Developed by FTDI (Future Technology Devices International), the FT232 is a widely recognized USB-to-serial converter chip. It has been a popular choice for many years due to its robustness, reliability, and extensive driver support across different operating systems. The FT232 offers advanced features such as Bit Blast Mode, which allows each pin to be controlled individually, making it suitable for a wide range of applications beyond standard serial communications. It operates at 5V or 3.3V logic levels and supports a variety of baud rates.

What is CH340?

The CH340 is a USB to serial converter chip produced by Chinese manufacturer WCH. Widely used due to its low cost and availability, the CH340 is capable of converting USB signals to UART (Universal Asynchronous Receiver-Transmitter) signals, making it suitable for connecting microcontrollers, Arduino boards, and other devices to a computer. It supports a range of baud rates and operates at 5V or 3.3V logic levels. However, it may require specific drivers to be installed, as some operating systems do not support it on their own.

What is the CP2102?

Developed by Silicon Labs, the CP2102 is another popular USB to serial converter chip. It offers similar functionality to the CH340 with some significant differences. The CP2102 is known for its ease of use as it has a built-in driver, so additional drivers are usually not required on most operating systems. It supports multiple baud rates and operates at 5V or 3.3V logic levels. The CP2102 is favored for its reliability and compatibility across different platforms.

What is CH341?
