What is it?
It is Matrix Orbital's newest & compact economy serial interface module called the "X-board S-Series". It was designed as a daughterboard to receive serial communication and display this data on an LCD, VFD or PLED. Add it easily to any alphanumeric parallel display and you will be up and running in no time. It is the same board that is used in our all of our MOS series products.
