Product Description

The Proto-Series is a family of solderable prototyping perf boards / breadboards with unique features, such as:
- Silkscreen printing on both sides. Dashed white lines indicate electrical connection.
- Separate ground and negative, which can be connected.
- 2 power-in methods: A) screw terminal, B) female power jack.
- 4 x M3 mounting holes: A) able to be separately grounded, B) able to stack multiple boards.
- Multiple power rails, which can be connected in various configurations.
- Central rail, which can be connected to ground.
The Proto-Series prototyping boards can be used in a range of applications, including:
- Prototyping your own circuit. Your circuit design from breadboard to protoboard.
- Interfacing microcontroller development boards (such as the Nano, or the ESP32)
- Data logging and other sensor data gathering
- Educational
- ... Tinkering!
The Proto-Full, Proto-Half and all of the PTSolns products come with full datasheets and other supporting materials such as 3D models, Fritzing models, schematics, tutorials, and much more. All of these are freely available on our "PTSolns Documentation Repository".
Proto-Series
This product is part of the Proto-Series. All the members of this series include:
- Proto-Full
- Proto-Half
- Proto-Mix (this product page)
- Proto-N2RF
-
Proto-ESP
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.
Features of the Proto-Full

The following are highlights of the Proto-Full. 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 (4 each) and both central rails 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 one or both of the central rails to ground (via 2-pin jumper)
- Access the ground-out pin
- Connect the ground to the negative (via 2-pin jumper)
- Electrical connections are shown by dashed white silkscreen printed lines. The layout of the Proto-Full is similar to the traditional breadboard. That is, rows of five are connected, as well as long sections of power rails.
- There are four positive power rails, four negative power rails, and two central rails. Any of these can be connected (via 2-pin jumper) to realize rails that span the entire board.
- Silkscreen printing on both sides.
- 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.
