Teensy 4.0 With NMEA 2000 Connector And 240 x 240 IPS LCD for Marine Applications

This board carries an Arduino-compatible Teensy 4.0 microprocessor system, a 240x240 pixels IPS LCD, and a Micro C NMEA 2000 connector. The board receives power through the 12 VDC NEMA 2000 connector that feeds an onboard 5 VDC regulator. There is also a 4-way 1mm (Qwiic) IC2 connector for external sensors. The example sketch reads data from an NMEA 2000 wind sensor and a temperature sensor and displays the reading on the LCD.

espBerry - ESP32 Development Board with Dual Isolated CAN Bus HAT

The espBerry DevBoard combines the ESP32-DevKitC development board with any Raspberry Pi HAT by connecting to the onboard RPi-compatible 40-pin GPIO header. The Dual Channel CAN Bus expansion HAT, designed for the Raspberry Pi, supports the full CAN2.0 Standard, and it features multi onboard protection circuits, high anti-interference capability, and reliable operation.

The CAN (Controller Area Network) is a communication system used in modern vehicles that allows electronic control units (ECUs) to exchange information quickly and reliably. Instead of connecting every module with separate wires, the CAN bus enables all modules to communicate through a shared two-wire network.

Functions of the CAN Bus

Enables communication between vehicle control modules such as the ECU, PCM, BCM, ABS, TCM, and SRS.

Reduces the amount of wiring, making the electrical system lighter and simpler.

Provides fast and reliable data transmission.

Allows modules to share sensor data, including vehicle speed, engine temperature, throttle position, and engine load.
