More info


Keyboard module with 10 tact switch buttons. The output of each button has been led to pins with a 2.54 mm raster together with GND reference pins, which allows the board to be used to control other modules with digital inputs, eg DFPlayer Mini or Voice Recorder without additional adapters. In addition, the buttons together with appropriately selected resistors form a matrix that can be connected to the analog pin of the microcontroller. The set includes dedicated caps to facilitate the use of the keyboard. Full documentation with application examples is available on the product wiki page.
