Domino Qi Mini


Domino Qi Mini is a small-sized board that is a fully compatible derivative of the original Arduino YunTM, crammed into a tiny form factor.

Plug it onto the Domino Qi baseboard in order to be fully compatible with the ubiquitous ArduinoTM Shield form factor and benefit from hundreds of already existing shields for rapid prototyping.

Domino Qi Mini is a low-cost, compact OpenWRT-based 802.11 bgn WiFi board based on Qualcomm/Atheros AR9331 WiSoC and on the Atmel ATMega32U4 MCU. Communication between the 2 chips is achieved using an Arduino YunTM-compatible Bridge hardware and software library.

The Domino Qi Mini board extends the Domino Core module by adding the following features:

  • Atmel ATMega32U4 MCU
  • Arduino YunTM-compatible Bridge
  • +5 V input / +3.3 V output, 2 A DC/DC power supply
  • 2.4 GHz WiFi PCB antenna
  • 32U4 Reset, WLAN Reset and User push buttons
  • Power, Wireless, WAN and USB LEDs
  • 2x 22 pin, 2.54 mm pitch headers

The dual edge headers provide:

  • USB 2.0 (host or slave)
  • 1x 10/100MB Ethernet port
  • ATMega32U4 RESET pin
  • ATMega32U4 UART (TXD1, RXD1)
  • ATMega32U4 I2C (SDA, SCL)
  • ATMega32U4 digital (+ PWM) pins (D4-D6 and IO8-13)
  • ATmega Analog pins (A0-5 + AREF)
  • Arduino YunTM-compatible pins (HANDSHAKE, GP6)
  • +5V, +3.3V and GND power supply pins

Note: Domino is not connected to ArduinoTM and the Domino Qi Mini product is a derivative. Any technical support must be directed to us, not to ArduinoTM.
