Customer Questions & Answers

What are the dimensions, weight and exact contents included in the package?

The module measures 44 mm long by 14 mm wide, with an approximate weight of 4 grams. The package includes exclusively 1 MAX485 module, with no cables or additional accessories.

Does it require any special maintenance or does the module have any notable operating limitations in industrial environments?

The module does not require periodic maintenance, but it should be protected from moisture and dust to prevent corrosion. It operates correctly between 0°C and 70°C; exceeding this range reduces service life and reliability. In industrial environments with high electromagnetic noise, shielding the cables is recommended to maximise stability.

What objective differences does it have compared with other TTL-RS485 conversion alternatives in terms of speed and distance?

The MAX485 supports transmission speeds of up to 2.5 Mbps and distances of up to 1.2 km with suitable wiring (twisted pair, 24 AWG), comparable to other standard RS-485 transceivers. Its low power consumption (less than 300 μA in standby) makes it efficient compared with older options such as the SN75176.

What is the MAX485 TTL RS485 adapter used for?

It is used to convert TTL signals to RS-485, allowing long-distance serial communication in Arduino and Raspberry Pi projects.

Is it compatible with Raspberry Pi?

Yes, this module is compatible with Raspberry Pi and Arduino, making RS-485 serial communication easier on both systems.

What voltage does the MAX485 module need?

The module operates with a 5V power supply.

What connections does the module have for easier use?

It has 2-pin screw terminals for AB connections and pins for a breadboard or DuPont wires.

Can I use it for DMX projects?

Yes, the module is useful for DMX applications and for extending the range of other serial connections.
