TTL To RS485 Module MAX485/Max3485 Module MCU Development Accessories with Overvoltage Protection

Notice:

When the power supply voltage is 5V, please select the MAX485 module.

When the power supply voltage is 3.3V, please select the MAX3485 module.

This module is equipped with lightning protection and overvoltage protection function, and the protection ability is stronger.

Module Features:

1. The modules all use industrial grade MAX485ESA chips

2. With 485 signal overvoltage protection function

3. With signal and power LED indicators, you can see the sending and receiving status

4. With 120 ohm termination resistance gating function, it can be directly short-circuited during long-distance communication

5. This module leads the 485 signal ground. Because the common mode voltage that the MAX485 signal can withstand is -7 to +12V, when some buyers buy modules without overvoltage protection from other stores, the common mode voltage of the 485 signal is too high. High causes the 485 to burn out or heat up. This shop's module can solve this problem.

6. The module uses tantalum electrolytic capacitors to filter the power supply, and the quality of the power supply is even better.

7. The module pin pins can be directly inserted into the 2.54-pitch hole board, which is convenient for development

8. All modules in our shop have been strictly tested to ensure the quality

9. There is a wiring diagram on the back of the module for your convenience

10. All modules are packed in anti-static bags, which are safe and reliable.
