User PMOD GPIO Headers
[
, callout 26]
The ZC706 evaluation board GPIO 2 x 6 male headers J57 and J58 support Digilent Pmod
Peripheral Modules. J57 pins (IIC_PMOD_[0:7]) are connected to the TI TCA6416APWR I2C
expansion port device U16. J58 pins (PMOD1_[0:7]) are connected to the TI TXS0108E
3.3V-to-VADJ level-shifter U40.
See the Digilent website for information on Digilent Pmod Peripheral Modules
.
Information about the TCA641APWR and TXS0108E devices is available at the Texas
Instruments website
.
