How to get GPS data from the Flite Test EZ ID Remote ID Module into Betaflight
If you have a Flite Test EZ ID Module and want to use its GPS data for Betaflight's return to home feature or to have coordinates displayed in your OSD, here are the steps you need to take.
Step 1: Connect a signal wire from the EZ ID to your flight controller.
Connect the transmit pad (tx), which is the second from the left when looking at the underside of the board, to an open receive pad on your flight controller.
Step 2: Install a compatible version of Betaflight
Betaflight needs to be version 4.4.3 or newer to be compatible with the GPS data from the EZ ID. At the time this was written, 4.4.3 was not yet released. So to get this working you will need to install the development version of Betaflight called 4.4.3-zulu.
Step 3: Enable MSP on the correct UART
On the ports tab of Betaflight, enable MSP on the UART that you soldered the wire to and hit Save and Reboot. FYI, you can only have 3 ports configured for MSP. If you try to add a 4th, they will all disappear when you reboot.
Step 4: Enable GPS and select MSP
On the configuration tab in Betaflight, enable the GPS and change the protocol to MSP. Then save and reboot.
That should be it. Once the board reboots, you should see GPS information in Betaflight.
