TP-Link WR703N Expander - Open Source Hardware

Developed in conjunction with the Sydney Hackerspace
Robots and Dinosaurs Inc June 2012
(featured on Hack A Day 24th June 2012)

This project is a small USB Hub & FTDI dual serial/GPIO/JTAG adapter.
It was designed to match the form factor of the TP-LINK WR703N router, but can be used with almost any USB host.
If you haven't used the WR703N - it is a great little OpenWRT box, made even better with the I/O expansion from this board.

How To Get One

As of June 2012, we now have some commercially made PCB's of the V1 design. Kean is populating them with the SMD parts when he has time.>
They will be available at cost ($20) to R+D members, or same + shipping to other Aussie hackerspace members. (WR703N and enclosure not included)

I get weekly enquiries about these PCB's, but I don't have the time or funds to do another production run.
If you'd like to see these boards available for sale worldwide, please vote for them at the Seeed Studios Wish page
