Measure voltage

is there a way to externally measure the vccaux and vccio values on the cw305

follow up - if sw5 is turned “off” does that mean that the fpga is not receiving power from vcc aux and vcc io or is it just vcc int

You can measure VCC-AUX off of JP8 or TP11 and VCCIO off of TP10. VCC-AUX and VCCIO should both be off if SW5 is off.
