This programmer uses the FTDI FT232RL USB-to-Serial converter chip. The pinout of this board matches the FTDI cable and works with official and cloned Arduino boards like Lilypad, ProMini, and micro-controllers like ATmega328, ATtiny etc. This board brings out the DTR pin as opposed to the RTS pin as in the FTDI cable. When a new sketch is being downloaded, the DTR pin allows the Arduino target chip to auto-reset which is a nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to the 6-pin connector.
The pin labels BLK and GRN correspond to the colored wires on an FTDI cable. The black wire of cable is GND, and green is CTS. This helps in aligning the module with the Arduino target chip. This board has TX and RX LEDs to help you to observe and verify the serial traffic, making it better to use than the FTDI cable.
This board decrease the cost of Arduino development and increases ease of use. The jumper on the back of the board allows the board's power output and IO level to be configured to either 3.3V or 5V.You can cut the default 5V trace and add a solder jumper to switch to 3.3V.
