Qt for MCUs 1.1 Adds Support for more STM32 and NXP i.MX RT Boards, FreeRTOS

The first stable version of Qt for MCUs was released in August 2019 in order to bring Qt graphical toolkit to microcontrollers such as STMicro STM32F7,  Renesas RH850, or NXP i.MX RT1050.   Qt for MCUs would run bare metal on supported boards, and software engineers would develop graphical interface using QML and C++. Qt for MCUs 1.1 has just been released with the addition of more STM32 and i.MX RT boards, support for FreeRTOS real-time operating system, and more. Qt for MCUs 1.1 highlights: Five new supported boards:  NXP i.MX RT 1064 EVK, STM32 H750B-DK, STM32 F469i-disco, STM32 L4R9i-disco, and STM32 L4R9i-eval Asset management Optional PNG compressions for assets to lower storage footprint Option to read data directly from flash memory for lower RAM consumption, or copy to RAM for better performance, at the cost of higher RAM consumption. FreeRTOS support (technology preview) to run background tasks without blocking the […]

YARC Case Can House a Raspberry Pi Board with one HAT Expansion Board and Up to 3 Hard Drives (Crowdfunding)

There are plenty of enclosures for Raspberry Pi board and other compact x86 or Arm Linux SBCs, but many projects require expansion boards and it’s not always possible to use an off-the-shelf case. That’s with that in mind that Stefano Zorzi and other enthusiasts have created YARC (Yes, Another Raspberry Case), a hexagonal case that supports the most popular single board computers, even when an add-on board – such as a Raspberry Pi HAT – is attached to the board. There’s enough space for up to three 2.5″ hard drives. Those are the boards officially supported (tested?) with the case: Raspberry Pi B +, 2B, 3B, 3B +, 4B, A +, 3A + Hardkernel ODROID C1, C2 AAEON Up Board Asus Tinker board and Tinker board S Radxa Rock Pi 4 Orange Pi PC, Pi PC2, Pi PC Plus Basically any board with compatible mounting holes can be installed in […]

DragonBoard 845c Android (AOSP) Reference Board Supports Open Source Graphics, Mainline Kernel

Besides the obvious Google Pixel and Nexus devices supported by AOSP (Android Open Source Project), we previously covered some single board computers that were also officially supported by the project with Hikey and Hikey 960 Android reference boards. Linaro Consumer Group (LCG) has just written about Qualcomm Snapdragon 845 based Dragonboard 845c board. It has been now an official Android reference board for a few months now, and it is the first such board with an open-source graphics stack thanks to Freedreno graphics driver and mesa framework. Since no proprietary blobs are required, the board’s full functionality can also be upstreamed into the mainline kernel, and Linaro currently uses the board as a test target for validating the mainline kernel and stable updates. Here’s a reminder of the board’s hardware specifications: SoC – Qualcomm Snapdragon 845 with 8x custom 64-bit ARMv8 CPUs up to 2.8 GHz, Adreno 630 GPU with […]

Widora TINY200 Allwinner F1C200s ARM9 Development Board Supports DVP Camera, Up to 512MB SD NAND Flash

Widora TINY200 is a tiny ARM9 development board equipped with Allwinner F1C200s with a DVP camera interface compatible with OV2640 / 5640 sensor, an audio amplifier, and various storage options from a 16MB SPI flash to a  512MB SD NAND flash. I first heard about the processor when I wrote about Microchip SAM9X60 ARM9 SoC last month, and some people noted there were other fairly new ARM9 SoCs around such as Allwinner F1C200s that also includes 64MB RAM so you can run Linux without having to connect external memory chips. Widora TINY200 V2 specifications: SoC – Allwinner F1C200s ARM926EJS processor @ 400-600 MHz (Overclockable to 900 MHz) with 64MB DDR1 RAM Storage – 16MB SPI NOR flash or 128MB NAND flash and MicroSD card slot or 512MB SD NAND flash. Display I/F – 40-pin RGB FPC cable for resistive touch screens; additional 6-pin FPC cable for capacitive touch support Camera […]

NanoPi R2S Dual GbE IoT Board and Gateway Launched for $22 and Up

We first covered NanoPi R2S SBC back in mid-January 2020. Specifically designed for headless and IoT application the board features a Rockchip RK3328 processor combined with 1GB RAM, and contrary to most competing platforms on the market such as Orange Pi R1 or NanoPi R1S, R2S comes with two true Gigabit Ethernet ports. At the time, the board was not available for sale, but now FriendlyELEC has started to take orders for just $22.00, and adding a yellow case adds $3 to the total. This is around $5 extra compared to NanoPi R1S gateway which was expected with extra RAM (1GB) and true dual GbE connectivity. But in the age of COVID-19, nothing runs quite as smoothly as it used to and the company expects shipping delays: Because of the epidemic, postal services in a lot of countries get delayed. Customers who need orders urgently need to choose DHL. EU […]

Radiona ULX3S Open Source Hardware ECP5 FPGA Development Board Launched for $99 and Up (Crowdfunding)

Last summer, we wrote about Radiona ULX3S education board combining a Lattice Semi ECP5 FPGA with an Espressif Systems ESP32 WiFi & Bluetooth WiSoC. Designed for a digital logic course at the University of Zagreb, the board is open-source hardware with KiCAD hardware design files released on GitHub, and programmable with the Arduino IDE (FPGArduino) and ProjectTrellis open-source toolchain. At the time, there was only a version based on Lattice ECP5 85F with 84K LUT, but they’ve now made versions with cheaper variants of ECP5 FPGA and launched the board on Crowd Supply. Radiona ULX3S specifications: FPGA (one of the other) Lattice ECP5 LFE5U-85F-6BG381C with 84K LUT Lattice ECP5 LFE5U-45F-6BG381C with 44K LUT Lattice ECP5 LFE5U-12F-6BG381C with 12K LUT System Memory – 32MB SDRAM @ 166 MHz Storage – 4–16MB Quad-SPI Flash for FPGA config and user data storage; MicroSD slot Audio – 3.5 mm jack with 4 contacts (analog […]

CloverPI Clusters Up to 4 Raspberry Pi Boards (Crowdfunding)

We’ve seen Raspberry Pi cluster boards before, and most of them either use Raspberry Pi Zero boards or Raspberry Pi Compute Modules. Some examples include Turing Pi Clusterboard for up to 7 RPi CM3 modules, Cluster HAT board taking up to 4 Pi Zero board, and Mininodes Raspberry Pi 3 COM Carrier Board. But some other solutions like Bitscope rely instead on full-sized Raspberry Pi 2/3/4 Model B boards. Another such option is IPTerra CloverPI board allowing up to 4 Raspberry Pi or compatible boards with 40-pin header to be clustered into a single unit powered by one power supply and connected via a 5-port Gigabit Ethernet switch. CloverPI is shown above without RPi boards. The mainboard includes four 40-pin headers, four 6-pin Ethernet headers for SBC’s, as well as one Gigabit Ethernet port, and one power jack. There’s also a board/card fitted in the middle of the latest version […]
