USB to Serial Converter Home Made without Microcontroller IC - No need programming

USB to Serial converter home made without IC microcontroller or no need programming can realization using special IC for that. It is TF 232 BM. For more explanation will shown in this circuit: At the PC side you need driver software (winxp and lower) but for win7 up no need driver. Complete Circuit/Driver/Schematic can download at HERE Most of today's PCs and notebooks began to leave the serial port and switch to USB. The use of USB is more practical because in addition to its speed higher, this port has a 5 volt voltage source that can be used to provide resources on an electronic system that is connected...
