[Squonk] is rather famous in the world of repurposed routers, having reverse engineered the TL-WR703N wireless router from TP-Link a few years ago. With that knowledge, he’s developed an open platform for Things on the Internet called Domino. It’s pretty much exactly what you would get by cracking open a router bought on AliBaba, only in a much more convenient package with many more pins broken out.
The Domino builds on [Squonk]’s reverse engineering efforts of the TP-Link TL-WR703N wireless router, the router that has stolen the thunder from the Linksys WRT54G for all those sweet, sweet, embedded hacks. Both the 703N and the Domino are built around the Atheros AR9331. While the router version of this chipset only breaks out a few GPIOs and other interesting pins, the Domino breaks out just about everything – GPIO, JTAG, I2S, UART, SPI, USB, and Ethernet can be found on the device.
The basic Domino can hopefully be had with a $25 pledge to the Kickstarter campaign. That’s a little less than the normal price for a WR-703N, and if you’re putting a router in a hat it might be worth your while. There are a few advanced versions that include an ATMega32u4 microcontroller, making it compatible with the Arduino Yun as well.
