Communications & Interfacing

About

Communications and interfacing modules enable reliable data exchange between microcontrollers, sensors, displays, and external systems. From logic level translation to industrial serial protocols, our range covers the essential interface components for embedded systems, IoT devices, and industrial automation applications. Our Communications & Interfacing collection includes: Logic Level Converters — 8-channel high-speed bidirectional level shifters for bridging 3.3V and 5V devices; essential for I2C, SPI, and UART interfacing between Arduino, Raspberry Pi, and modern 3.3V sensors I2C Interface Adapters — PCF8574-based LCD I2C backpack modules that reduce 16-pin LCD wiring to just 4 wires, supporting all standard HD44780-compatible displays RS-485 Interface Modules — MAX485 TTL-to-RS485 converter modules for long-distance, noise-immune serial communication in industrial environments; supports half-duplex multi-drop networks up to 1200m All modules are breadboard and PCB compatible with standard 2.54mm pin spacing. Suitable for Arduino, Raspberry Pi, ESP32, STM32, and industrial PLC interfacing applications.
