Working with different Dev Kits from Espressif? Do you want to mount these to a DIN rail?

Do you just want to use terminal blocks with screws instead of soldering?

Here you go! This little board accepts most of the ESP boards out there:

• ESP8266 Dev Kits (30 and 38 pins, wide and narrow boards)
• ESP8266 WeMos D1 Kits and the like
• ES32 Dev Kits (30 and 38 pins, wide and narrow boards)

However it does not fit for Arduino Nano or similar smaller boards.

There are 3mm holes with a distance of 300mm for mounting to a DIN rail clamp which you can print on a 3D printer (found here). Additionally there are 3mm holes on all the four corners form mounting using stand-offs.

To complete your board, you will need:

• 4 x 2.54mm/0.1" Pitch PCB Screw Terminal Block Connector with 10 pins
• 6 x 2.45mm/0.1" Pitch Female Pin Header for 10 pins
