FT232 driver download link: https://pan.baidu.com/s/1x9Zwpr35d-R0rPVFrg7cAw FT232R Introduction: With the development of computer technology, parallel and serial ports are slowly disappearing from PCs, and now even desktops have fewer parallel ports. But for engineers, both parallel and serial ports are essential interfaces, especially the serial port. For the computer without a serial port, the most convenient solution is to use the USB to serial chip to virtualise a serial port out of many manufacturers have produced such a chip, such as silicon LABS CP210x series, TI’s TUSB3410, Nanjing Qinheng CH34x series, FTDI FT232 series, Prolific’s PL230x series, Aike’s ARK34x series, FTDI FT232 series, FTDI FT232 series, Prolific’s PL230x series. series, Prolific’s PL230x series, ARK3116 series, and so on. From the stability point of view, it is the FT232 series that is the most reliable, and you can use it to debug the programme without worrying about the blue screen. Features: The FT232R is a USB to serial UART interface A low-cost way to add USB capability to Arduino or other microcontrollers. Use this to give your own breadboard Arduino USB capability for bootloading or downloading sketches. FTDI FT232RL USB to TTL Serial Converter Adapter Module 5V and 3.3V For Arduino RXD/TXD transceiver communication indicator Includes over-current protection, using a 500mA self-restoring fuse This board includes a DTR pin needed to auto-reset Arduino when downloading to your device. Using USB2.0 the best FT232RL chip, USB power supply using 500MA fuse (FUSE) to protect your USB power supply and equipment, more stable performance; FT232RL USB to Serial Module USB to TTL level, USB2TTL protection version supports overcurrent protection version; This product uses a new design, the use of USB 2.0 FT232RL chip, the USB into a serial port. With two power versions; Each module in the factory using self-receiving 10W byte test passed; Upgrade TYPE-C interface power supply, support 3.3V 5V downloader burner line, optional 5V or 3.3V interface level.
