Building circuits just got easier with these tiny circuit boards that make all those weird parts fit into a standard solderless breadboard. The pins are labeled, and each board has a scribble strip so you can remind yourself what it’s for.
The Jack Crouton uses a 3.5mm PJ-301BM switched mono jack.
1. Solder two 4-pin headers on the bottom of the board (make sure they’re straight)
2. Solder the jack on the top of the board
