Description

USB – RS232/TTL/UART converter – 3.3V/5V output

Module on CP2102 chip, works with 3.3 and 5V devices. The converter finds its application in places where a serial port is used for communication, viz: GPS,GSM, Arduino chips, routers, decoders, etc. The converter is also used to program some microcontrollers, such as the Arduino mini.

Technical data

• Layout: CP2102
• Connector: USB A
• Output signals on goldpin connector: TX, RX, DTR, CTS, GND, VCC
• LED indicating power to the circuit.
• TX data send indicator led
• RX data reception indicator led
• Output voltage on VCC pin: 5V
• Logical level of signals RX, TX, DTR – 3.3V / the circuit tolerates 5V, so that, you can directly connect for example with circuits such as ARDUINO /
• Supported on systems: Windows XP/Server 2003/Vista/7/8/8.1/10/WinCE/Macintosh OSX/Linux/Android

Procedure for using the converter with Arduino and similar circuits

If you want to use the converter to upload a program to an Arduino or similar circuit, you should reboot the entire external circuit immediately after compilation (and at the beginning of uploading) (reset button on the Arduino PCB). This is how the programming sequence is defined, with an unrestarted microcontroller the program may not be uploaded.
