Hi Very suitable prices with free download
The keypad is 7 cm wide by about 7.75 cm heigh, very thin ( 1 mm) and flat back.
I really like this product - especially at the price provided! Unfortunately no manual follows, and no explanation of the individual pins are provided, so this will have to be figured out manually.
muy buen aspecto incluso trae una papel auto adhesivo en la parte trasera
