SparkFun FT231X Breakout Kit is designed to get started with FTDI and features a UART hardware handshake. The pin-outs included in this breakout board match the FTDI cable to work with official Arduino and cloned Arduino boards. The FT231X kit features the DTR pin to allow an Arduino target to auto-reset when a new Sketch is downloaded. This kit features a jumper on the back that allows the VCC output to be configured to either 3.3V or 5V. The FT231X kit operates at 3.3V maximum input that can operate down to 1.8V with external pull-ups and is also 5V tolerant. This breakout kit includes a 0.8m reversible USB-A to Micro-B cable and a 40-pin strip of male breakaway headers.
