This is a new gadgeteer mainboard from Micromint. It uses the LPC43xx chip, which includes dual cores, an M4 for NETMF and M0 for possible native work. The company lists this as open-source so we look forward to messing with the code.
Well done Micromint and we look forward to seeing more offers from you and others, those who truly believe in Gadgeteer. Live long gadgeteer
