## Description

The E1115 PS/2 Keyboard to ASCII Converter is a single chip solution dedicated to producing a single TTL ASCII character on the "press" of a keystroke. It is designed to offload the process intensive complex keyboard decoding of PS/2, allowing the host microcontroller to better allocate its resources. The output is a selectable TTL serial or a clocked serial data with interrupt signal.
 
 Plug in a PS/2 Keyboard in one end, and you can type away, with 57.6K or 115.2Kbaud (pin-selectable) TTL spit out of the TX pin. This can make adding a UI much easier for many projects where you can't sit around and wait for the interrupts from the keyboard port. **New! As of 4/10/13 the module also supports Adafruit's Magstripe and Barcode PS/2 readers**Please note that Adafruit have tested it and it does not work with Adafruit's PS/2 Touchpad.
 
 Comes as a ready-to-go pre-soldered and tested module
