The breadbee is a very small, 32mm x 30mm, ARM Cortex A7 development board based on a relatively unknown IP camera SoC, the MSC313E, from a company called MStar. You might have never heard of MStar but you probably have one of their chips in your TV. With a small adapter socket it can be mounted vertically in a standard breadboard.

Features:

• ARM Cortex A7 @ ~1GHz
• 64MB DDR2
• 16MB SPI-NOR flash
• 100Mb Ethernet
• USB2
• SD/SDIO
• SPI
• I2C
• ADC
