Human: Easy Installation Guide for Raspberry Pi 3 with a Single-Channel Relay Module Important Notes for the Hardware Setup: To secure the RPi from the bottom, use four #4 x 1/4" sheet metal screws. If you prefer an alternative option, consider using M3 x 6mm screws, but be aware that they will fit extremely tightly and are not recommended. For securing the top part to the bottom, use four #4 x 3/4" sheet metal screws as a standard approach. Alternatively, you can opt for M3 x 18mm screws; however, keep in mind that they might also have an extremely tight fit, so it's best to avoid them if possible. For both alternatives, consider using M2 x 6mm or M2 x 18mm screws with heat set inserts from McMaster (#94180A312) for a more secure and less stressful assembly process.
