From the project

Anubis is a project to create the ultimate open source RC controller utilizing inexpensive consumer parts and clever programming.

A compact open-hardware support board for a DIY ESP32-S3 RC transmitter.

Anubis is an open hardware and open firmware RC controller project built around accessible DIY parts, modern radio-control features, and a design that builders can understand, repair, modify, and improve.

This repository contains the custom daughterboard for the Anubis controller. It sits under a Hosyond 2.8 inch ESP32-S3 display board and turns the early wiring-heavy prototype into a cleaner, more repeatable hardware platform.
