CP2102 USB To TTL Converter Module is a small and easy USB to TTL converter for STC microcontroller download DVD/ hard disk/router/GPS upgrade, which is based on CP2102 USB-to-UART bridge controller chip. This compact MLP-28 package chip consists of a USB controller, USB transceiver (no external resistors required), oscillator (no external crystal required), 1024-Byte EEPROM (to keep data such as vendor ID, product ID, serial number, power descriptor, release number, and product description strings), and asynchronous serial data bus (UART) with full modem control signals.
This module has a 500mA auto-recovery fuse path, preventing to burn of computer USB due to power failures. It can directly plug into the PC USB port and be supplied by this port and no need external power supply. It has an LED indicator to show power and transceiver stats. Also, this LED indicator shows the transceiver speed by speed flashing, so the higher the intensity means the lower the baud rate.
