Description
The converter allows for the connection between two popular serial interfaces USB and UART. The module is based on aFT232RL, works with Windows 7 and Windows 8/8.1.
Module is attached to the goldpin strap:male 1x40,1x40 femaleand6-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 microUSB connector, and 3 LEDs indicating the powerstate, 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 with raster 2.54 mm suitable forbreaboarsor for connection using wires. Contacts VCCIO, GND, TXD, RXD, RTS# and CTS# are already solderedgoldpin connectors - 2.54 mm raster. The rest need to solder by yourself.
