Relays Box 2,0
thingiverse
Hello I have constructed a small relay box that enables me to control my 3D printer's power via Octoprint. This box is designed for two modules with dimensions of 18.2 × 53.15 × 1.5 mm The box measures 80 × 70 × 27.3 mm, plus an additional 1.2 mm cover thickness. Here are the links to the module: 1. Amazon: https://www.amazon.de/gp/product/B00ZR3B252/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 2. Aliexpress: https://it.aliexpress.com/wholesale?catId=0&initiative_id=AS_20181117142840&SearchText=relay+module+3.3v To use this module with Octoprint, you'll need to install the PSU plugin first. Once installed, connect the module to your Raspberry Pi: Module / Pi Pin IN connects to pin 3. GPIO2 Pin GND connects to pin 6. Ground Pin VCC connects to pin 1. 3.3V (or pin 2 with 5V, depending on the module; my module works better with 3.3V)
