This board contains the following hardware:
- 1x Infineon (Cypress) CY7C65632 4-Port USB 2.0 Hub
- 2 ports are available externally, 2 ports are connected internally
- 1x FT232H Multi-Protocol USB Serial Adapter
- It's connected to a number of different data lines via 4-to-1 multiplexer ICs.
- 1x Infineon (Cypress) CY7C65211 USB to SPI/I2C/UART adapter
- This is connected to a number of different data lines via 4-to-1 multiplexer ICs.
- 1x Infineon (Cypress) FX2LP USB Microcontroller
- This is programmed with Sigrok FX2LAFW firmware to turn it into an inexpensive plug-and-play logic analyzer
- 1x MicroSD card slot

- 1x Power USB Port (designed to be connected to a power source like a travel charger, data lines not hooked up)
- 1x Data USB Port (designed to be connected to a test runner machine, potentially a single board computer without too much power)

*Note: I swear I'm not sponsored by Infineon or anything, it just so happened that their chips were the best fit for everything I needed on the board. I even tried to use an FT232H in the first rev of the hardware, but I could not for the life of me get it to work.*

It can test up to 10 different types of IO:
