This breakout board for the FTDI FT232RL USB to serial converter, has been designed to work with standard TTL UART interfaces. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. The operating voltage can be selected between 3.3V and 5V via a 2-pin jumper.
This board is supplied with one set of male and one set of female connectors – these need to be soldered as required.
The marked pin is the GND pin (Also Marked as BLK on other breakouts), the pin out is :
GND (marked with ] on the board)
5V/3.3V (Selected using the voltage select jumper)
