5.4.2. JP2: Power LED (D4) and RS232 (U7) Transceiver Power

JP2 is used to connect the Vcc pin of the RS232 transceiver chip (U7) to the 3.3V supply of the board. It also connects the red Power LED (D4) to the board’s supply. It can be used to reduce the board’s power consumption by disconnecting the RS232 transceiver and Power LED. For normal operations, JP2 must be shorted.

JP2 is shorted by default.
