Converter enables the connection between two popular serial interfaces USB and UART. The module is based on the reliable system FT232RL from the company FTDI (documentation), ensures stable operation and cooperation with the most popular operating systems.
The module has leads in the form of angular goldpin connectors with the signals RxD, TxD, RTS, CTS, and power lines: the PWR and GND. The voltage level on pin PWR is selectable via jumper:
- 5V - power from the USB port through a polymer fuse, to prevent damage to the port (maximum current 500mA)
- 3.3 V - power from the internal stabilizer of FTDI chip ( current max. 50 mA)
The leads of the converter module.
In addition, on the soldering field, the configurable BUS pins were provided (C3, C4, C5) and the rest of the transmission signals: RI, DTR, DSR, DCD. They can be used in the case of more complex data transmission.
