From the project

Universal USB-UART converter ideal for prototyping high-quality devices. USB Full Speed/Full Handshake support.

The module provides the ability to power your devices via 5V from USB and 3.3V from the integrated power source simultaneously. The protection of the host device for overcurrent is realized by reversible fuse (750mA). 5V header is powerd from USB bus (trought fuse). The 3.3V power source is supplied from an LDO integrated in the FTDI converter. The 3.3V current limit is 50mA.
