ThatmodulecanofcoursebeUSBpoweredandtheinternalvoltageregulatordelivers3.3VfortheexternalIC's. USB Bus-powered: 1) Connect VBUS to VCC (CN3, pin 1 to CN3, pin 3). This connection takes the power from the USB bus (VBUS) and connects it to the voltage regulator input on the FT4232H Mini Module. The voltage regulator, in turn, provides V3V3, VPLL and VUSB power inputs to the FT4232H chip. 2) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22). This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT4232H chip.Oncethemoduleiscorrectlywired,itcanbeconnectedtoaPCandnormallyitwouldinstallthedriverswithoutanyproblem.Therearetwosideplugs(2X26pin)thatallowstheusertoconnectwhateverhewantdependingupontheapplication.IfyoudonotwanttoetchaPCB,youhavetouseabreadboard(copperaroundeachhole)easytofindinanelectronicshop.Asyoucanseeonthesecondpicture,theonlythingtodoistosolder2female26pinconnectorsinordertopluginthemoduleandoneconnectorforyourjtagconnection.(DependsuponyourSTBconfiguration,14pin,20pin...)(Ifyouwantyoumayevensolderthe2X26pinplugsifit'stoodifficulttofindthefemaleconnectors.)Therestofthejobistowiretheconnectionsbetweenthemoduleandthejtagconnector.Notverydifficult:thereare16wirestosolderonmy
