Overview

The USB converter to Serial CP2102 is useful for communicating between a 3.3 V or 5 V micro controller and your computer.

Specification

• Integrated circuit CP2102;
• Logic levels: 3.3 V and 5 V;
• Baud rates supported:5 V output (maximum 500 mA);
  • 300, 600, 1200, 1800, 2400, 4000, 4200, 4200, 4200, 4200, 4200, 4200, 460800, 500000, 576000, 921600;
• 3.3 V output;
• Integrated LEDs indicating data reception / sending;

Instructions for use:

1. Install the CP210x driver.

Before using the product, you need to install the CP2102 driver on your computer. The driver can be downloaded from this  address.  Usually, the driver must be installed on Windows or Macintosh OSX. Most Linux versions have this driver included.

2. Make the hardware connections.

Before making the hardware connections, turn off the expansion card and disconnect the converter from the PC. Also disconnect all sensors attached to the development board.

The converter is capable of feeding the development board to be programmed. (max 500 mA). Connect the 3.3V pin to the expansion board power pin if it is running at 3.3V. Otherwise, connect the 5V pin to the power pin.

The remaining pins connect as follows:

• DTR / RST <-> reset board of the development board;
• GND <-> GND;
• RXD <-> TXD;
• TXD <-> RXD;

Example of connecting to a 3.3V Arduino Pro Mini compatible development board.

3.Charge the code on the development board.

After connecting the converter to the development board, you can enter it into your computer and select the port by opening the Tools -> Port menu . Press the "Upload" button or the CTRL + Ushortcut to load the code on the development board. After the code has been written to the memory, you will receive a confirmation message that there are no problems. Otherwise, the upload is stopped and details about the problems will be displayed.
