 4 Hosting Services

Mythic Beats is the company offering hosting services for the Raspberry Pi website, and following Eben Upton proposal they decided to host the website on eighteen Raspberry Pi 4 boards, fourteen of which used as LAMP (Linux, Apache, MySQL, PHP) servers, as well as two used as static servers with Apache, and the final two used as memory store using memcache. Two days before Raspberry Pi 4 8GB RAM launch, they tested the implementation with “normal” traffic (e.g. around one million visitors a day), and the day of the launch, tens of millions visitors came to the website, and it failed, but not because of a failure of the Raspberry Pi cluster, but instead due to a Cloudflare glitch. This is all explained in Raspberry Pi blog. This is all for internal use, but you could also get your own hosted Raspberry Pi 4 board, as Mythic Beast recently added […]

ODYSSEY-X86J4105 SBC Unboxing and Re_Computer Case Review

ODYSSEY-X86J4105 Re_Computer Case Review

Seeed Studio ODYSSEY-X86J4105 is an Intel Celeron J4105 Gemini Lake SBC that also happens to integrate an Arduino compatible Microchip SAMD21 Arm Cortex M0+ microcontroller that makes it suitable as an all-in-one Arduino platform. But it can do much more with 8GB RAM, an optional 64GB eMMC flash, HDMI & USB-C DisplayPort 4K video outputs, dual Gigabit Ethernet, and support for both SATA and NVMe storage. The board runs Windows 10 Enterprise by default (if you purchase the board with an eMMC flash), and supports Linux distributions as well. Seeed Studio sent me a review sample, so I’ll start by checking out the hardware first. ODYSSEY-X86J4105 Unboxing I received ODYSSEY-X86J4105864 with a built-in 64GB eMMC flash pre-loaded with Windows 10 Enterprise. Let’s have a quick look at the board with USB, Ethernet and video output ports previously described, as well as built-in dual-band Wi-Fi 5 & Bluetooth 5.0 module, and […]
