For this example the CP210x module will be used to power the Teensy 2.0 at 5V after programming.
Both outputs are only rated of low currents (less than 100mA) but it can be very useful for powering a small system from a USB port.
Unique to this PCB implementation of the CP2102 is both a 5V and 3.3V output. This example will detail the wiring for a Teensy 2.0 microcontroller. CP2102 with other USB-UART adapter circuit works similar to the PC through the driver's USB port into a virtual COM port in order to achieve the purpose of expansion.
