“I cannot stress enough that you MUST get a couple of these, i got one to try out, and by the end of the 3rd day, i already had 4 ideas for them, plus a case 3d printing! cheaper than the pro-micro if youre looking for a usb HID controller, plus they are cheap as chips (excuse the pun haha)”
“Lots of features, small package, great price. Shipping was super quick as well. Sticker with pin numbers optional (3 options along with a blank white or leave it without - see pic).”
