chipKIT® MZ Lite
The chipKIT MZ Lite is a cut-down version of the chipKIT Pro MZ. It features a lower power voltage regulator and a main MCU with less memory. Apart from that the only other differences are cosmetic. You still get the SD card slot. You still get a 200MHz microcontroller with FPU. You still get the native USB interface. You just don't have as much flash and SRAM. But that means that it's cheaper than the Pro MZ.
The board layout and pin arrangement is modelled on the popular Fubarino SD.
