Power Measurements (See Appendix B, "ECP5 Power" sheet)
The ECP5 PCI Express Board allows for easy power measurements with a multi-meter of the ECP5 device. The
ECP5 power rails are isolated and can be measured by measuring the voltage across power resistors.

PMOD (See Appendix B, "ECP5 Config" sheet)
The ECP5 connects to a PMOD connector J3. To isolate the PVMOD connector from the FTDI device set all SW5
switches to 1 (Up=1).
