Description
The converter enables the connectionbetween two popular serialinterfaces USB and UART. The module is based on PL2303 circuit. The system is running on Windows 7 and Windows 8/8.1, without the need to install drivers.
The set also includes 4-pin cable with female ends
The module can be used to exchange data between the computer and the microcontroller system or for programming boards with remote serial interface, e.g.ArduinoorSTM32Discovery. The operating system is visible as a virtual COM port. It has a miniUSB connector, and 3 LEDs indicating the state of power supply, sending and receiving data.
The device works with voltages of 3.3 V and 5 V. The voltage VCCIO selection is performed using jumpers. Circuit board has connector raster of 2.54 mm suitable forbreadboardsor for connect using wires.
