Overview

The TEL0070 is a versatile USB to serial bridge that supports multiple industrial communication standards including RS232, RS485, and TTL levels. Based on the CH340G chip, this module acts as a Swiss Army knife for serial debugging by providing four different interface modes through a single USB 2.0 connection.

Why Choose This Part

This module eliminates the need for separate converters by integrating RS232, RS485, and TTL on a single board. The use of the CH340G ensures broad driver compatibility across Windows, Linux, and macOS systems.

Applications

Industrial PLC Interfacing

Connect modern laptops to legacy industrial equipment using RS485 or RS232 protocols for programming and data logging.

MCU Debugging

Use the TTL 5V interface to monitor serial output and send commands to microcontrollers like Arduino and PIC.

Device Firmware Updates

Serve as a bridge for flashing firmware to embedded systems that lack native USB support.

RS485 Networking

Acts as a master node in a multi-drop RS485 network for sensor data acquisition.

Getting Started

Plug the module into a USB port and install the CH340 drivers if they are not automatically detected by your operating system. Use the onboard DIP switches or jumpers to select between RS232, RS485, and TTL modes before connecting your target device to the terminal blocks or pin headers.
