4×4 Matrix Keyboard Module with 16 buttons
Small in size and hence Save space
More convenient to use
Expanded development application modules for single chip
With 16 keys and 8 pin

The 4 x 4 matrix keypad usually is used as input in a project. It has 16 keys in total, which means the same input values. The 4 x 4 Matrix Keypad Module is a non-encoded matrix keypad consisting of 16 keys in parallel. The keys of each row and column are connected through the pins outside – pin R1-R4 as labeled beside control the rows, when L1-L4, the columns.

A 4×4 matrix keypad consisting of microswitch buttons. The module has four holes 3mm (M3) holes for mounting. The pin designations on each PCB are shown on each PCB. Four pins are thus used as an ‘x’ coordinate and the other 4 as a ‘y’ coordinate.
The module is already equipped with a soldered pin-headers.
