Ready to Use CH340 USB to TTL UART Serial Convertor Module for PCBs

The Ready to Use CH340 USB to TTL UART Serial Convertor Module for PCBs is an electronic component designed to facilitate communication between a computer's USB port and microcontroller-based circuits or other devices that use TTL (Transistor-Transistor Logic) serial communication. The module is particularly useful for programming, debugging, and interfacing with embedded systems.

Specifications of Ready to Use CH340 USB to TTL UART Serial Convertor Module for PCBs

• PCB size: 14.86mm*11.5mm
• PCB color: black immersion gold board
• Supported OS: Adopt the new chip CH340E, support all operating systems on the market
• In pins: GND, D+, D-, VCC
• Out pins: GND, TX, RX, VCC
  The module input power supply is 3.3-5V, and the output is 5V by default. To change to 3.3V power supply, remove the 5V pad resistor and attach a 0R resistor to the 3.3V pad. The signal level is 3.3V.
