What Types of Wireless Modules Can You Usually Divide Into?
What types of wireless modules can you usually divide into?
The important use of wireless modules such as a/b/g/n/ac BT Module is to use the microcontroller to achieve data communication, then what types of wireless modules can usually be divided into? The following is a detailed understanding.
1.ASK superheterodyne module: we can use it as a simple remote control and data transmission;
2. Wireless transceiver module: mainly uses a single-chip microcomputer to control the wireless module to send and receive data, commonly used modulation modes are FSK, GFSK;
3. The wireless data transmission module mainly uses the serial port tool to receive and send data, and the customer is easy to use. The wireless modules on the market are widely used, and the frequencies are 230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, and the like.
