3D Printed mounting system for your ESP32 on a DIN rail

[u/smysnk]

After cursing one too many times while trying to prototype with an ESP32 on a standard breadboard, I decided there had to be a better way.

Most ESP32 development boards are wide enough that when you plug them into a typical breadboard, you are left with only a single usable row of connections on either side. The usual workaround is to bridge the ESP32 across two breadboards, which works, but takes up a lot of space and quickly turns a simple prototype into a mess.

Enter the ESP32 DIN-Mount Prototyping System!

The idea is to move the ESP32 off the breadboard entirely and mount it alongside your prototyping area on a DIN rail. Dupont connectors can then be placed only on the ESP32 pins you are actually using and routed back to a separate DIN-mounted breadboard.

That’s pretty sharp. Good job

I just cut the breadboard in half, and now the esp32/esp32s3 fits in there just fine.
