Prototyping PCBs are really handy for making your circuit permanent, allowing you to solder components together using prototyping wire (or for short distances, bridging with solder!).
This is a 10-pack of 5x7cm double-sided Proto PCBs with a 2.54mm pitch (the space between the pads). 2.54mm is arguably the most common pitch, used on most popular development boards from the Raspberry Pi 5's GPIO header to the Raspberry Pi Pico pins to the XIAO and more!
The PCBs are 1.6mm thick, green in colour, and feature corner M2mounting holes and side row/column labelling to help you find your way. The pads are not connected together.
We're showing a Seeed XIAO RP2040 in one of the product images (not included) to give you a real-life feel for the size of these.
