Jumpers
There are three jumpers on the topside of the product, each labeled with its' function. At the bottom right of the
picture is a three way jumper labeled
I²C
that connects two pull-up resistors to the I C data lines. If you have
many devices on your I C data lines, then you may consider cutting these. Just above that jumper is the
JP2
jumper. If you cut this trace it will disconnect the
Power
LED just above the Qwiic connector. Finally, on the left
side of the product is the
JP1
jumper that when cut disconnects the
PPS
LED.
Chip Antenna
This GPS unit at the center of the PCB may look a bit funky to you. In fact you may be thinking, "Wow, that looks
suspiciously like a GNSS Antenna....". That's very astute dear hookup guide peruser. This GPS IC is actually built
into the antenna giving you an all-in-one GPS solution.
FTDI Header
At the top of the board, we have the traditional pinout for an FTDI header. Make sure that the FTDI that you use is
3.3V
and not 5V!
