I haven't used it, but I read the docs at the site, http://www.xkeys.com .
The main operating mode "memory resident" makes multicharacter
strings available at every key position, recorded in EEPROM onboard.
The board doesn' t include any protection circuitry for the microprocessor,
so static electricity precautions certainly should be used.
Because there are no driver/receivers on the board, the keys would best
be put in the same case as the board.
USB is designed to work out to 30 feet. I got a webcam to work
correctly out to 40 feet. Best to use low-capacitance USB cable if you
string it up far from your computer.
