This is an ESP32 development board designed for marine/automotive engine monitoring application. Although the marine industry is the primary target this development board can serve as a good general purpose IO board for other projects as well.

The PCB form factor is design to fit into an optional 150mm x 90mm IP66 waterproof plastic enclosure. The board comes populated with pluggable screw terminals for ease of wiring.

This development board can be powered from up to 24Vdc with the integrated power supply. The integrated power supply is fused and features reverse polarity protection.

The development board can also be powered from the integrated USB-C programming port.

Features Include:

• 1 x ESP32-Wroom-N16 processor with integrated Wifi/Bluetooth
• 1 x NMEA2000/Canbus port (2 wire)
• 3 x 12V optically isolated digital inputs
• 2 x SPDT Form-C Relay Output
• 1 x OneWire bus (c/w integrated DS18B20 temperature sensor on board)
• 1 x 5V Analog input via built in 12bit DAC
• 4 x 18V Analog Input via ADS1115 16 Bit DAC
• 4 x 5.5V Analog Input via ADS1115 16 Bit DAC
• 1 x SPI Interface for TFT Display/Touch Screen
