xQFP protoboard free PCB build

Saturday, December 31st, 2011

Juan used his free 0.50mm Dangerous xQFP protoboard to get started with a MSP430F5510. The protoboard is designed to get you up and running with a new surface mount microcontroller. We're super proud of this board, it's something we use all the time to develop our own projects. Currently available in...
