Make sure these components are oriented like the image shows :) To rotate first left click then right click and rotate
if ordering from jlcpcb or pcbway the only component u need to get is promicro nrf52
these are not real world data but from my psu. idle is about 20mA transmitting is about 1.4A saw it almost reach 1.5A
readings can be off since its a Chinese psu 🤣
U need to flash the promicro with promicro diy Variant from the flasher. U might need to update the bootloader of the promicro to get it to accept the firmware.
