The IOstrich will provide 40 GPIOs, based on the HackTrack Shield. Up to 8 of these shields can (theoretically) be stacked on one Arduino, giving a total of 320 added-on GPIOs. The shield can be used in either 3.3v or 5v mode, and is 5v-tolerant in both modes.
Project Status
- 2012-01-29: Assembled first few shields, released as Strich Labs SHLD-0003!
- 2012-01-22: Ordered connectors from 4U. Completed all documentation and final library code, set up a github project for it and created product info pages on Strich Labs' site.

- 2012-01-06: Boards received, first one assembled (s/n 0010), passes all tests OK. Will order parts for the rest of the production run when I get back from CA. Also need to take photos of the board for the site.
- 2011-12-27: Library complete and tested against real hardware. Production boards ordered from MyRO. Parts ordered for two assemblies from Digikey.
- 2011-12-26: Finished library (implemented pin inversion and interrupt-on-change), still needs testing against hardware (that is at the lab right now).
- 2011-12-25: Library bug fixed, self-test code written, existing board passes self-test.
