Grove module with 4 relay controled over I2C

The 4 relay unit integrates 4 two way modules (SPDT) which can be controled over I2C bus with a single protocol. This module do have an Arduino Library (made by M5Stack) and a MicroPython library (made by MCHobby).

The maximum control voltage is rated at AC-250V/DC-28V for the relay, and the current rated to 10A and the instantaneous current can hold up to 16A.

Each relay can be controlled independently and have a status LED (so you can know its state at anytime).

The typical application of this module are: digital signal switching, programmable power switch.
