Six prototyping boards from Wright Hobbies, a new uCHobby sponsor. This article is a brief review of the new boards. A second comment contest where you can win a set of these boards is also announced.
We announced the Wright Hobbies giveaway sponsorship in this previous article along with a comment contest. There have been a lot of great comments in favor of the sponsorship idea. I have high hopes that sponsorship in exchange for giveaways will be a very successful project and that we will see other sites adopt this idea as well.
In this article I review each of the six prototyping boards including links and pricing information. Come look at these boards and get inspired to enter the comment contest, submit an article, or a link to uCHobby to receive a set of your own.
Each of the boards is reviewed below. Click on the board picture to see more detail. These pictures were taken using my flatbed PCB scanning technique. You may find the detailed shots at Wright Hobbies are better.
Six different prototyping boards are included in the giveaway package. Two of these boards are not currently for sale at Wright Hobbies. Each of the boards has a silkscreen side with white border lines showing how the pads are connected.
PB20 Prototype Board
This board has a large 0.1 inch grid of plated through holes with square pads on both sides to make it convenient for soldering down components. The board is 55x66mm or about 2.5×2.25 inches and costs about $4.
Two sets of pins, 2×16, arranged in connected pairs on each side with a grid of 484 pads in the center area. The details at Wright Hobbies indicates that the 2×16 pad sets are good for headers but since the pins are connected together we are talking about a single row header such as you find on an LCD display. This picture is of the solder side of the board so we do not see the white silk screen border which indicates the connections between pads. Except for the 2×16 header rows, the grid is of unconnected pads.
The first idea that popped into my mind for this board was an LCD interface board. Use the header row to connect the LCD module, add the parts to include a few buttons and an I2C chip to make a ready-to-go user interface.
PB10 Prototype Board
This may be my favorite prototype board. Similar to the P20 in size it also has the header pad sets on each end. But this board is arranged like a solderless breadboard with rows of connected pins with a gap, ideal for standard DIP ICs. The center two rows are connected to make power rails. It should be very easy to transfer a project to this board when you are ready to move into the real world.
The PB10 is 55x65mm or about 2.5×2.2 inches and costs about $4.
This very nice board is actually 4 boards in one. There are several connected pads on this 0.1 inch gridded board. Pre-scoring on the board allows you to break it into two or four separate boards. If you need a small board for a project, snap one off. The arrangement of the connected pads makes good areas for ICs and power rails. I bought a 5 pack for my home lab a few weeks ago.
This board costs about $2.50 and has an overall size of about 3×2 inches. Each of the smaller boards is about 1×1.5 inches.
This board is much larger, 4.75×3.15 inches and is a basic 0.1 inch grid of copper pads. As you can tell from it’s tan color, the material is phenolic . Phenolic is lower cost than standard PCB material, which makes this a low-cost option for prototyping at about $2.50. Phenolic is fine for prototype PCB work and is easier to cut or snap to size. Just score it along the holes and snap away the excess.
Special Board 1
This board is not currently shown at the Wright Hobbies site. It has a 0.1 grid of pads which are connected in rows in the long direction of the board. It is also made of phenolic. The idea with this board is that you cut the traces to separate the pads. By using a few short jumpers and cutting the traces you can wire up a prototype quickly.
The board is about 2.16×3.65 inches
Currently Wright Hobbies does not sell this board online but we do include it in the giveaway/contest package.
This board is available – pb9412 Stripboard at Wright Hobbies
Special Board 2
"right" border="0" /> I may have saved the best prototype board for last. This board is ROUND! You can use it as a square board or break away the corners to get a round board. Eddy designed this board to make it easy for people building round robots. The silk screen shows the clever arrangement of connected pins.
I’m sure this board will be available at Wright Hobbies at some point but for now, you can get one in the package from uCHobby.
The board is about 3 inches square with the round part being about 2.75 inches in diameter.

Yes, another comment contest for these boards. In addition to the contest announced in the previous sponsorship article, we will be giving several of these prototype board packages away for comments here.
Eddy suggested that we give some packages away for good ideas on how to use them so that is how we will do it. Make a comment on this article with a brief description of how you will make use of the boards. I will select one or two random winners from all the good comments and one or two favorites to receive free kits.
Visit Wright hobbies and thank Eddy for making this possible. Spread the word about the contest and good luck.
