PCB pinout
External RC Receiver
For example an open R-XSR receiver set to PPM out and connected on the LED port of the flightcontroller board, no (mis) used for PPm input signals instead of LED board output.

GNSS
A Position sensor not (yet) added, could be a SAM M8Q or
Telemetry
A small ESP8266 based WiFi module is added.
Airframe file
Multiple targets in one airframe file: AP, FPV race, ACRO

Setup
Modification
The LED strip is removed and this pin makes room for a RC receiver. Reason to have a separate MCU for RC and not bog down the mail AP loop with build in SPI receiver messages.
Wifi
Solder T2 and R2 to the The GNDF and the VCC come from here

Manual
Flashing
USB cable
Uploading Paparazzi airborne autopilot software, also known a flashing is simple. New onboard software for the board can uploaded by connecting your PC via a micro-USB port to the autopilot board. For this the board needs to contain a bootloader. AFAWK all Trashcans come with a Betaflight already flashed on the board.
An alternative to get your firmware in the board is by using a Black Magic Probe JTAG/SWD debugger and programmer connected via the DWD pin. Not all to easy..
Serial Firmware Upload
Firmware upload using the factory integrated bootloader can be useful e.g. if you have overwritten the bootloader accidentally and don´t have access to JTAG. Either set the flash mode in the target section of the airframe configuration:
<configure name="FLASH_MODE" value="SERIAL"/>
or add it to the commandline invocation:
make AIRCRAFT=<aircraftname> ap.upload FLASH_MODE=SERIAL
