There have been lots of cool new microcontroller boards coming out lately that look really nice for mobile robotics applications. Digi International is the latest with their announcement of a new microcontroller that has built-in WiFi support. The new single board computer is called the ConnectCore Wi-9C and is based on a 155 MHz NetSilicon NS9360 ARM9 CPU. The board includes 256MB of SDRAM and 256MB of Flash. There's plenty of I/O for connecting all those sensors your robot needs. It has 4 SPI ports, I2C, USB 2.0, 800x600 SVGA LCD controller port, 55 GPIO lines (7 high-current), 8 timers (or 4 PWM), 4 programmable interrupts, and four TTL serial ports, and 2 LEDs. And, of course, it includes the previously mentioned WiFi in the form of a pre-certified 802.11 a/b/g radio module. The whole thing is just 3 x 3.5 inches. It runs on 3.3v with an optional 5v requirement for the USB port. For more see the full specifications. The board will run the Linux 2.6 kernel and is supported by the GNU GCC tool chain.
