Breadboard Specs and Setup:

Why I created this: I mainly use an ESP32 WROOM-32 Dev Module microcontroller for experimenting on a breadboard, but it was a pain most times because when placed it on a normal breadboard there wouldn't be any room when wanting to use the horizontal pins, because only one side would have 1 pin available for each GPIO/other pins for the ESP32. Ways to get across this is to use the smaller microcontroller, or get a module, or worse wire the pins across with the wire cables. THIS WAS AN INSPIRED DESIGN FROM Instructables.

All Breadboard Properties:

• 450 Pins in total
• Allows for standard metal contact clips to be inserted into the gaps underneath the breadboards
• A depth of 11.5mm
• Standard hole size of normal breadboards

Default Breadboard(Red): 

• Dimensions: 100mm x 50mm

ESP32 Breadboard(White):

• Dimensions: 100mm x 69mm

Preparation:

1. Remove the metal contact clips from an original breadboard - best to use tweezers
2. Place them onto the 3D printed breadboard/s, they should be a snug fit
3. Test as normal
