Easy Integration Guide
1. Connect VCC to your MCU’s 3.3 V or 5 V rail.
2. Wire GND to the common ground.
3. Link DI to the MCU’s TX pin and RO to the RX pin.
4. Control RE and DE together (logic HIGH = transmit mode, LOW = receive mode).
5. Attach the differential pair A and B to your RS‑485 bus.
With the EGBO MAX485 module, your serial network is up and running in minutes.
