The 12V -> 5V @ 4A Buck Converter + ELRS Board is intent for several foam fixed wing planes at the Waterloo Aerial Robotics Group. It includes a ESP32-C3 for PWM signaling and SX1281 for RF control over ELRS, as well as the requisite power electronics to have the system be powered by a single 12V input (1x 3S battery).
Please read the usage section for important details!
...
This implementation is designed to optimize and integrate the system of the foam fixed-wings, which currently requires a separate buck converter (previously using 12V->5V @ 5A Buck Converter Board), and a commercial, off-the-shelf ELRS receiver (https://betafpv.com/products/elrs-micro-receiver).

Do NOT leave the U.FL connector unoccupied when powering on the device. This could Without a load to match the output impedance, any power transmitted will reflect back as a standing wave and likely destroy the amplifier in the SX1281 RF IC.
