This FT232RL USB to UART TTL-232R serial port cable uses the industrial-grade FT232RL chip to provide stable USB to TTL level conversion function. Supports 3.3V and 5V voltage output, and is compatible with mainstream development platforms such as , , and STM32. The wire is made of UL2464 AWG24 certified wire, with tinned copper core, which is fire-resistant and flame-retardant, and can work reliably in environments from -20°C to 80°C. The 4-core interface (TXD, RXD, GND, VCC) facilitates quick connection to a breadboard or pin header, and is suitable for firmware downloading, serial port debugging, se/n*/sor data collection and other scenarios. Available in various lengths of 1.8 meters, 3 meters, and 5 meters to meet different project needs.
