Original instructions

This is the documentation of firmware 101

Firmware 101 is the last documented Spectral Micro release that is flashed with a programming adapter (release 104 adds one CAN message, Send_Voltage_Limit, and is otherwise the same). Releases from 105 on carry a bootloader and update over UART or CAN; the current version of this site, which the version selector in the header opens, describes them.

Spectral Micro is in beta stage; the docs and the firmware are under constant development.

You can buy a Spectral Micro starter kit or a single Spectral Micro driver in the Source Robotics shop.
