Ships with CircuitPython pre-installed!

The TinyC6 ships with an early alpha version of CircuitPython that supports the ESP32-C6.

There is also Arduino support in the upcoming 3.0.0 version of the ESP32 Arduino Core (currently in alpha) and IDF support in release 5.1 and later.

Please Note: The ESP32-C6 doesn't have native USB - so in CircuitPython it will not present itself as a mass storage device like ESP32-S2 and ESP32-S3 devices do. To connect to the TinyC6 to access the Flash file system or for REPL access, you connect to it via the serial port like you do with an ESP32-C3 or original ESP32.

Adafruit recommend using thonny for CircuitPython development on boards that don't have native USB. Once installed, select CircuitPython from the interpreter list in options, and then select the serial port for your TinyC6.

If you need to re-flash CircuitPython back on to your TinyC6, for now the shipping version aims available from here, and you can flash it to your board any following these instructions:

• 1.Download the firmware
• 2 Put your board into download mode
• 3. Flash it with the following command, changing {PORT} to the correct port on your computer/OS:

esptool.py -p {PORT} --before=default_reset --after=no_reset write_flash 0x0000 cp_tinyc6_firmware_9_alpha_5.bin

If you plan to develop in the Arduino IDE, please ensure you have the latest alpha version of 3.0.0 (or later) installed via the board manager, using the Development release link via these instructions provided by Espressif. Please note that though ESP32-C6 support is included, the UMTinyC6 board definition will not be available until the next alpha or beta release. It was merged after alpha 2 was released.
