ALLNET Rock Pi S - 512 MB with BT and WiFi PoE ready HAT possible (D4WP_512MB_WIFI/BT/LAN/PoE)

The ALLNET Rock Pi S is a compact and versatile single-board computer designed for IoT, edge computing, and embedded applications. Powered by the Rockchip RK3308 quad-core ARM Cortex-A35 processor and equipped with 512MB DDR3 RAM, it offers efficient performance for a wide range of projects. Built-in Wi-Fi 802.11 b/g/n and Bluetooth 4.0 provide wireless connectivity, while the 10/100Mbps Ethernet port and PoE support (via optional HAT) ensure flexible networking options. The board features a 26-pin GPIO header with I2C, SPI, UART, PWM, and I2S interfaces, making it ideal for prototyping and integration with sensors, actuators, and audio devices. With its small form factor (43.2 x 38.1 mm) and USB-C power input, the Rock Pi S is perfect for space-constrained applications.

Advantages

The Rock Pi S offers a cost-effective solution for developers and hobbyists seeking a low-power, feature-rich SBC. Its PoE readiness simplifies deployment in networked environments, while the comprehensive GPIO and interface support enables seamless integration with various peripherals. The board's compatibility with multiple operating systems (Debian, Ubuntu, Buildroot, Armbian, OpenWrt) provides flexibility for different use cases.
