The board will support various operating system including Android 7.1, Debian, Yocto Linux, and more. Some of the source code and software development tools are already available in github.

The board will be launched on the first of July, but price has not been announced yet due to the recent DRAM price hike. For reference, RK3328 TV boxes with 1GB RAM now sell for around $35 and the ones with 2GB RAM for around $45. Those prices include shipping and all accessories, and considering Pine64’s usually aggressive pricing, ROCK64 board may be sold for around $25 (1GB RAM), $35 (2GB RAM) and $45 to 50 (4GB RAM) excluding shipping. You’ll find a few more details, including PDF schematics and pinout diagrams, in the product page.

Update: I’ve just received my board, and updated the pictures above. I also came with a FORESEE eMMC module (see first picture), and a 5V/3A power supply.

Compulab’s Miniature “Bend & Fold” UCM-iMX7 System-on-Module Could Fit into a Watch

June 2nd, 2017 2 comments

Many companies are still releasing NXP – soon to be Qualcomm – i.MX 6/7 system-on-modules, but I don’t cover all of them, since we have already many to choose from. But Compulab’s latest UCM-iMX7 SoM differentiates itself by it size, using the company’s “Ultra-compact Multilevel Module” (UCMM) technology, to pack NXP i.MX7 processor, 2GB RAM, 64 GB eMMC flash, and a wireless module into a 30 x 27 x 8 mm volume that could potentially fit into something as small as a watch.

Click to Enlarge

The picture above clearly shows how UCMM technology works with the module comprised of two rigid PCBs and one flexible layer routing signals between the two allowing to bend and fold the rigid parts together to form a vertical stack. The principle could be extended to more PCBs and flexible layers, sof for example you could have four PCBs with three flexible layers in future / custom designs.

The rest of the specifications of UCM-iMX7 module are pretty standard:

  • SoC – NXP i.MX7 Dual or Solo with ARM Cortex-A7 core(s) @ up to 1GHz, ARM Cortex-M4 co-processor @ 200MHz
  • System Memory – Up to 2GB DDR3L-1066
  • Storage – Up to 64GB eMMC flash or up to 1GB SLC NAND flash, SPI flash for bootloader, EEPROM
  • Connectivity – Gigabit Ethernet PHY, WiFi 802.11b/g/n + Bluetooth 4.1 BLE via BCM4343W module
  • Audio – WM8731L audio codec
  • Other On-module ICs – SPI resistive touch controller, USB 2.0 hub, PF3000 PMIC
  • 2x 100-pin board-to-board connector with the following signals

    Block Diagram – Click to Enlarge

    • Display
      • Parallel 24-bit display interface up to 1920 x 1080
      • MIPI-DSI up to 1400 x 1050
      • Touchscreen 4-wire resistive touch-screen support
    • Camera
      • Parallel camera interface up to 24-bit
      • MIPI-CSI with 2 data lanes
      • Audio Audio codec with stereo line-out, line-in, mic
    • Networking – Gigabit Ethernet
    • PCI Express – PCIe x1 Gen. 2.1
    • USB – 1x USB2.0 OTG + 4x USB2.0 host ports
    • Up to 7x UART ports, up to 3x I2C, 3x SPI, 2x CAN, 6x Timer, 112x GPIO
    • Up to 4x general-purpose ADC inputs
    • Up to 2x MMC/SD/SDIO interface
  • Power Supply – 3.2V to 4.5V / Li-Ion battery
  • Dimensions – 30 x 27 x 8 mm
  • Temperature Range – -40 to 85°C

The specifications above are about the same as the ones for Compulab’s CL-SOM-iMX7 SO-DIMM module, but in a much smaller form factor, at the costs of a thicker design.

UCM-iMX7 module currently supports Linux kernel 4.1.15, Yocto Project file system, and U-Boot bootloader, with the company working on mainline Linux and upstream Yocto Project. The company expects the module to be used for autonomous drones, smart glasses, healthcare monitors / medical devices, industrial handhelds, and smart IoT cameras.

While the module is not directly aimed at the smartwatch market, the company demonstrated their module with a tiny smartwatch like gadget equipped with UCM-i>MX7, a lithium battery, a 1.5″ LCD display, and an interconnect board.

The board supports Microsoft Windows 10, Windows 10 IoT Core, Linux via Ubilinux, Ubuntu, and the Yocto Project, as well as Android 6.0 Marshmallow. The block diagram shown in March also included an extension HAT connected to the 100-pin docking port, but we did not have many details. With the launch on Kickstarter two stackable expansion boards are available:

  • Expansion board A [BRKH01] carrying high-speed signals: 1c2 channel PCI Express switch, Gigabit Ethernet (RTL8111G-CG / RJ45), HSIC/USB ports, uSIM card reader, SD card, etc…
  • Expansion board B [BRKL01] based on MAX10 CPLD exposing low-speed signals such as RS-232/422/484, I2C, I2S, and GPIOs, as well as 12 to 24V power input

The documentation to make your own UP Core expansion board will be made available, so more are likely coming, and up to three expansion boards can be stacked under UP Core board. The company will also pay royalties to makers of expansion boards that are selected (by UP community) to be sold on their store.

A chassis for UP Core and its carrier boards is also available in your prefer to keep the boards in an enclosure.

The company goal is to raise at least 10,000 Euros, but they should reach a much higher level once the campaign is completed. Some of the most interesting rewards are:

  • 69 Euros (early bird) then 75 Euros for UP Core with 1GB RAM, 16GB eMMC
  • 85 Euros (early bird) then 95 Euros for UP Core with 2GB RAM, 32GB eMMC
  • 119 Euros (early bird) then 129 Euros for UP core with 4GB RAM, 64GB eMMC
  • 125 Euros starter pack with UP Core with 2GB RAM, 32 GB eMMC, aluminum chassis, AC adapter, and WiFi+Bt antenna
  • 189 Euros dev.pack with UP Core with 4GB RAM, 64GB eMMC, A & B expansion boards, AC adapter, and WiFi+Bt antenna

They also have variations up to the 225 Euros super pack with comes with the 4GB/64GB board, the two expansion boards, three aluminum chassis, and accessories. Shipping adds 16 to 27 Euros depending on the destination country, and delivery is scheduled for August to October 2017 depending on the selected reward.

Top Programming Languages & Operating Systems for the Internet of Things

May 19th, 2017 3 comments

The Eclipse foundation has recently done its IoT Developer Survey answered by 713 developers, where they asked  IoT programming languages, cloud platforms, IoT operating systems, messaging protocols (MQTT, HTTP), IoT hardware architectures and more.  The results have now been published. So let’s have a look at some of the slides, especially with regards to programming languages and operating systems bearing in mind that IoT is a general terms that may apply to sensors, gateways and the cloud, so the survey correctly separated languages for different segments of the IoT ecosystem.

Click to Enlarge

C and C++ are still the preferred languages for constrained devices, and developers are normally using more than one language as the total is well over 100%.

Click to Enlarge

IoT gateways are more powerful and resourceful (memory/storage) hardware, so it’s no surprise higher level languages like Java and Python join C and C++, with Java being the most used language with 40.8% of respondents.

Click to Enlarge

When it comes to the cloud with virtually unlimited resources, and no need to interface with hardware in most cases, higher level languages like Java, JavaScript, Node.js, and Python take the lead.

Click to Enlarge

When it comes to operating systems in constrained IoT devices, Linux takes the lead with 44.1%, in front of bare metal (27.6%) and FreeRTOS (15.0 %). Windows is also there in fourth place probably with a mix of Windows IoT core, Windows Embedded, and WinCE.

Click to Enlarge

Linux is the king of IoT gateways with 66.9% of respondent using it far ahead of Windows in second place with 20.5%. They have no chart for the cloud, probably because users just don’t run their own Cloud servers, but relies on providers. They did ask specifically about the Linux distributions used for IoT projects, and the results are a bit surprising with Raspbian taking the lead with 45.5%, with Ubuntu Core following closely at 44.4%.

Click to Enlarge

Maybe Raspbian has been used during the prototyping phase or for evaluation, as most developers (84%) have been using cheap development boards like Arduino, BeagleBone or Raspberry Pi. 20% also claim to have deployed such boards in IoT solutions.

That’s only a few slides of the survey results, and you’ll find more details about Intel/ARM hardware share, messaging & industrial protocols, cloud solutions, wireless connectivity, and more in the slides below.

Wandboard QuadPLUS Development Board Gets i.MX 6QuadPlus Processor, 802.11ac WiFi and Bluetooth 4.1

April 16th, 2017 13 comments

The first Wandboard development boards launched in 2012 nearly 5 years ago based on Freescale i.MX6 Solo and Dual processor, with Wandboard Quad launched a few months later. The boards were fairly popular at the time due to their better specifications, and especially Freescale’s much better documentation and software compared to the competition such as Broadcom (Raspberry Pi) and Allwinner (Cubieboard). Since the boards are based on TechNexion EDM system-on-modules they could also be used by companies working on their own products based on the system-on-module. It’s also a good platform if you want to test various version of Android, because the company released Jelly Bean, Kitkat, Lollipop, and Marshmallow images for the boards, and I’m expecting a Lollipop version soon.

However, albeit the company worked on other NXP boards such as PICO-IM6UL Android Things, there had not been any hardware upgrade for Wandboard for nearly 4 years, but last month Wandboard QuadPLUS was released with NXP i.MX 6QuadPlus processor boasting a faster GC2000+ GPU, an upgrade to 802.11ac WiFi and Bluetooth 4.1 connectivity, the addition of a power management IC, and a fix for HDMI EDID + CEC.

  • Storage – 2x micro SD card slot + SATA connector
  • Video Output – HDMI with CEC
  • Audio I/O – HDMI, S/PDIF (optical), 3x 3.5mm jacks for Line In, Line Out, and Mic In.
  • Connectivity – Gigabit Ethernet (Atheros AR8035) + Wi-Fi 802.11 b/g/n/ac + Bluetooth 4.1 (Broadcom BCM4339)
  • USB – 1x USB 2.0 host port, + 1x mini USB OTG port
  • Debug – 1x RS232 port; UART & JTAG via through holes
  • Expansion Headers
    • 4x 20-pin headers with GPIO, I²C, PWM, SATA, SPI, UART…
    • 4-lane MIPI CSI connector
  • Power Supply – 5V DC via power barrel (5.5/2.1mm) ; NXP MMPF0100 PMIC
  • Dimensions – 95 mm x 95 mm
  • Weight – 100 grams

Beside Android, the board can also run Ubuntu, and Linux built with the Yocto Project. The company also introduced an official camera module for the board with CAM-OV5645 module based on Omnivision OV5645, and supported in Linux 4.1.15 and greater.

Wandboard QuadPLUS is sold for $139, CAM-OV5645 camera module for $25 directly on TechNexion website. The price of older boards have also been reduced by $10. You’ll find more details on Wandboard.org with firmware and source code downloads, a Wiki page, and forums, but most information has not been updated to include QuadPLUS board.
