The Omega's Brain

The Omega's brain and central nervous system are provided by the Qualcomm Atheros AR9331 SoC.

With the SoC and on-board components, the Omega has the following:

  • 400 MHz MIPS 24Kc Big-Endian Processor
  • 64MB of DDR2 RAM running at 400 MHz
  • 16MB of on-board flash storage
  • Support for USB 2.0
  • Support for Ethernet at 100 Mbps
  • 802.11b/g/ WiFi at 150 Mbps
  • Connectivity
  • The Omega also has the following:
  • 18 digital GPIOs
  • A single Serial UART
  • Support for SPI
  • Support for I2S

  • Arduino compatible
  • Mini-dock

Low Power
The Docks receive 5V through the Micro-USB connector. The Docks also have regulators to provide the Omega with a constant 3.3V.

Through observation, we've found the following current draw on the Omega:

Dock Idle Current Draw Load Current Draw Peak Current Draw
Expansion Dock 120 mA 150 mA 180 mA
Mini Dock 170 mA 200 mA 220 mA
Arduino Dock 110 mA 140 mA 180 mA
