Board to Board Connectors CON3
The 80-pin connector CON3 is used to extend the normal IO of the
BANK15 and BANK16 of the FPGA. In addition, four JTAG signals are also
connected to the carrier board via the CON3 connector. The voltage standards
of BANK15 and BANK16 can be adjusted by an LDO chip. The default installed
LDO is 3.3V. If you want to output other standard levels, you can replace it with
