This is an ARM Cortex-M0 microcontroller/processor and an interface card that plugs into a breadboard for direct prototyping. Get started with ARM embedded programming.
The configuration of the main board with headers will fit on three breadboards enabling a vast array of tie strips for use in prototyping. The board is completely soldered, so you can simply plug this board into the breadboard and start prototyping.
This particular ARM processor has the following specifications:32-bit of data bus width, maximum clock frequency of 48 MHz, 64 kB of Program Memory, 8 kB of RAM (SRAM), Analog to Digital precision is 12-bits, will accept voltages of 2.4v to 3.3v (3.3 volts is typical), package of the processor itself is 64 LQFP (Low profile Quad Flat Pack), 16 analog to digital channels, contains 55 I/O pins and 7 timers.
