My $6 ESP32-C3 (RISC-V) DevBoard

Yep, I made it myself, and it works!


And of course, a huge thanks to PCBWay for sponsoring this part of the project, it really helped.

Long story short, it works an absolute treat, with all the fun new features;

  • Onboard USB
  • 3.3V or 5V input
  • 2.54mm spaced debug pads
  • Improved keying slot
  • More GPIOs
  • Onboard optional status LED
  • Thinner PCB
  • Some silkscreen text fixed
  • Exposed track improved
  • BOOT and RESET buttons

And it was no effort to get it working with HomeAssistant via ESPHome, which I’ve shared the YAML for in GitHub. Here’s the link to the respository, and here’s the Hackster project too. If you want one, I’ve got them listed for cheap at my online shop since PCBWay sent me SO BLOODY MANY!

If you’ve got any input or ideas on what can be changed, I’m all ears. I’m already considering;

  1. Making my own ESP32-C3 module instead of using the MINI-1
  2. Changing to USB-C
  3. Adding another LDO for 12V input
  4. Changing to M.2 connector
  5. DW01 LiPo regulation
