PIC32MX1 and PIC32MX2 are the families of microcontrollers recently introduced by Microchip. These are the cropped down members of PIC32MX3/4/5/6/7 MCUs with lesser power (40MIPS) and lower number of pins. The chips host the same M4K core but with smaller program and data memories.
This all free, open source, very small (1.5″x2.0″) and simple board is an attempt to introduce a ready to use board for easy prototyping. It has a small SOIC-28 PIC32MX1 MCU. SOIC-28 is chosen because it’s easier to solder. The breakout pins can be soldered with standard 0.1″ male/female header to be easily used with veroboard or breadboard. Diptrace source files, a schematic in PDF format and Gerbers are there to download.

The ICSP header connector on the board is tall and not reverse protected. Would be nice to replace it by the same 2×10 pin mini-connector used for the new Cortex Debug connector, or course carrying different signals as we are in the MIPS32 world here. Need to create and attach the corresponding adapter on the ICD3 modular terminal. A risk is that later on, Microchip introduces a different, official signal layout on the 2×10 pin mini-connector.

The ICSP is pickit3 styled which is widely used in the PIC world. Since the tools of PIC and Stellaris (Cortex) are different, may be it will not be much beneficial to keep the same type of connectors.
