ESP32 Breadboard Brace

thingiverse

If you've worked extensively with various ESP32 or ESP32-S2 development kits, you're likely aware that they often don't fit neatly onto standard breadboards or even two attached standard breadboards if you want access to all the pins. This 3D printed solution addresses that issue. It requires two full-length standard breadboards (830 tie-point, four power rails). The brace is designed to combine a couple of modified standard breadboards for a perfect fit when working with ESP32 or ESP32-S2 development boards. The process begins with printing the 3D model – both the .stl file and the original .f3d (Fusion 360) file are included. Next, you'll need to modify two standard breadboards as described below. Step one involves cutting off the rightmost strip from the first standard breadboard and removing its tabs. Step two requires trimming the tabs from the second standard breadboard. Step three is about removing the protective film from the sticky pads on each breadboard's bottom and placing them (hole side up) in the 3D printed brace. Please refer to the included pictures for correct orientation, but essentially, the first modified breadboard goes into the smaller slot with its power rails closest to the outside of the 3D printed brace, while the second one goes into the larger slot with its row numbers aligned to those on the already placed breadboard. The end result is a very stable and secure solution for working with your ESP32 or ESP32-S2 development kit boards.
