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.

{Here photo where to solder it}


A Position sensor can be added, could be a uBlox CAM M8Q


Can be added, could be a LIS3MDLTR or a nice BM1422AGMV-ZE2


A small ESP8266 based WiFi module is added.

Airframe file

Multiple targets in one airframe file: AP, FPV race, ACRO

openuas_eachine_trashcan.xml  (Coming soon to PPRZ master)



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.


Solder T2 and R2 to the The GNDF and the VCC come from here

Power conversion

XT30 Connector

Careful when replacing the connector. Add a capacitor else you can damage your flight-controller board.

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
