About this item

The FT232RL USB to TTL 5V/3.3V Serial Adapter Module is an essential tool for interfacing microcontrollers like Arduino Pro Mini with a computer via USB. Powered by the FTDI FT232RL chip, it ensures reliable USB-to-serial communication, making it ideal for programming and debugging embedded systems. This module offers flexible voltage support, allowing users to select between 5V and 3.3V logic levels through a jumper setting. This versatility accommodates a wide range of microcontrollers and sensors that operate at different voltage levels. Additionally, it includes a 500mA self-resetting fuse for overcurrent protection, safeguarding both the module and connected devices. For enhanced usability, the adapter features onboard LEDs that indicate power, data transmission (TX), and data reception (RX) activities, providing real-time feedback during operations. Its compact design, measuring approximately 36mm in length and 18mm in width, ensures easy integration into various projects. The module connects to devices via a mini USB port, facilitating straightforward connections without the need for additional drivers. Whether you're developing custom Arduino boards or working on serial communication projects, this FT232RL adapter module offers a cost-effective and efficient solution for seamless USB-to-TTL interfacing.
