FT232RL and CH340 are commonly used serial communication chips, their differences mainly lie in:
< br >
The FT232RL is a USB port, while the CH340 is a serial port.
< br >
Different performance: The FT232RL provides stable and reliable performance, while the CH340 provides more stable performance and supports higher baud rates and data transfer rates.
< br >
Different application fields: FT232RL is mostly used in USB-to-serial development boards and peripherals, while CH340 is mostly used in embedded systems.
< br >
Therefore, when choosing FT232RL or CH340, you need to choose the right chip according to the specific application scenario and requirements.
340 is very old, it is domestic, 232 is much more stable
