Hello, thanks for buying our product, and welcome to Ufixers community.
Yes, you can use USB as power voltage for VCC and VCCq,
or by external DC power also allowed as long as it is still using standard rate power between 1.8 up to 3.3 v.
It also good to keep your jumper wire as short as possible, for maximum lenght is 6cm.
