Flipper Zero Prototyping Board Kit – Breadboard Expansion Set with 1 Large and 2 Small Boards, Includes Matching GPIO Header Pins and Jumper Wires – DIY Hardware Development for Flipper Zero(Black)

As described, perfect for prototyping

The boards are nice without fiberglass burrs, but there are no traces even though there are outlines that make you assume that those through whole areas are electrically connected but they are not. I spent a good while wondering why my circuit didn't work only to realize that it was not electrically connected to the headers.

This kit comes exactly as pictured - three PCBs, three sets of pin headers, and a bundle of jumper wires. The purpose of these boards is to provide you with structure to make your connections - but they do not make any connections, leaving that up to you to terminate with solder and wires as you see fit. The PCBs seem well made and sized for purpose, and the headers also are a nice fit.

These boards are going to be very helpful for development with the Flipper. I like how you get three boards and they include pins for all three. The wires will probably not be that useful to me. They are very thin and I typically like to use a larger gauge wire. There are no traces on the boards, so every through-hole is independent. I almost wish that the connectors were pre-soldered, but I don't mind doing it myself. Overall, these are good dev boards to use with the flippers. Can't wait to get some chips to do some testing!
