The Adafruit METRO Mini 328 V2 is a compact and powerful development board designed for those who want a tiny

Relay 4 Zero is designed for triggering at low voltage levels

We even wrote a very nice library for the backpacks in both Arduino & CircuitPython so you can get running in under half an hour

An optional LED with a built-in resistor is included

USB Type C to DB-9 Adapter Cable - 1.5m Long 2 channel relay for raspberry pi multi-functionThis USB Type C cable adds a DB 9 (DE 9) serial port to your computer or laptop, compatible with MacOS X, Linux, and Windows. It provides approximately 6V serial (RS232) levels, making it ideal for connecting to older devices like GPS units, handhelds, and programmers with DB9 connectors. Unlike some cheaper RS232 cables that output 0 5V and may not work reliably with all devices, this adapter uses a true voltage doubler inverter for compatibility.
