AI Overview
For Raspberry Pi prototyping, the most useful picks are GPIO breakouts + a prototyping HAT/PCB + jumper wires/breadboards.
Fast GPIO-to-breadboard prototyping (no custom PCB)
- Raspberry Pi GPIO Ribbon Cable - 40-pin, 6 (RPi 3, RPi2, B+) (40-pin, 6") helps you route the Pi’s header to a breadboard-style setup neatly.
- Jumper Jerky - Female to Female (40 leads, F/F, 185mm) is the go-to for quick wiring from GPIO pins to modules.
- Maker Essentials - Mini Breadboards Jumper Jerky bundles mini breadboards + jumpers for an easy starter prototyping setup.
Soldered “permanent prototype” boards (turn breadboard ideas into something robust)
- Adafruit Perma-Proto HAT for Pi Mini Kit - With EEPROM ($16.35) is a full-size 40-pin HAT-format protoboard with EEPROM, ideal for building a custom circuit that mounts directly on the Pi.
- PiBreak Raspberry Pi Prototyping Board ($1.10) is a compact, low-cost prototyping board with labelled GPIO breakout and prototyping area.
- Adafruit Perma-Proto 40-Pin Raspberry Pi Breadboard PCB Kit - with 2x20 Header ($15.95) combines a protoboard with a built-in 40-pin Pi breakout concept for more structured builds.
Helpful add-ons for learning + quick pin reference
- STEM components for Raspberry Pi ($23.35) provides common parts (LEDs, resistors, buttons, etc.) suited to Raspberry Pi electronics learning/prototyping.
- RasPiO® GPIO Ruler ($11.40) is a handy GPIO pinout reference that slips over the header to avoid miswiring.
