Transform your Android phone or tablet into a powerful serial communication tool with our USB Type-C to Serial Port (TTL) Adapter. This compact and efficient module features the reliable CH340 chipset, enabling seamless UART communication, debugging, firmware flashing, and data logging directly from your mobile device. Perfect for engineers, developers, and hobbyists working with microcontrollers (Arduino, ESP8266, ESP32, STM32, etc.), industrial automation, and embedded systems.

Key Features

✅ USB Type-C to TTL Serial Conversion – Connects modern Android phones (with OTG support) to serial devices (3.3V or 5V TTL).
✅ CH340G Chipset – Stable and widely compatible with Windows, Linux, Android, and macOS (drivers required).
✅ Supports Multiple Baud Rates – From 300 bps up to 2Mbps for flexible communication.
✅ Built-in Voltage Protection – Prevents damage to connected devices with reverse polarity and overvoltage protection.
✅ Plug-and-Play – No external power needed (draws power from USB OTG).
✅ 4-Pin TTL Interface – Includes TX, RX, GND, and VCC (3.3V/5V selectable) pins for easy wiring.
✅ LED Indicators – TX/RX activity LEDs for real-time monitoring.
✅ Compact & Portable – Lightweight design for fieldwork and on-the-go debugging.

Compatibility

✔ Android Phones – Works with USB OTG-supported devices (Android 4.0+).
✔ Microcontrollers – Arduino, ESP8266, ESP32, Raspberry Pi, STM8/STM32, and more.
✔ Industrial Devices – PLCs, CNC machines, GPS modules, and legacy serial equipment.
✔ OS Support – Windows (CH340 driver needed), Linux (built-in), macOS (driver required).

Applications

• Firmware Flashing & Debugging – Upload code to MCUs without a PC.
