LM2596 + 1CH Relay Case with Extrusion Rail
Description
Case for LM2596 DC-DC Converter and 1 channel relay board with optocoupler with extrusion V-Slot rail. I am using this at the back of the Ender 3 Pro, right on the extrusion under the power supply. This is used with OptoPrint on Raspberry Pi, which controls the relay (turning the printer on/off) and also the LM2596 provides power for the RPi.
