Explore M3 is a feature rich ARM Cortex M3 development board. It can help you prototype ideas faster with Arduino and take them beyond, with bare metal programming, RTOS support and lower power modes if need be. All the source-code and hardware design files are open-source including the on board boot-loader. This makes it easy in using the board/chip in your custom designs

Questions
How big is the ExploreM3 PCB?
It measures 25.5 × 62.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ExploreM3 use?
66 parts, built around the LPC1769FBD100 and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ExploreM3 KiCad files?
From the ExploreEmbedded/Explore-M3-Hardware-Design- repository on GitHub, at the commit this page was made from: the board is Hardware Design Files/ExploreM3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ExploreM3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
