Perma-Proto prototyping PCB for 40-pin Raspberry Pi, breadboard layout, with 2 × 20 header to solder (kit) – Adafruit 4354

Key features

• Layout of a full-size breadboard (60 rows instead of 63) with the same markings, to transfer a circuit from the breadboard easily
• Built-in Cobbler: all GPIOs of the 40-pin header broken out to labelled pads
• Bottom side with 5-hole pads like a classic breadboard and no solder mask, to cut traces easily when needed
• 4 side power rails with positive/negative markings
• 1.2 mm plated through holes that fit even parts with big leads and withstand rework
• Gold-plated finish that does not oxidise like bare copper; plenty of mounting holes
• For Raspberry Pi with 2 × 20 header: B+, A+, 2, 3, 4, Zero

Technical specifications

• Pads: 20 dual rows of 4 holes connected to the GPIO, 2 dual rows of 4 holes, 38 dual rows of 5 holes
• Power rails: 4, with +/− markings
• Holes: 1.2 mm diameter, plated
• Material: FR4, 1.6 mm thick, gold-plated finish
• Dimensions: 160 × 50.8 mm
• Compatibility: Raspberry Pi B+, A+, 2, 3, 4, Zero (2 × 20 header)

Typical uses

Turning Raspberry Pi breadboard prototypes into permanent circuits, custom add-on boards, interface circuits for sensors and actuators.
