Sobre este producto
- **Product Description:** The CH343P USB to TTL/UART module is a high-performance USB to serial converter for microcontroller debugging and programming. It supports 3.3V-5V power supply, USB 2.0 full-speed interface, and 50bps-6Mbps baud rate with automatic recognition up to 115200bps. Key features include: - Adjustable TTL levels (1.8V-5V) via VIO pin - Hardware flow control (RTS/CTS) and RS485 direction control (TNOW) - Wide operating temperature (-40°C to +85°C) - 17mm × 15mm compact size with standard mounting holes Pin functions: - VCC: 5V or 3.3V-5V DC input - GND: System ground - TXD: Data output - RXD: Data input - VIO: Level selection - RTS/CTS: Flow control - DTR/TNOW: Direction control (RS485) Common issues: Q1: Device not recognized? Ensure correct driver installed (CH343, not CH340). Q2: "Invalid head of packet"? Reduce baud rate to 115200bps. Q3: RS485 data error? Check TNOW pull-down resistor and common voltage. Q4: 3.3V system instability? Connect VIO to 3.3V or use 220Ω resistor on TXD/RXD.
