Part 7.3: Expansion Port J11

The expansion port J11 is a 40-pin 0.1 inch double-row connector, which
expands more peripherals and interfaces for users.
the user can solder to a double-row male connectors or female connectors as
needed. The J11 interface can be directly connected to the module provided by
ALINX. The expansion port J11, which expands more peripherals and
interfaces for users. Currently, the J11 interface can be directly connected to
the module provided by ALINX, include: ADDA module, LCD module, Gigabit
Ethernet module, audio input/output module, matrix keyboard module, 500W
binocular vision camera module, etc.
The expansion port has 40 signals, of which 1-channel 5V power supply,
2-channel 3.3 V power supply, 3-channle ground and 34 IOs. 34 IO ports are
connected to BANK34 and BANK35 of ZYNQ PL. The PCB design is
differentially connected. The default level is 3.3V. The user can change the
level of IO by replacing the power chip (SPX3819M5-3-3) of VCCIO34 and
VCCIO35 on the core board.
Do not directly connect the IO directly to the 5V device to avoid
burning the FPGA. If you want to connect 5V equipment, you need to
connect level conversion chip.
The circuit of the expansion port (J11) is shown in Figure 7-5:
