1 Introduction
- The Matrix - USB2UART is a USB to TTL serial module that uses high-quality CH340T bus interface chip to achieve bi-directional conversion between USB and TTL serial interfaces.
- The module has a 500mA self-recovery fuse, which effectively prevents short circuits and over-current damage to the USB port. It can output 5V voltage, which can be controlled by a switch and also includes reverse connection protection. Additionally, the Tx and Rx pins of the serial port have increased protection against high voltage.
2 Features
- Interface: 2.54mm 4-pin header
- Short-circuit protection
- Over-current protection
- Reverse connection protection
- High-voltage protection
- 5V output switchable
- PCB size (mm): 18x30
- Pin descriptions:
| Name | Description |
| GND | Ground |
| 5V | Power supply 5V output (up to 500mA) |
| RX | Serial port receive pin of module |
| TX | Serial port transmit pin of module |
3 Driver Installation
Note: No driver installation is required for Linux.
Insert the module into a USB port on your computer and check whether the serial port is recognized in the device manager. If it is not recognized, download and install the serial port driver from the following link: Matrix - USB2UART Driver
If the serial port is recognized correctly on your PC, it will appear as shown below. In this example, the local serial port is COM11:
