I2C MODULE

I2C Interface Module

Compact I²C Module for easy sensor and peripheral connection via the I²C (TWI) bus. Ideal for rapid prototyping, embedded systems, and mass-production electronics where multiple devices share the same two-wire bus.

Key Features

• Standard I²C (TWI) interface — SDA & SCL pins for daisy-chaining multiple devices
• Supports speeds up to 400 kHz (Fast mode) — compatible with 100 kHz and 10 kHz modes
• On-board pull-up resistors (configurable) for plug-and-play operation
• Wide voltage range: 3.3V / 5V compatible for logic-level flexibility
• Compact PCB with clearly labeled pads/pins for quick wiring or header soldering
• Low-power consumption — suitable for battery-powered applications

Technical Specifications

Applications

• Connecting sensors (temperature, humidity, accelerometers, magnetometers)
• Expanding GPIO using I²C port expanders
• Real-time clock (RTC) modules and EEPROM communication
• Robotics, wearables, and IoT sensor networks
• Prototyping and production where multiple peripherals share one bus

Package Includes

• 1 × I²C Interface Module
• 1 × 4-pin header (optional, depending on listing)

Why Choose This I²C Module?

• Plug-and-play with common microcontrollers: Arduino, ESP32, Raspberry Pi, STM32, and more
• Flexible voltage compatibility (3.3V/5V) — no level-shifter needed in most setups
• Compact, robust design for both hobbyist projects and industrial deployments

Note: If you plan to use many devices on the same I²C bus, ensure unique addresses or use an I²C multiplexer/port expander.
