Hi,

I recently bought a Pypilot Hat 0.50 from Sean's store, and I am having a hard time finding any documentation what the 4-pole terminal block is for. 
None of the schematics I find on https://pypilot.org/schematics/ seems to apply, and the only text on the PCB is A, B, Z and Y.
See pictures below.

Does anyone have any information?

You can see this; I'm adding a Chinese GPS and asked Sean.

See photo 2 in particular.

Good luck.

Ok, so this implies it is a NMEA 0183 terminal
And the pinout you indicate in your 2nd photo seems like a possible match for J3 in https://pypilot.org/schematics/pypilot_hat.pdf

Can you confirm?

It is indeed nmea. It has galavanic isolation and levels translated, so not exactly the same as that schematic.

It has to be enabled from the pypilot_hat web interface, where you can assign remote control keys. This port is not really used by most people.

Please post here if you have success!

Excellent, thank you!
