Proto-Series
This product is part of the Proto-Series. All the members of this series include:
- Proto-Full
- Proto-Half (this product page)
- Proto-Mix
- Proto-N2RF
- Proto-ESP ... coming soon!
Features of the Proto-Half

The following are highlights of the Proto-Half. For full details please see the datasheet which can be found in our "PTSolns Documentation Repository".
- Two power-in methods: A) screw terminal, B) female power jack.
- Positive/negative power rails (2 each) and central rail are disconnected by default. Various configurations can be realized by soldering across the respective 2-pin jumpers.
- Canadian designed.
-
Ground and negative terminals are treated separately, and by default are not enabled. The user has the options to:
- Connect the central rail to ground (via 2-pin jumper)
- Access the ground-out pin
- Connect the ground to the negative (via 2-pin jumper)
- Silkscreen printing on both sides.
- Electrical connections are shown by dashed white silkscreen printed lines. The layout of the Proto-Half is similar to the traditional breadboard. That is, rows of five are connected, as well as long sections of power rails.
- Four mounting holes can be separately grounded (see second image for grounding options). Mounting holes can also be used to stack multiple boards.
- Lead-free surface finish RoHS.
Endless Applications

Rapid Prototyping
Realize your circuit design and make it quickly using the Proto-Full and Proto-Half prototyping boards. With the configuration options the user can utilize the rails and power input as best fit their design requirements.
From Breadboard to Protoboard
Move your project from a temporary breadboard over to a permanent installation on a prototyping perf board. The Proto-Series boards make this easy and efficient.
Interface with Modules
The Proto-Series is versatile and can easily interface with microcontroller development boards such as the Nano, Pico, etc. Interface sensor modules via screw terminals or headers quickly.
