2.3.1 Power Consumption SOM-SMARC-MX93 module, like all SMARC modules, needs a carrier board for its normal working. All connections with the external world come through this carrier board, which also provides the required voltage to the board. Measurements of power consumption from VDD_IN power rail (5V ) that supplies the board are reported here for 3 different board factory configurations.
