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 board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- 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 (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- solderless breadboard
- A reusable board with rows of internally connected holes for building circuits by pushing in components and jumper wires, with no soldering required. It lets you prototype and rewire a circuit quickly and reversibly before committing to a permanent, soldered build.
