Overview
Transceiver is an open-source printed circuit board by someonelse20, from the someonelse20/Shadowfax repository on GitHub. It is a 4-layer board of 40 × 40 mm with 54 parts on 65 nets, routed with 338 tracks and 427 vias.
It is built around the MAX-M10S, ERTJ0ER104FM and MS621FE-FL11E. Its parts include 21 capacitors, 6 inductors, 5 resistors, 5 diodes and 4 connectors. It belongs with the radio and wireless boards and the STM32 boards of this library.
Main components
3README
README.mdShadowfax
FPV Drone designed from scrach. This design isn't fully custom yet but will get there eventually. I started this project to make a cool drone and learn as much as I can about engineering.
Flight Controller
The meat and potatios, the main computer for the drone.
Transceiver
A low frequency radio to communicate with a remote controller.
Camera Controller
Controls the camera and captures videos and pictures with a high frequency radio for faster communication.
Power Board
Powers the whole stack with 3.3v and connects the ESCs to the input voltage.
Frame
I made a custom frame to fit my custom boards and here it is.

Questions
How big is the Transceiver PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Transceiver use?
54 parts, built around the MAX-M10S, ERTJ0ER104FM and MS621FE-FL11E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Transceiver KiCad files?
From the someonelse20/Shadowfax repository on GitHub, at the commit this page was made from: the board is transceiver/hardware/transceiver.kicad_pcb and its schematic ESC/hardware/ESC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transceiver design in my own project?
Its repository states no licence, so its author keeps all rights: ask someonelse20 before reusing the design.
