The NanoPi Duo2 ("Duo2") is a compact ARM-based development board designed by FriendlyELEC for makers, hobbyists, and IoT developers. Measuring just 55 x 25.4 mm, it is equipped with an Allwinner H3 quad-core Cortex-A7 processor, 256MB/512MB DDR3 RAM, an onboard WiFi and Bluetooth module, and an OV5640 camera interface. The board supports Linux variants such as Ubuntu Core and can be powered via its MicroUSB port, with booting available from a MicroSD card. Despite its small size, the NanoPi Duo2 provides a wide range of hardware resources for embedded projects. For connectivity and expansion, the NanoPi Duo2 offers support for USB, SPI, UART, I2C, PWM, IR, audio input/output, and Fast Ethernet, making it compatible with standard breadboards and external peripherals. It also supports open-source software utilities such as WiringNP and Python, enabling developers to easily prototype and implement applications. With its rich interfaces, compact form factor, and reliable performance, the NanoPi Duo2 is well-suited for IoT projects, prototyping, and educational use cases.
