WiFi 4 RELAY HOLDER
thingiverse
This is a WiFi Relay Board Holder for ESP8266, specifically designed for 12V 4-Relay PCBs with a limited number of mounting holes. To provide secure and reliable installation, I created this holder to isolate the back of the board from whatever surface it's mounted on. The Clamping Bar can be equipped with a thin layer of foam tape to minimize relay vibration and noise. Two #4x 1/2" Pan Head Screws securely hold the low-voltage side of the PCB in place, while two #6x 1-1/2" Pan Head Screws firmly attach the Relay Bar. If you plan to use this board with high voltage, it must be installed in a UL or CSA-approved electrical box. However, note that WiFi functionality will not work within a metal enclosure. For 12V applications, the PCB can be mounted directly to plywood without any protective covering.
