Design and Construction
The USB to TTL Serial Converter Module is designed with a compact PCB layout and a double-sided SSOP packaged IC, providing a practical interface for both hobbyist and professional electronics applications.
A convenient pin header output allows the module to be connected directly to compatible microcontroller boards and embedded devices. The module also provides access to the available IC output pins, allowing advanced users to integrate additional functions into custom circuits.
The 3.3V/5V dual-voltage support makes the module suitable for different TTL logic systems. Users can select the appropriate voltage level according to the requirements of the connected device.
The integrated TX and RX LEDs provide immediate visual feedback during serial data transmission and reception. The onboard 500mA fuse provides additional protection for the USB interface in case of a short circuit.
Working Principle
The module acts as a bridge between a computer’s USB interface and a device’s TTL UART serial interface.
When connected to a computer through the Micro USB port, the converter translates USB data into TTL-level serial signals. These signals can then be transmitted to a compatible microcontroller or embedded device through the UART pins.
During communication, the TX LED indicates transmitted data and the RX LED indicates received data, making it easier to monitor serial activity.
The module supports both 3.3V and 5V logic levels, allowing it to communicate with compatible devices operating at either voltage.
Pin Header and Connections
The pin header provides convenient access for connecting the converter to compatible devices. Typical UART connections include:
- VCC – Power supply
- GND – Ground
- TXD – Serial transmit
- RXD – Serial receive
For normal UART communication, connect the converter’s TXD to the target device’s RXD and the converter’s RXD to the target device’s TXD, along with a common GND connection.
Always verify the target device’s voltage and pin configuration before making connections.
