WLED ESP32 Electronics Box

There are many ESP32 / WLED cases out there, right, but I wanted one that was both spacious enough for me to still use jumper wires on the ESP32's pins and also had space for my specific buck converter. The circuit is simple, I had a 24V LED strip, so it's designed to have a 2A 24V DC barrel jack power supply coming in, that goes both straight into the LED strip, and is used to power the ESP32 as well via an adjustable buck converter set to 5V out which goes into the 5V pin on the ESP32. Then there is space for 2x 5-hole Wago connectors.

The lid of the box has a 1-layer deep inset “WLED” label on the top. The lid also has four little click-in nubbins so that it stays firmly in place when inserted into the main housing. The main housing then has two little cut aways for putting your thumb under the lid to more easily lift it off. There is a 1-layer deep inset labelling each component's area as well for easy assembly.

In detail, this is designed to house the following components:

1) a barrel jack with +/- blocks

2) an ESP32 NodeMCU

3) an adjustable buck convertor

4) two 221 5-pin Wago connectors

As ESP32's come in many variations, the standoffs here are designed for an ESP32 with the mounting holes in each of the four corners center to center 51.12mm x 23mm apart.

The buck convertor I used is this common one. It's got two mounting holes, in the top left / bottom right only (looking down at the top), and those are spaced (again center to center) 30.96mm x 17.32mm apart.

The little wago clamping area is designed to house two back-to-back 221 5-block wago's.

Hope this is useful to someone else!
