The Adafruit Perma-Proto Bonnet Mini Kit is a prototyping daughter board sized for the Raspberry Pi Zero. It plugs directly onto the Pi's 2×20 GPIO header and provides a grid of 0.1″ soldering holes connected in a familiar breadboard pattern — making it easy to transfer circuits from a solderless breadboard to a permanent soldered design.
Nearly every GPIO pin is broken out near the top of the board, along with dedicated power strips for +3V, +5V, and ground. Unlike the Perma-Proto HAT versions, this Bonnet does not include an EEPROM, so it can be stacked with other Bonnets and pHATs without address collisions.
Key Features
- Breadboard-Style Layout – 0.1″ grid with connected pads matching solderless breadboard patterns
- GPIO Breakout – Nearly all Pi GPIO pins broken out along the top edge
- Power Rails – Dedicated +3V, +5V, and GND strips
- No EEPROM – Stack-friendly design avoids address collisions with other HATs/Bonnets
- Pi Zero Form Factor – Sized for Pi Zero but fits any Pi with a 2×20 header
Ideal For
- Custom circuits and add-ons for Raspberry Pi Zero projects
- Transferring breadboard prototypes to a permanent soldered board
- Stacking with other Bonnets and pHATs (no EEPROM conflicts)
Package Contents
- 1× Perma-Proto Bonnet PCB
- 1× 2×20 Female GPIO Header
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- solderless breadboard
- A reusable board with connected holes for building temporary circuits without soldering. It matters in beginner kits because students can change wiring quickly and safely while learning how components connect.
