Product details

This relay board combines six independent switching channels with the powerful ESP32-S3 microcontroller for versatile control tasks in IoT projects. Two 10-pin expansion headers allow for the connection of additional modules, facilitating integration into existing systems. Thanks to integrated Wi-Fi and Bluetooth LE capabilities, the board can be configured and monitored wirelessly. The reset and boot buttons simplify firmware updates and system resets. A JST-SH connector (1.0 mm) is compatible with Qwiic/STEMMA-QT sensors, expanding its range of applications. Power is supplied via a DC input of 7 to 24 V, making the board suitable for both low-voltage and 24 V applications. The optically isolated relays enhance the isolation between control and load circuits. The robust layout is designed for industrial environments such as home automation, remote switching units, or automated test systems.
