Know before you buy
The ATMega16U2 chip improves the board's communication capabilities, allowing for faster data transfer rates and increased memory compared to older versions.
Yes, the board features an optional supply voltage setting, allowing you to switch between 3.3V and 5V to accommodate a wider variety of sensors and modules.
The IIC (or I2C) interface uses only two wires—SDA and SCL—to communicate with the microcontroller. This frees up your digital I/O pins for other sensors or actuators.
Yes, the shield is designed for direct plug-and-play connectivity, making it easy to attach sensors, servos, and relays without needing a breadboard or complex wiring.
Yes, it is fully compatible with the Arduino IDE and uses the same programming logic as a standard UNO, making it a drop-in replacement for most projects.
The board provides 500mA at 5V and 50mA at 3.3V. If your project involves high-power components like multiple servos or motors, you should use an external power supply to avoid damaging the board.
