 Goal
 ----
-Have a simple ready-to-go ESP32 binary that can be flashed onto a [M5 Atom CAN](https://docs.m5stack.com/en/atom/atom_can), potentially extended by an [Atom Tail485](https://shop.m5stack.com/collections/atom-series/products/atom-tail485?variant=32169041559642) for NMEA0183 connection and power supply
