Black Swift is a Tiny OpenWRT Wi-Fi Board Powered by Atheros AR9331 (Crowdfunding)
In case you thought there were not enough Wi-Fi board in the market already, here’s another one with Black Swift. The board runs OpenWRT, is a little larger than Vocore, and quite smaller than WRTnode, is powered by Atheros AR9331, provides access to I/Os via headers, and comes with two micro USB ports which should make it easy to use, and allow some interesting applications with USB devices.
- SoC – Qualcomm Atheros AR9331 32-bit MIPS 24K CPU core @ 400 MHz, or 200 MHz in energy-saving mode selectable by software
- System Memory – 64 MB DDR2 SDRAM
- Storage – 16 MB NOR flash
- Connectivity – 802.11 b/g/n Wi-Fi (1×1, up to 150 Mbps) with PCB antenna
- USB – 1 x microUSB for power, 1x microUSB 2.0 port
- Expansion – Headers for 26x GPIO, 2x Fast Ethernet, SPI, I²C, 1x 16550 UART, 1x USB 2.0
- Misc – Factory reset button
- Power Supply
- 5 V (with full USB support), 3.3 V (w/o USB power), 3.4…6 V (using onboard voltage regulator, w/o USB power)
- Integrated voltage regulators: 3.3 V (switching mode, 1 A max, at least 700 mA available for powering external devices), 2.75 V (linear LDO, 300 mA max)
- Power consumption: 120 mA typical (400 MHz CPU frequency, Wi-Fi enabled), 60 mA in energy-saving mode (200 MHz, Wi-Fi disabled), 300 mA max
- I/O Voltage / Current – 3.3 V max (5V non-tolerant), maximum load 24 mA
- Dimensions – 25x35x4 mm
- Weight – 3 g
The board runs OpenWRT 14.07 Barrier Breaker, and will allegedly be open source hardware with schematics, Gerber files, and BoM released once development is complete. The company will also release OpenWRT patchsets, and utilities they developed for the board.
- A network music player with a Sound Blaster audio card connected to the USB port via a USB OTG adapter, which can be controlled with MPDroid on Android, QMPDClient on PC, or other MPD compliant clients.
- A Christmas tree lights controller. A little out of season, but it shows the GPIO capabilities of the board with several Betlux’s BL-FL7600 ultrabright LEDs, and a L293 quadruple H-bridge driver.
- An electricity meter (pictured on the right) to show a more professional use of the board. Power measurement is done via Analog Devices ADE7757 chip with frequency output.
You can have a look at these demos, right after the product introduction in the video below.
The project is on Kickstarter trying to raise $33,000 NZD (about $24,700 US) to fund mass production. There are three version of the board / kits available:
- Black Swift Basic – $35 NZD pledge (~$26 US)
- Black Swift PRO with on-board USB-UART adapter, and an extra baseboard (1.27mm to 2.54 mm header adapter) – $42 NZD pledge (~$34 US)
