very smart and low cost keypad , used to build an I2C arduino keypad ( used with mini oled display)
je recommande ce produit
Très petit et attention aux soudures des boutons, les pattes ne sont pas coupées et dépassent des pcb, elles sont très pointues !
Bien
Perfect. Exactly as described

These boards look good and the keys have a nice positive click to them. The only improvement I would suggest is that solder pads are made available on both sides of the board for the SIL connector. Whilst the matrix works perfectly, it is awkward to solder a SIL connector so that this can be used on a breadboard. I would still be happy to purchase them again - even in their current format.
I didn't solder it in yet but the quality of the material looks good and everything as promised
Works great with arduino or geek creit
ok
