This module utilises the ESP32 microcontroller, which features a powerful Xtensa 32-bit LX7 dual-core processor running at up to 240 MHz. It supports both 2.4GHz Wi-Fi and Bluetooth LE for flexible wireless communication with excellent RF performance. The module includes a high-capacity relay rated at 10A for 250VAC or 30VDC, suitable for robust applications. It comes with an isolated RS485 interface for connecting to various Modbus devices or industrial sensors. Additionally, it has a 40-pin header compatible with some Raspberry Pi Pico HATs, allowing for easy expansion to integrate functions like RTC, CAN, RS232, LoRa, or additional sensors. Power management is straightforward with an onboard USB Type-C port for power, firmware updates, and debugging, as well as a power supply screw terminal that accepts 7-36V inputs, ideal for industrial settings. The module’s design includes optocoupler and digital isolations to minimize interference from external sources, ensuring reliable operation. It provides a self-contained power supply isolation, so no extra power source is needed for the isolated terminal. Also included are a buzzer, RGB LED, and indicators for power and RS485 activity, making it easy to monitor system status. The durable rail-mounted ABS case makes installation simple and secure.
