ANT Radio breakout board for Adafruit Feather development boards
D52M Feather Wing is an open-source printed circuit board by reeganm, from the reeganm/ANT-FeatherWing repository on GitHub, published under the MIT licence. It is a 2-layer board of 22.9 × 50.8 mm with 2 parts on 45 nets, routed with 78 tracks and 4 vias.
It belongs with the microcontroller boards and radio and wireless boards and the ESP32 boards of this library.
You can order this board using the gerber and BOM (sockets/pins not included in the BOM.) We ordered ours from Seeedstudio and they work fantastic.
This board is restricted to ASYNC mode with the ANT radio. This is to optimize the pin usage since the ANT radio is the SPI master and Arduino does not support being a SPI slave. There will be an additional breakout board published in which those interested in using SPI will have those pins broken out.
The board can use any generic ANT driver but we recommend ant-arduino but you will have to set all pins manually other than TX/RX. If you are looking for ANT+ support we recommend antplus-arduino.

It measures 22.9 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
2 parts. 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.
From the reeganm/ANT-FeatherWing repository on GitHub, at the commit this page was made from: the board is Version 1/D52M Feather Wing.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
