Domino Pi Hardware
Overview
Domino Pi is a low-cost, compact OpenWRT-based 802.11 bgn WiFi development board based on Qualcomm/Atheros AR9331 WiSoC.
The Domino Pi board extends the Domino Core module by adding the following features:
- Integrated USB<->UART bridge for serial port (default to U-Boot / Linux console)
- Integrated +5 V input / +3.3 V output, 2 A DC/DC power supply
- Integrated 2.4 GHz WiFi PCB antenna
- Integrated Jumpstart push button
- Integrated Power and Wireless LEDs
- Integrated 2x 28 pin, 2.54 mm pitch headers
The dual edge headers provide:
- USB 2.0 (host or slave)
- 2 x 10/100MB Ethernet ports
- SPI (MOSI, MISO, CLK, CS)
- I2S (CK, WS, SD, MCK, MICIN)
- SLIC
- SPDIF Output
- JTAG (TMS, TCK, TDI, TDO)
- 9x LEDs (also used for bootstrap settings)
- Up to 29 x GPIOs (multiplexed with other functions above)
