ESP32 CAN Bus Expansion Board

Description

ESP32 CAN Bus Expansion Board

Introduction: This ESP32 CAN Bus Expansion Board suitable for making rapid prototyping based on The Controller Area Network (CAN) bus which is a robust and widely-used communication protocol in various industries, including automotive, industrial automation, and more. It allows for reliable data exchange between nodes (devices) in a network, even in noisy and electrically harsh environments.

This 3 in 1 board comes with DC-DC converter to regulate the operating voltage of ESP32 using MT2492 chip , also all GPIO brought by male header for easy access for any IO pins .

ESP32 microcontrollers, developed by Espressif, are known for their performance, versatility, and extensive peripheral set. They are a popular choice for IOT systems and are well-suited for CAN bus applications.

We developed a small expansion board for SN65HVD230 CAN transceiver base board suitable for ESP32 Wifi development board ,the boards includes DC-DC power converter based on MT2492 to make the board compatible with any 12V system easily  ,you can buy the empty PCB and solder it by your self to increase the hardware troubleshooting skills and to understand the details also.
