MALE PIN HEADERS
Place and solder the three Male Pin Headers over the silkscreen at “JP1”, “JP2” and “ICSP”.
Caution:
the 2x3 pin
header (“ICSP”) is soldered on the reverse side of the PCB to the components you have already soldered. It is the
shorter pins of each pin header that you are soldering.
JP102 is an expansion port that is not currently use. There is no need to solder pins here.
POWER CONNECTOR
Solder the power connector at “EPOWER”, ensuring the position is correct: it must be placed over the silkscreen
marking with the pins facing the edge of the PCB.
