From Orcboard

The uOrc board provides interfaces to motors, sensors, and various expansion boards. It has its own 32-bit ARM CPU running at 50MHz, giving it enough computational power to handle many tasks by itself. More typically, the uOrc is controlled from a small computer (like a laptop) via an ethernet interface.

• 50MHz ARM CortexM3 Microcontroller (Luminary LM3S8962)
  • 64KB SRAM
  • 256KB Single-cycle FLASH
  • Real-time kernel
• 100bT Ethernet
• 3 High-current H-bridges with braking, open-circuit, and current sensing. These can be used to control (among other things) bi-directional brushed DC motors.
• 2 quadrature phase decoders
• 8 14-bit digital-to-analog converters
• 8 "Flexible" digital I/O pins. Currently implemented:
  • Servo control (for Futaba-style servos)
  • Digital in (very low latency)
  • Digital out (very low latency)
• 8 "Dumb" digital I/O pins, ideal for bump sensing and lower bandwidth applications.
• Dedicated emergency stop input
• I2C expansion bus
• SPI expansion bus
• Optional serial-to-USB adapter
• Optional CAN bus interface
