MAX485 module, a converter that enables communication between devices using the RS-485 serial communication protocol. The RS-485 protocol is commonly used in industrial environments and other applications that require long-distance and reliable data transmission.

This specific module allows you to convert TTL (Transistor-Transistor Logic) signals, which are commonly used in lower-power digital circuits, to RS-485 signals suitable for longer distances and harsher electrical environments.

Specification 

• MAX485 chip: This is the core component that performs the TTL to RS-485 signal conversion.
• Input/Output (I/O) connections: The module has various connection points for power, TTL signals (TXD, RXD), and RS-485 signals (A, B). (TXD and RXD refer to Transmit Data and Receive Data).
• Enable pins (DE, RE): These pins provide control over the RS-485 transceiver chip, enabling or disabling transmission or receive functions
• Compact size: The module’s small footprint makes it suitable for integration into space-constrained applications.
• Efficient Operation: Low power consumption with an advanced chipset for energy-saving yet powerful operation.
