Copperhill Technologies introduces the ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module to support IoT (Internet of Things) applications connected to CAN Bus, SAE J1939, and NMEA 2000 serial networks.

The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. It opened the door to a multitude of low-cost, high-efficiency IoT applications. The ESP32 board supports a variety of wireless communication methods such as Bluetooth Classic, BLE (Bluetooth Low Energy), and WiFi. Other serial protocols include SPI, IIC, I2S, UART, and, after all, Classical CAN, allowing the connection of automotive (CAN Bus, SAE J1939) and maritime (NMEA 2000) applications to the cloud.

Compared to standard ESP32 modules available in the market, the Copperhill device is the only one that comes with an onboard CAN Bus Transceiver. It also supports an external 12 VDC power supply with reverse polarity protection, making it suitable for automotive and industrial applications.

Programming is accomplished through the popular Arduino IDE, while the board is connected to the USB-to-Serial converter with USB-C connector, automatic bootloader and reset.
