                                                CP2109-A01-GMR Overview
There is a copy of it in the 28-VFQFN Exposed Pad package. This packaging has a Tape & Reel (TR)-shape, making it convenient to carry around. Keeping the temperature at -40°C~85°C will ensure reliable operation. With a 3.3V~3.6VV power source, you should be able to use it. In it, there are 28 terminations. 3.3V is an ideal supply voltage for high efficiency. CP2109-A01 numbers are members of the family. Currently, the gadget is receiving current from a 17mA-shaped supply. It is set to 3.3V in the power supply settings for the component. Bus Controllers is a self-contained device.
