CH343G USB to serial port small board

Overview

1. Using the CH343G chip recently launched by WCH, the speed and stability are improved. It has built-in crystal oscillator and other components and only needs one capacitor to work. 2. 3.3V IO level, can pass about 10ma current. 3. Built-in unique ID to prevent the serial port number from changing after plugging into another USB port. 4. Provides 1.25mm cable interface and 2.54mm pin interface. 5. Can output 5V 500mA. Onboard resettable fuse and anti-backflow diode.

Note: The TXD and RXD marked on the board refer to the TXD and RXD of the target system (not those of the CH343G chip), and no cross connection is required.

Which book is good for learning single-chip microcomputer? 51 single-chip microcomputer tutorial book recommendation
I found a very good book on microcontrollers and would like to recommend it to beginners. It is suitable for self-study.
About NRF24L01
Has anyone used 51 to tune NRF24L01? I have a problem. When I use the code to check it, it is always not in place. However, when sending, the sending bit of the return value sta is indeed sent success
Can lm324 achieve a 0.05hz second-order high-pass filter?
I am designing an ECG collector for class. I want to use LM324 to make a 0.05Hz high-pass filter. I don't know if it is feasible. No matter how I change the resistors and capacitors, the cut-off frequ
