Two dev boards in one! This is the main training board used in our MPG Level 1 program, and is a tremendous platform for any experimenting you want to do with a high powered Atmel SAM3U2 ARM Cortex-M3 and a Nordic nRF51422 SoC with Cortex-M0 and ANT+ / BLE radio. It features a J-Link Onboard that allows full programming and debugging of both processors without any external tools. Most processor pins are available in the breakout, and there is a prototyping area built-in as well. Power comes from any 5V USB source through the included USB cable.
