USB TTL Serial Adapter Module 3.3V 5.5V Mini Port

USB TTL Serial Adapter Module 3.3V 5.5V Mini Port Description

USB power with overcurrent protection: 500MA selfrestore fuse protects the USB power line and automatically resets after a fault, helping prevent damage to the host computer and connected devices. Pinout: DTR, RXD, TXD, VCC, CTS, GND for straightforward wiring and compatibility with common USBtoserial configurations. Benefits and features Safe USB power: overcurrent protection with a 500MA selfrestore fuse reduces the risk of shorts and electrical damage. Clear pin definitions: standard DTR, RXD, TXD, VCC, CTS, and GND pins simplify integration with microcontrollers and serial modules. Compact design: suitable for inclusion in small development boards and projects. Reliable data and control lines: supports typical serial communication requirements through RXD, TXD, DTR, and CTS, with VCC and GND for power. Compatibility Works with standard USBtoserial adapters and common microcontroller development boards that use DTR, RXD, TXD, CTS, VCC, and GND signals. Use scenarios Microcontroller programming and debugging: connect to Arduino, ESP, or similar boards to provide data lines (RXD/TXD), control lines (DTR/CTS), and USB power (VCC/GND) with overcurrent protection. Development and testing of USBpowered modules: use the serial lines for configuration, monitoring, and data exchange while benefiting from power protection on the USB supply. Prototyping with safe USB power: power small peripherals from USB while protecting both device and host during testing and iteration.
