Wemos D1 Mini Relay Case

thingiverse

I remixed the Wemos case by Rickvillela to incorporate a different relay, as mine seemed offset from the board, requiring an added length. The relay I used was purchased from Aliexpress. To ensure terminal protection and safety for 240v switching, I added terminal covers where necessary. This modification is crucial for reliable operation with high-voltage applications. I understand that in the original image of the relay and Wemos combination, the Wemos board isn't soldered to the headers. The demonstration showcases an offset board, which is a key aspect of this project. Currently, I'm out of D1 Mini boards, so I used a Pro Micro instead, opting not to waste it on a simple relay switch. After carefully soldering all components together, UPDATE: I realized that the Pro Micro lacks chips on its bottom surface, unlike the standard D1 Mini. To address this difference, I added one chip for each board type - the Pro Micro and the standard D1 Mini. This happy accident was unforeseen when assembling the project; it turns out the onboard LED glows blue when the system is off.
