This is an ESP32 development board designed for marine/automotive engine monitoring application. Although the marine industry was the primary target this development board can serve as an excellent general purpose IO board for other projects as well or as a learning tool for things like CanBus, NMEA200 etc. This version is cost reduced and targeted as an entry level board for play with on the bench.

The PCB form factor is design to fit into an optional 115mm x 90mm IP66 waterproof plastic enclosure.

This development board can be powered by 12-24Vdc or integrated USB-C. The integrated power supply features reverse polarity protection and built in fuse.
