Three gold-plated half-size proto PCBs with white silkscreen markings

Adafruit

Adafruit Perma-Proto Half-Sized Breadboard PCB Pack of 3

SKU CH-EVPT-RX2HT

Pack of three half-size prototyping PCBs with gold-plated, thru-plated holes and no solder mask for easy trace cutting

  • TypeEngineering Development Tools
  • Pack of 3 boards lets you build multiple permanent circuits
  • Gold-plated pads resist oxidation unlike bare copper perfboard
  • Thru-plated holes add mechanical strength and survive repeated rework
  • Solder-mask-free design allows easy trace cutting for custom layouts
  • 2 mm drill holes accept components with large leads

Perma-Proto Half-Sized Breadboard Pack

This pack contains three half-sized breadboard PCBs designed for engineers and hobbyists moving circuits from solderless prototypes to permanent builds. The familiar layout mirrors a standard half-sized breadboard, complete with power bus lines and matching markings to simplify component transfer. It suits anyone who wants a durable, labelled platform for small to medium projects.

Installation and Common Issues

The 1.2 mm drilled holes accept components with larger leads, and all holes are thru-plated to resist pad lifting during rework. No solder mask covers the traces, so you can cut connections cleanly with a knife when a layout change is needed. The main difficulty is planning trace cuts in advance, because once a copper path is severed it cannot be restored without a wire jumper.

Sustained Use Behaviour

Gold plating on the pads prevents oxidation that degrades bare copper perf boards over time, keeping solder joints reliable through repeated heating cycles. The rigid FR4 substrate and plated through-holes maintain mechanical strength even when heavy components are soldered and desoldered multiple times. The board remains stable and conductive throughout long-term projects.

Highlights

  • Pack of 3 boards lets you build multiple permanent circuits
  • Gold-plated pads resist oxidation unlike bare copper perfboard
  • Thru-plated holes add mechanical strength and survive repeated rework
  • Solder-mask-free design allows easy trace cutting for custom layouts
  • 2 mm drill holes accept components with large leads

Questions about this item

How can I verify the board is ready for soldering after unpacking?

Check that every pad shows a continuous gold ring through the 1.2 mm hole and that the white silkscreen grid matches a half-size breadboard layout.

What comes in the package and what must I source myself?

Three bare Perma-Proto PCBs are included; you supply all components, wire, solder and any cutting tools needed to modify traces.

Which version should I choose for a compact permanent build?

The half-sized format replicates a standard half breadboard with four side power rails, making it the direct choice when space is limited.
