Page 11: Generally Applicable Rules
The USB cable should be connected to the USB interface of the breakout board first before being connected to the PC/Notebook. DO NOT connect the USB interface while externally powering the device from the +5V pin. This can damage the MicroMaster LT, the breakout board, or the PC/Notebook.

Page 15: Pin Assignment
The CAN bus of the Breakout Board has an integrated 120 Ω termination resistor. This resistor is fixed, so the board must be placed at an end of the connected CAN bus. MicroMaster LT Hardware Reference MMAU | 2024-01 3-15... -
Page 16: Connection Functions
A USB Type A - micro B Cable is required to connect to the USB interface for programming or monitoring. The USB interface provides power to the MicroMaster LT while plugged in. A USB port can also be added externally using GPIO 19 and 20’s USB D- and D+ functionality. This port can be used either for a USB 2.0 OTG interface or as a secondary programming/monitoring interface. -
Page 17: Buttons
The two push buttons on the Breakout, BOOT and RESET, are to be used when programming and monitoring the device. The RESET button behaves similarly to a power cycle event of the MicroMaster LT controller. If the RESET button is triggered, the loaded program will be restarted. -
Page 18: Programming Interface
An optional programming board can be used, which can be used to upload programs to a MicroMaster that is installed on a motherboard without its own USB-serial programming interface. Figure 3-9 The standalone programmer can be used to program a MicroMaster that is in-situ. MicroMaster LT Hardware Reference MMAU | 2024-01 3-18... -
