পণ্য সারসংক্ষেপ (Summary)

Bridging microcontrollers and industrial hardware, the MAX485 RS485 to TTL UART Serial Converter Module manages long-haul data. At 3.3V to 5V power, it pushes signals across 1.2km via differential pairs. Use it for Modbus RTU communication where standard UART fails over distance. Key Features 1.2km Transmission Range: 2.5 Mbps throughput across 1200 meters of wiring. Stabilizes communication across large industrial sites. Differential Signal Logic: Integrated MAX485 chipset cancels local electromagnetic interference. Data stays clean near high-voltage lines. 32-Node Bus Capacity: Single master node controls up to 32 slave devices. Reduces wiring complexity in multi-point sensor networks. 120-Ohm Onboard Resistor: Integrated terminal resistor prevents high-frequency signal reflection. Stops bit-errors during long-distance serial transfers. Compact 44x14mm PCB: 5.08mm terminal pitch for secure industrial wiring. Fits into tight enclosures during load shedding repairs. Frequently Asked Questions How to use MAX485 with Arduino? Connect VCC to 5V, GND to GND, and DI/RO to UART pins. You must toggle DE and RE pins to switch between transmit and receive modes. What is the range of RS485 communication? Communication reaches 1.2 kilometers using standard twisted-pair cabling. Signal speed decreases as cable length increases toward this physical limit.
