Hi,
I have tested to use the internal PIN to supply out from the schematic, but have no luck to power up the device, we like to use own power connector in a housing and not the barrel jacket.
Hi, the PWR pin is same function as power button but use for power the board.
@Developer100 There’s no extra power pin or pad except the DC jack. You may destory the board if connect the pwr pin to the power supply.
