Description
The converter enables the connectionbetween two popular serialinterfaces USB and UART. The module is based on aFT232RL,works with Windows 7 and WIndows 8/8.1.
Module includes the6-pin cable with female ferrules and the necessary contacts.
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 power state, sending and receiving data.
The device works with voltages of 3.3 V and 5 V. The voltage selection is done using jumpers. Circuit board has connectors raster 2.54 mm suitable forbreadboardsor for connection using wires. Contacts VCCIO, GND, TXD, RXD, RTS# and CTS# are already solderedgoldpin connectors - 2.54 mm raster. The rest are sold separately and need to be soldered independently.
