RS485 Light Sensor Interface Board
This Arduino-compatible hardware is primarily designed for RS485-based applications. It features an ATmega328 microcontroller, RS485 SN65HVD485E Half-Duplex RS-485 Transceiver chip, OPT101 light sensor, multiple I/O lines, and a provision for mounting a 0.96-inch OLED display.
A simple and practical example application is a light sensor system communicating over RS485. Screw terminals are provided for easy connection of the RS485 A and B twisted pair cables, while all other I/O lines are accessible through header connectors.
This board is ideal for developing light-sensing and other sensor-based RS485 communication projects.
