Each panel comes with 12 individual breakouts to solder up and assemble to your favorite breadboard, perf-board, etc.
It's a ton easier than trying to get a drink order in at the club in Bushwick, you get an easy way to get started on a DIY synth project!
A couple of months ago Adafruit started carrying packs of colorful step switches reminiscent of the 16-step sequencer keys on TR-808 synthesizers. They gave folks the heads up that the switches are not breadboard or perf-board friendly i.e. would need to either be hand-wired or designed into a PCB.
And then they heard LCD Soundsystem is coming back on tour - so they sold their guitars to buy turntables & got cracking on a break-apart panel of step-switches to evoke the spirit of electronic music and DIY venues.
Please note, each order comes with one sheet of assembled PCBs that can be broken apart - Adafruit include top and bottom railing bits to help keep it nice and flat during shipment.
Does not include headers which you'll need if you're going to plug these into a breadboard
