 Note
Pleasetakenoteofthefollowingpowersupplyopons:
ThesimplestwayistoplugaUSBcableintotheUSBportonthePYBD.Thatwill
powerthePYBDandallowcommunicaonwiththePC.
YoucanpowerthePYBDviatheVUSBport(seeX‑posions).Thevoltageonthis
portmustbebetween4.8Vand5.2V.Thisportcontainsaprotecvediodeanda
1Afast/0.22Ohmfuse.
YoucanpowerthePYBDviatheVINport(seeY‑posions).Thevoltageonthis
portmustbebetween3.2Vand4.8V.
The3V3pinisoutputonlyandshouldnotbeusedtopowertheboard.Itcanbeusedasa
