2pcs CP2104 USB 2.0 to TTL UART Module Serial Converter STC Programmer Adapter Board Replace CP2102 for Serial Debugging

High performance CP2104 chip: This module uses the CP2104 USB-UUART bridge, which has higher stability, lower power consumption, and faster data throughput compared to the old CP2102 solution. Very suitable for reliable serial communication in development and testing environments. USB 2.0 to TTL UART interface: Supports standard USB 2.0 interface, used for connecting PCs, laptops, and single board computers. Provide TTL level UART interface for direct connection to microcontrollers, development boards, and embedded systems. 6-pin output design: featuring a convenient 6-pin head layout, typically including TXD, RXD, GND, VCC, and control signals (such as DTR/RTS) for flexible wiring. The clear pin arrangement simplifies integration with various projects and programmers. CP2102 module replacement: designed as an upgraded replacement for CP2102 USB to TTL module. Provide better performance and enhanced compatibility while maintaining similar appearance and connectivity, making it easy to switch to existing settings. Wide application range: very suitable for serial debugging, firmware download, MCU programming, and communication with routers, modems, and other UART based devices. Suitable for hobbyists, manufacturers, engineers, and students engaged in electronic projects.
