My ESP32 board (doit 36 pins) is too wide so it's not breadboard friendly (only one row on one side of the breadboard is available).

I made this fast to print little thing to attach a small 60x40 pcb holding the ESP32 to the breadboard. It can be used for any other boards that are not breaboard friendly as far as they fit on the pcb (like some ESP8266 adapter plates).

It's made for a 8.5 x 5.5 cm breadboard

To attach the pcb you will need small M2 screws or you cau use hot glue. To protect against shorts I suggest to isolate pins under the pcb with some electric tape.
