Ai-Thinker CP2102

USB-T1 is a USB-to-TTL module based on the high-performance CP2102 chip, supporting communication rates up to 2Mbps. The module offers exceptional compatibility with Windows, MacOS, and Linux systems, supporting both X86 and X64 architectures. Its TTL level is compatible with the 3V3 standard, and it features onboard 5V, 3.3V, and 4.2V power output pins for powering MCU systems. DTR/RTS output interfaces are also retained, allowing software control of these two pins' logic levels via the serial port to automatically trigger reset during firmware download on certain MCUs. The module is equipped with dual-color LED indicators — red and blue LEDs display the operating status, with TX and RX LEDs flashing during data transmission for clear visibility of transfer activity. Additionally, a 3V3/4V2 output selection switch is included: by default, the Vo pin outputs 3.3V; shorting the 3V3/4V2 jumper switches the Vo pin output to 4.2V, while the 5V pin always outputs 5V directly.
