Luatos Core ESP32C3
by Luatos
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.

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
