Description:
The Pi prototype hat breadboard can provide a good prototype development platform.
You can build your own circuit on this breadboard.
Combined with the function of the Pi GPIO pin to achieve many different functions, you can build an electronic experiment environment.
Features:
Easy to assemble
Prototype breadboard
GPIO compatible
With write-protect ID EEPROM
Package Includes:
4 x RPi Prototype Hat Breadboard
8 x Screws
4 x Pin Header
4 x Hollow Copper Pillar

Suitable for Raspberry Pi 4B / Raspberry Pi 3/2 Model B/ Raspberry Pi 1 Model B / Pi 1 Model A+.
PCB Dimensions: 57mm x 66mm, Thickness: 1.5mm.
To kick off the HAT party, we have this proto inspired plug in daughter board. It has a grid of 0.1" prototyping soldering holes for attaching chips, resistors, LED, potentiometers and more.
The holes are connected underneath with traces to mimic the solderless breadboards you're familiar. There's also long power strips for +3V, +5V and Ground connections to the Pi.
Package Includes: 4x PCBs, 4x 2x20pin connectors, 1x Screw Set
