uPesy Prototyping Boards Datasheet

Here is the technical documentation for uPesy’s prototyping boards, which are used to solder electronic components to them using a soldering iron and solder wire.

These prototyping boards have the following characteristics exactly like solderable breadboards . Unlike classic protoboards with holes isolated from each other, here on these boards, the holes are connected by rows as on a classic breadboard.


These protoboards are perfect for creating a permanent version of your original breadboard circuit with reliable connections.

The different sizes

The protoboards are available in 3 different sizes corresponding to the three types of breadboards commonly used:

  • The Mini variant corresponds to the size of a Mini breadboard of 170 holes (17 rows) with dimensions: \(51mm \times 38mm \times 1.6 mm\) .

  • The Medium variant corresponds to the size of a 420 holes breadboard (30 rows), i.e., \(87mm \times 53mm \times 1.6 mm\) .

  • The Large variant corresponds to the size of a classical breadboard of 800 holes (63 rows), with dimensions: \(171mm \times 53mm \times 1.6 mm\) .


Here are the main characteristics of these prototyping boards:

  • Pads have a 2.54mm (0.1”) pitch.

  • Fixing hole of diameter M2 for the smaller ones, M3 for the bigger ones. They allow fixing the boards with standoffs (spacers).

  • 1.6mm thick FR4 PCB with pre-tinned pads for easy soldering.

Particular feature: Pads connected in rows

The pads are routed together as follows (the red lines represent the tracks on the board):

It is the same as on a standard breadboard

Feeding tracks

On the Medium and Large variants, power supply tracks on both sides are separated. To have the same power supply, connecting them with a small soldering point at the location provided for this purpose is possible. They are on the top side (the one with the logo).

  • The bottom one allows to connect of the two ground tracks (- ) :

  • The top one allows you to connect the two positive tracks (+ ) :

For example, we can connect only the ground and have a 5V supply on the track + on the left and 3.3V on the right.

Usage recommendations

The boards must be used for an electronic circuit with low voltage (< 48V DC).


Do not use with mains voltages of 220V. The distance between the pads needs to be bigger, and the circuit is too much uncovered.
