What is it?

The Easy Test Extension Board is a convenient board/tool designed to simplify signal testing from standard headers or connectors. It provides accessible test points with hooks, allowing hardware engineers to easily connect tools like multimeters, oscilloscopes, or logic analyzer's probes for efficient signal testing.

Why did you make it?

Whenever I debug a module connected to my core board, like a Raspberry Pi or BeagleBone, I often find it difficult to access the signals on the header pins. Typically, I have to manually solder extension wires to the signals after multiple failed attempts to connect directly. While this is manageable for me as a hardware engineer, it becomes a distraction when a software engineer asks me to assist with signal access. That’s when I thought, why not design a board with accessible test points to eliminate the need for manual work? This idea led to the creation of this board, and the results have been excellent.

What makes it special?

The board is simple and easy to use—just plug and play, like most standard boards. It features 20 pins on each side,with pitch 2.54mm, providing ample connectivity for most boards on the market. There are two versions available: one with male-to-male headers and another with female-to-female headers. If you need a female-to-male configuration, you can simply connect the two types together. All the pin orders are clearly labeled, eliminating the need to count pins each time you test.
