Unit 2Relay
Description
Unit 2Relay is a dual relay expansion unit, integrating 2 contact-type relays, supporting on/off voltage levels of AC 250V / DC 28V, with a load rated current of up to 8A. Each relay is controlled by an independent IO and includes a status indicator light, suitable for power control of household appliances or for switching circuits in industrial equipment.

Learn
This relay is driven by IO output high/low level signals, so before connecting to the main controller, ensure that the connected port IO supports configuration as output mode. (Note: ESP32's G36 does not allow configuration as output mode, so PORT.B will not be able to drive properly)
