| Function: | Provide 40 GPIOs, accessible via I2C. |
|---|---|
| Key Chips: | NXP PCA9505 |
| External Ports: | 40x GPIO |
| Required Pins: | A4 (I2C SDA), A5 (I2C SCL) |
| Optional Pins: | D2, D3 (Interrupts) |
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
- 2011-10-18: First board assembled, but no time to test today.
- 2011-10-13: PCBs and parts received.
- 2011-10-09: Parts ordered, still awaiting PCBs.
- 2011-09-18: Completed/tagged rev. 1 and submitted to Laen.
- 2011-09-17: Forked HackTrack Shield to create IOstrich, completed changes to schematic, completely redesigned PCB layout, and BOM is now on file at Digikey. Will do the final checklist review and submit to Laen tomorrow.
