M5Stack 2-Channel SPST Relay Unit


Description

2-Channel SPST Relay Unit is a 2-channel SPST relay module, equipped with two high-current relays that work under AC250V 8A or DC28V 8A. Each relay adopts independent IO control, and status indicator LED. It is suitable for home appliance power control, or ON/OFF switch for industrial equipment.

The relay is driven by IO output high and low level signals, so before connecting to the main control, please make sure that the connected port IO supports configuration as output mode. (Note: G36 of ESP32 is not allowed to be configured as output mode, so PortB will not be able to drive normally)
