Board Component Descriptions
UART1 (MIO 20-21)
PS-side UART1 is accessed through the U151 FT4232HL USB-to-Quad-UART bridge CDBUS
port. The UART connections from XCZU7EV MPSoC U1 PS-side MIO 20 and 21 to the
FT4232HL device through level-shifter U161 are listed in
.
CAN1 (MIO 24-25)
The PS-side CAN bus TX (MIO24, U1 pin E28) and RX (MIO25, U1 pin D29) signals are routed
through TXS0104E level-translator U33 and TI SN65HVD232 CAN-bus transceiver U122 to
the 0.1 inch centered 8-pin male header J98 as shown in
