tommielauriks Usbstandards are wicket bad, it is not just you. Blame Apple mostly but all are guilty. More plugs, more money, it is wild. Anyway, this one is called usb mini, was "the" solution for all phones, until replaced because it was not flat enough.

mk_glover The board is self explanatory and is designed to be powered from the USB interface. It uses an FTDI FT232RL USB to UART chip with TTL levels on the serial interface. The datasheet for the chip is is available on the FTDI website.:- DS_FT232R.pdf. However, the board and chip does support being powered by a +3.3V to +5.25V supply on the "5V" hole for the device core. This is the Vcc pin of the chip. Now, the hole labelled "VCC" is connected to the VCCIO pin of the FTDI device and in the words of FTDI:- "+1.8V to +5.25V supply to the UART Interface and CBUS group pins (1...3, 5, 6, 9...14, 22, 23). In USB bus powered designs connect this pin to 3V3OUT pin to drive out at +3.3V levels, or connect to VCC to drive out at 5V CMOS level. This pin can also be supplied with an external +1.8V to +2.8V supply in order to drive outputs at lower levels. It should be noted that in this case this supply should originate from the same source as the supply to VCC. This means that in bus powered designs a regulator which is supplied by the +5V on the USB bus should be used." Care may be required for supply isolation in your application.

ApoMar actuallyis very simple,on each side is a HV and an LV,on the HV side goes 5v and on the LV side the 3,3V, H-High,L-Low,tx to tx and rx to rx,on each side
