Perma-Proto - Half-sized Breadboard Flex-PCB
By Adafruit (1518)
MCM Part #21-14605
Make your next project super-flexy with a prototyping board that can twist and bend. We took our lovely classic perma-proto design and had it made from incredibly thin polyamide film.
It's extremely bendable, and you can cut it easily with scissors. It has a bend radius of 1cm or better (you can also crease it but that might break a trace if you crease a trace) and you can solder any components to the pads.
