Release Types
The Kickstart Multi ROM board (board revision 3) is based on the Raspberry Pi RP2350 microcontroller and is mounted directly on top of the computer’s carrier board with a soldered castellated board. When it is connected via USB or to the computer, a red LED indicates power. It also has a green LED to indicate the firmware is running, and an orange LED to indicate the internal USB drive is mounted.
Installing or updating the firmware is as simple as copying the firmware file to the RP2350 USB drive. Please follow the Firmware installation guide.
