USB to Serial Port Module High-Speed USB to UART (TTL) Adapter for Connecting to Encryption/Decryption Module Configuration Port
Product Description: &nbsp; This product is a high-performance USB to TTL serial communication module based on the CH340 chip solution, enabling &nbsp; USB to serial communication functionality. It is widely used for debugging microcontrollers and communication between host computers. &nbsp;
Product Features: &nbsp; High compatibility: Supports Windows, Linux, and macOS systems, with automatic detection of COM ports. &nbsp; High-speed transmission: Supports a maximum baud rate of 2,000,000 bps. Plug-and-play: Powered via USB. Reverse-plug prevention design: The serial port end uses a reverse-plug prevention connector to prevent incorrect connection of TX and RX. Product dimensions: 30&times;20mm
Usage Steps: 1. Driver installation: Insert into the computer's USB port and install the CH340 driver. 2. Wiring: Connect the module's GND/TXD/RXD to the target device correctly. 3. Serial port debugging: Open the serial port assistant tool or host software, select the corresponding COM port and baud rate.
Notes: &nbsp; 1. Pay attention to the wiring order of the serial port's TX and RX. The RX/TX of this product must be cross-connected with the target device's RX/TX. &nbsp; 2. For long-distance communication, it is recommended to reduce the baud rate to improve stability. &nbsp;
Common Issues and Solutions: &nbsp; 1. Computer cannot recognise the COM port &nbsp; &rarr; Check if the driver is installed correctly, or try using a different USB port. &nbsp; 2. Communication data is garbled &nbsp; &rarr; Ensure that the baud rate, data bits, and stop bits are set consistently on both sides. &nbsp;
Specifications: &nbsp; Name: USB to Serial Port Module &nbsp; Material: PCB &nbsp; Model: AL-371-2 &nbsp; Operating Temperature Range: -40&deg;C to +60&deg;C Product Dimensions: 3 x 2 cm &nbsp; Packaging Dimensions: 75 mm x 75 mm x 30 mm &nbsp; Weight: 16 g &nbsp;
