Matrix - USB2UART
From FriendlyELEC WiKi
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.
