Detailed Description
Support for the Serpente board.
General information
The Serpente boards are low-cost development boards designed to be used with Adafruit’s CircuitPython.
Three versions of the board board exist, but they all the same except for the USB connector. The standard Serpente board contains a female USB Type-C connector, the Serpente Plug C contains a male USB Type-C connector, and the Serpente Plug uses the board itself as a Type-A USB plug.
If you are familiar with the Digispark boards, you may notice some similarities. This fact is of course not incidental, the Serpente boards are inspired by the Digispark, both in form-factor as well as use-cases. The Serpente boards are meant to be used as quick and dirty, yet flexible, prototyping tools.
Pinout
Flash the board
Use BOARD=serpente with the make command.
Example with micropython application:
RIOT will automatically trigger a reset to the bootloader, but this only works if RIOT is still running on the board. If your application has crashed or got erased, make flash will not be able to trigger a bootloader reset.
To manually enter the bootloader, quickly press the Reset button twice. You know you've successfully entered the bootloader when the LED begins flashing blue.
Sometimes flashing fails and the board gets stuck in the bootloader. In this case, just run make flash again when the device is not busy anymore.
Accessing STDIO via UART
STDIO of RIOT is directly available over the USB port.
