BeagleWire by Michael Welling is a fully open ICE40 FPGA BeagleBone cape:
BeagleWire is a completely open source FPGA development board. Unlike most other FPGA dev boards, the BeagleWire’s hardware, software, and FPGA toolchain are completely open source. The BeagleWire is a Beaglebone compatible cape leveraging the Lattice iCE40HX FPGA.
BeagleWire can be easily expanded by adding additional external modules for example, modules for high speed data acquisition, software defined radio, and advanced control applications. Using well-known connectors like Pmod and Grove makes it possible to connect various interesting external modules widely available in stores. Owing to this, prototyping new imaginative digital designs is easier.
Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with…

- FTDI USB interface – FT234XD-R
- RS485 interface – LTC2850IDD
- Buck converter – RT8010GQW
- SMA connector for antenna
OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:
Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.
We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!
thingSoC is an Open Source socket system for IoT development and has just launched a new Crowdy Supply campaign:
Build any IoT or Networked device you can imagine!
The thingSoC Grovey! platform gives you the freedom to choose from hundreds of existing sensors, actuators, and radios to quickly create new electronic systems, in plug together configurations that were not possible before. Easily mix together different CPUs, Radios, and Peripherals, like Servos, Motors, Relays, Sound and Lights, and then program them in your choice of Integrated Development Environments (IDE).
The thingSoC Grovey! series combines access to the Seeedstudio Grove system, and the Mikrobus “Click” system, to give you the widest selection of radios, sensors, and actuators available today.
The thingSoC Grovey Series files are available on GitHub:
You can now program the Open-V on the web, and see the results in real time. The code is compiled in the web IDE and then flashed to a microcontroller which is connected to a live YouTube live stream. It’s pretty neat to flash firmware on a microcontroller thousands of miles away and see the…
