MTCH2120

4.1 External MTCH2120 Evaluation

The following steps are required for connecting the on-board host MCU with an external MTCH2120:

Ensure the voltage of the external MTCH2120 does not exceed 3.3V, as the on-board host operates at 3.3V
Modify the PCB jumper by cutting the connection between J5 and J4, which is typically closed
Install Header J5 and connect it to the external MTCH2120 board
