General Description

MA101 is a driver free USB Data Bridge. It has internal built in UART protocol, SPI master, Two Wire Serial Interface master, GPIO read/write and 3 LED lights which show hardware activities. It also supports external EEPROM connection that can be customized for VID, PID, DID and other Strings. Megawin provides a library in Window environment that makes user to handle MA101 easily.
