Datasheet

GPS TX pin to the microcontroller RX pin and can be controlled to change its data output from the GPS RX pin. Logic

level is 3.3V for both.

The baud rate by default is 9600 baud, but you can configure the module to use different baud rate if desired

The GPS is wired directly to the Serial pins at the bottom right of the Feather. Note that on the ESP8266 Feather this

is used for bootloading so the GPS module is not recommended for use with the ESP8266! The other Feathers use

USB for bootloading, so the hardware Serial port is available.

If you need to connect to a different set of pins, you can cut the RX and TX jumpers on the bottom of the board

And then wire your desired pins to the RX and TX breakouts right next to the FIX LED

GPS Breakouts

The GPS module has some more pins you can use:

GPS Reset - you can use this to manually reset the GPS module if you set the baud rate to something inscrutable or

you just want to 'kick it'. Reset by pulling low. Note that pulling reset low does not put the GPS into a low power state,

you'll want to disable it instead (see EN). There's a jumper on the back if you want to connect the GPS reset to the

microcontroller reset line
