The Seeeduino Cloud combines an ATmega32u4 microcontroller with an embedded Linux system (OpenWrt) powered by the Atheros AR9331 processor. Compatible with the Arduino Yun, this board provides built-in Wi-Fi and Ethernet connectivity, making it ideal for IoT projects that need network access without external shields.

The dual-processor architecture lets you run Arduino sketches on the ATmega32u4 while offloading network operations, HTTP transactions, and web service processing to the Linux side via the Yun Bridge library. The board can be programmed over USB or wirelessly through Wi-Fi — no physical access needed.
