This is an ARM dev board in a 'DIP' form factor! If you're ready to graduate to 32-bit microcontrollers, this is a great entry.
The board is build on the MBed platform offering ease of development.
LPC1114FN28 Pinout:
The LPC1114FN28 is an ARM Cortex-M0 based, mbed-enabled microcontroller, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.
It is made particularly unique by the fact that it is available in a 28-pin dual-in-line package, making it perfect for breadboarding. You can develop a software by mbed, LPCXpresso, MDK-ARM, etc.
This device comes with no firmware installed, you may follow these procedures to program firmware onto the device.
You can use it in the same way as other mbed devices through a Micro-B USB cable.
