High-Efficiency I2C Port Expansion for Microcontrollers

Are you running out of I2C ports on your microcontroller? Most Arduino boards only provide a single I2C interface, making it difficult and messy to connect multiple sensors, displays, or modules simultaneously.

The Keyes I2C Shield V1 solves this problem instantly. This dedicated expansion board turns your single I2C port into 10 accessible interfaces (utilizing standard 2.54mm 4-pin headers). It allows your microcontroller to communicate with up to 9 different sensor modules at the same time without complex wiring.

Key Features:

• Plug-and-Play: Dedicated 4-pin headers (VCC, GND, SDA, SCL) make connecting I2C devices simple.
• Clean Wiring: Eliminates breadboard clutter when using multiple I2C devices like LCDs, OLEDs, and sensors.
• Broad Compatibility: Ideal for Arduino Uno, Mega, and other MCUs requiring I2C expansion.

Specifications:

• Working Voltage: DC 5V
• Communication Protocol: I2C / IIC
• Pin Pitch: 2.54mm (Standard)
• Dimensions: 50 x 40 x 12 mm
• Weight: 9.2g
