Keyboard equipped with two colored buttons. Keyboard leads are made in the form of a connection tape ended with a3-pinfemale connector with a2.54 mmraster. The connector located at the end of the tape significantly facilitates the process of connecting the keyboard to the main module, e.g. Arduino. To make such a connection we can useconnecting cables orgoldpinconnectors with a 2.54 mm raster. Additionally, on the back of the keyboard there isa self-adhesive tape, which allows to easily attach the keyboard in any place.
The length of the tape connecting the keyboard to the module is 90 mm.
