Table 9.1. Arty S7 Shield Pinout
The pins connected directly to the FPGA can be used as general purpose inputs or outputs. These pins include the I2C, SPI, and general
purpose I/O pins. There are 200 Ohm series resistors between the FPGA and the digital I/O pins to help provide protection against
accidental short circuits (pins A10 and A11 instead have 140 Ohm series resistors). The absolute maximum and recommended operating
voltages for these pins are outlined in Table 9.1.1.
