Miscellaneous PCB Works
The layout of this board took special consideration on soldering: All footprints with small pitches are arranged on the bottom side so they can be soldered easily with paste and heat guns or PTC heating tables. Components on the top side should be dealt afterwards.
Besides the pin headers, the sunk voltage is also supplied with a pad for connectors of 5.08mm pitches. On the right side, if the pad for external regulator is unused, it can also act as a 3.3V supply.
