USB to TTL (Serial) Converter – CH340G

This is a CH340G USB to TTL (Serial) Converter. This converter is based on the CH340G USB to Serial TTL Converter chip. TTL stands for Transistor-Transistor Logic. This is a logic circuit technology used in digital circuits. TTL uses transistors to perform functions such as AND, OR, NOT, NAND, NOR, and XOR. The module can be used for 3,3V logic signals. You can switch to 5V using the Jumper Cap. The adapter uses the CH340 serial IC. This offers a low-cost alternative to FTDI-based modules. Although this adapter is cheaper, it does not lack any functionalities. After all drivers have been installed, the adapter will appear as a COM port on the computer. This makes it usable with programs such as the Arduino IDE.
