⚙️ Elevate your Raspberry Pi to industrial automation royalty!
The 8-Relay Expandable Card transforms any Raspberry Pi (Zero to 4) into a powerhouse controller for AC/DC loads, supporting up to 64 relays via stackable layers. Each relay switches up to 120VAC/24VDC at 8A, with N.O./N.C contacts on heavy-duty connectors. Featuring RS485 MODBUS communication, I2C-only interface for GPIO freedom, status LEDs, and manual control, it’s engineered for IoT, home, and industrial automation with robust software support including Python and Node-RED.
