Since Espressif launched the ESP32-Cx collection of RISC-V-based microcontrollers, they’ve been steadily growing in recognition and lifting the banner of RISC-V together with them. The ESP32-Sx collection isn’t going wherever, however should you’ve wished to hack on the brand new open structure, the OKD Bee and the OKD Nova are reasonably priced and simple to make use of!
Each boards have nice quick-start pages (like this one for the OKD Nova) that present you the best way to get began utilizing the Arduino IDE. The short begin guides additionally embrace wonderful high-resolution pictures with the board pinouts, in addition to details about the chip configuration, variety of GPIO, and so forth. The RISC-V processor is a part of an open structure, so you can even shortly get began utilizing open-source toolchains like MDK or Espressif’s personal ESP-IDF. The ESP32-C3 additionally helps utilizing PlatformIO, which integrates into VSCode and permits a full GUI debugging surroundings.
Word that each boards require exterior antennas; any 2.4GHz U.FL antenna will do. The good factor about having an exterior antenna connector is flexibility in antenna selection; you should buy an even bigger, high-gain antenna to get extra vary or get a tiny adhesive-backed versatile antenna to make use of inside a small enclosure. You possibly can even discover some enclosures on Tindie which have built-in U.FL to SMA connectors!
In the event you’ve ever wished to mess around with RISC-V and concurrently faucet into one of the vital cost-effective wi-fi microcontroller platforms round, these boards are a superb selection!
