Product Introduction:
For 5V power supply, select the MAX485 module; for 3.3V power supply, select the MAX3485 module.
This module features built‑in lightning and overvoltage protection for enhanced durability and reliability.
Features
Industrial‑grade core – Equipped with genuine MAX485ESA chips for stable, long‑term operation.
Overvoltage protection – Safeguards the RS‑485 signal lines against voltage spikes.
Visual indicators – Onboard LEDs for power and data activity, making communication status easy to monitor.
Selectable termination resistor – A built‑in 120Ω resistor can be easily enabled via jumper for long‑distance communication.
RS‑485 ground reference – The module brings out the signal ground. Unlike unprotected modules that may overheat or fail due to excessive common‑mode voltage (beyond the MAX485’s rating of –7V to +12V), this design effectively prevents such issues.
High‑quality power filtering – Tantalum electrolytic capacitors ensure cleaner, more stable power delivery.
Breadboard‑friendly layout – Pin headers are spaced at 2.54mm (0.1"), compatible with standard perforated prototyping boards.
100% tested – Every unit undergoes rigorous testing to guarantee quality.
Easy installation – Wiring diagram printed on the back of the module for quick reference.
Safe packaging – All modules are shipped in anti‑static bags for added protection.
