Seeeduino V4.3 (ATMega328P)

The Seeeduino V4.3 is not your typical Arduino-compatible board—it's the bread and butter for anyone serious about tinkering, without the hassle of jumpers or soldering. Powered by the reliable ATmega328P microcontroller and based on the classic Arduino UNO bootloader, this board is a stable, user-friendly, and versatile platform for your DIY electronics projects.

With 14 Digital I/O Pins (including 6 PWM outputs) and 6 Analog Inputs, Seeeduino V4.3 offers the flexibility you need for a wide range of applications. Whether you're building a robot or an IoT device, this board's compatibility with Arduino UNO-R3 shields means you have plenty of expansion options.

Switching between 3.3V and 5V operation is as easy as flipping a switch—literally. This feature is a lifesaver when you need to optimize power consumption without losing performance. Plus, with 3 on-board Grove connectors, the Seeeduino V4.3 allows for easy integration with a vast ecosystem of Grove modules, simplifying your prototyping process.
