FT232RL 3.3V 5.5V FTDI USB to TTL Serial Adapter Module for Arduino Mini Port

The FT232RL USB to TTL Serial Adapter Module is a compact and reliable breakout board based on the FTDI FT232RL USB-to-serial IC. It is designed for easy programming and communication with official Arduino boards, Arduino Mini, and 5V-compatible Arduino clones. The board is also suitable for a wide range of general serial applications. Unlike standard FTDI cables, this module features a DTR (Data Terminal Ready) pin instead of an RTS pin. This enables an Arduino target board to automatically reset when uploading a new sketch — eliminating the need to manually press the reset button. Any Arduino board with a reset pin brought out to a 6-pin connector can benefit from this convenient auto-reset function.
