Image of Board

A low-cost WiFi/BLE board based on ESP32-C3.

Features

  • Based on the ESP32-C3 WIFI & Bluetooth LE RISC-V Single-Core CPU
  • Type-C USB
  • Castellated pads
  • 4MB Flash
  • Clock speed: 160 Mhz
  • 15x Digital IO
  • ADC(5 channel, 12-bit), I2C, SPI, UARTx2
  • Size: 21mm x 51mm
  • Default firmware: LuatOS
  • 2 red status LEDs

Note

There are 2 versions of this board, differing in the inclusion of a CH343 UART to USB component. This board definition targets the version without the CH343 which connects the built-in USB-CDC/JTAG to the USB-C connector.

Onboard LDO can be disabled by grounding the PWB pin (15).

GPIO11 can only be used by setting the EFUSE_VDD_SPI_AS_GPIO efuse and building a custom Circuitpython image.

CircuitPython 8.0.0-beta.6

This is the latest unstable release of CircuitPython that will work with the Luatos Core ESP32C3.

Unstable builds have the latest features but are more likely to have critical bugs.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
