Capabilities
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
