Communication module

Overview

type-C interface, supports reversible insertion, USB to TTL/232/485

The USB to serial port uses CH340B, which has a 485 enable terminal control pin, and the crystal oscillator circuit can be removed.

TTL to 232 uses MAX3232.

TTL to 485 uses SP3481.

Export TTL interface.

Few peripheral circuits.

The on-board mounting holes can be connected with key chains, hand straps, etc. for easy portability and storage.

The module is ultra-small in size, delicate yet elegant.

It is recommended to use blue for making boards

Quad-axis, questions about I2C communication?
My understanding is this:But the result is this:I have learned I2C before, but I only learned about 1-to-1 communication. I don’t know much about 1-to-many communication. I hope you can give me some a
When a USB device is inserted in vxWorks, where is the software interrupt response point?
After the device is plugged in, an interrupt should be generated. I can't find where the interrupt point is. I'm anxious!
Problems with F149 driving L298N
I would like to ask you all, I use F149 to drive two 9V motors through L298N. The MCU IO port is directly connected to the motor driver module. It seems that all the connections are correct, but the o
