![]() | E field Touch Keyboard The E-Field Touch Keyboard eliminates mechanical keyboard switches. Two thin, triangular electrodes are connected together to form a matrix of nine columns and four rows. The electrodes sense the presence of finger near a particular key, and send a signal to the e-field sensor board. The MC68HC908QY4 MCU decodes and identifies the key and sends the data to the PC either as a PS/2-compatible signal or serial signal. |
