Features: 1. Onboard original FT232RL and SP485EEN chips; fast communication speed, stable and reliable, better compatibility 2. On-board integrated power isolation, providing stable isolation voltage, no additional power supply is required at the isolation end 3. Onboard integrated digital isolation, signal isolation, high reliability, strong anti-interference, low power consumption 4. Onboard TVS (Transient Voltage Suppressor), effectively suppressing surge voltage and transient peak voltage in the circuit, lightning protection and anti-static 5. On-board self-recovery fuse and protection diode to ensure stable current/voltage output, provide over-current/over-voltage protection, and improve impact resistance 6. Onboard 15KV ESD isolation protection and 600W lightning surge protection 7. The RS485/RS422 interface has a 120R terminal resistor on board, which is enabled by default and can be configured by jumpers 8. 3 LEDs to indicate power and transceiver status 9. Industrial-grade rail-type ABS shell design, small size, easy installation, high cost performance Product parameters: 1. Baud rate: FT232RNL (300bps-3Mbps) 2. Host port: USB 3. Device port: RS485/422 4. Working voltage: 5V 5. Connector: USB-B 6. Protection: 200mA resettable fuse, ESD protection 7. Transmission distance: about 5m 8. Connector: screw terminal 9. Pins: A+, B-, PE 10. Direction control: hardware automatic control 11. Protection: 600W lightning protection surge suppression, 15KV ESD protection (120R balance resistor on board) 12. Transmission distance: about 1.2km (low speed) 13. Transmission method: point-to-multipoint (MAX32 nodes, repeaters are recommended for more than 16 nodes) 14. LED indicator light: PWR: red power indicator light, it is on when there is a USB connection and voltage is detected; TXD: green TX indicator light, it is on when the USB port sends data; RXD: blue RX indicator light, when the device port sends data back lights up 15. Working environment temperature: minus 15-70 degrees Celsius 16. Humidity: 5%-95% RH 17. Operating system: Mac, Linux, Android, WinCE, Windows 10 / 8.1 / 8 / 7 / XP 18.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
