+Important Hint
+--------------
+
+Although the term NMEA2000 is used here, the software or device is __not a certified NMEA2000 device__ as it did not pass any approval process.
+There are chances that the software / device does not follow the NMEA2000 specification at several points.
+If you connect the device to your NMEA2000 network you do this on your own risk.

 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.
