Working Principle of PL2303 USB to TTL Converter

The PL2303 module works by translating USB data from a computer into TTL-level serial signals. When connected via USB, the computer recognizes the module as a virtual COM port.

Data sent from the computer is converted into serial TX signals, while data from the connected microcontroller is received via RX and sent back to the computer. This two-way communication allows for firmware uploads, serial monitoring, and real-time debugging.

Because the conversion is handled by the PL2303 chipset, no additional processing is required from the host system.
