LeMotechProject Box 5 Pieces ABS Plastic Electrical Project Case Small Junction Box for Electronics White 3.94 x 2.36 x 0.98 inch (100 x 60 x 25 mm)

One hole nees to fit romex..

Just what I needed and fast shipping.

I have used these boxes for two projects that use a ESP32-DevKitC-32E Development Board. In one case I have an Ultrasonic Module HC-SR04 Distance Sensor mounted in the box along with the ESP32 board. As can been seen I have cut holes through the box for the ultrasonic transmitter and receivers. The other use is only mounting the ESP32 board inside the box and running wires to a temperature and light sensor through small holes. In both cases I cut a slot for the USB connector to connect directly to the ESP332 board. The lid snaps on tightly, but is not overly difficult to remove.

They are fine but I should have measured b4 I bought these. I needed thicker ones. I just kept them. I had to drill holes on each end to pull cables through each side and make the connection inside the box.

Box's where perfect. Good quality.

It's just a box. Clever snap-on lid. Dimensions are given for everything except the one dimension that's hard to measure - that is the dimensions for mounting a board. So you have to try and hover your caliper over the mounting holes. As someone else has mentioned, there are no screws for mounting the board or even any part number for the screws. In short, the manufacturer could have made our job easy but chose to be lazy and make all of us figure it out. FYI, my best guess is 87mm x 48mm spacing for the PCB mounting screws, but my eyesight isn't what it used to be. I found some screws that seem to work so I don't have a part number. And finally, the mounting posts are too close to the corners leaving too little board material between the mounting hole and the inside wall. And watch out for the inside dimension because the wall slopes and gets smaller as the board is lowered down. So, if you use their dimensions, the board will be too big and require lots of hand filing. If you make the board shorter to fit the real size, the PCB will not have enough material between the mounting hole and wall. (This review is only for the case measuring 3.94 inches outside)

But they work great! My suspended desk slider needed raising juuuuuust a little bit. But not raise up so much my keyboard and mouse get squished. They look nice too, like it's part of the slider. These were a very inexpensive solution to an ergonomic problem. I used four of the five and maybe I can use the fifth as an actual container. Ha!

Used as junction boxes for LED light bars in my barn. I didn't want a big 4" box at 8-10$ a piece. lower profile and lower cost. Worked perfect for what I wanted. Just had to drill the holes.
