1. Introduction

1.1 Purpose and Description

Dusun Pi4 is an IoT gateway for developers, similar to Raspberry Pi4. It adopts a Rockchip RK3568 processor, based on ARM Quad-core Cortex-A55 core, 64bit, 2GHz.It can run multiple systems, Linux, Debian, Android, etc., with a rich external interface, HDMI, USB, and Ethernet. And compared to raspberry pi 4, it has a built-in IoT wireless module, including Zigbee,z- wave, Bluetooth, Wi-Fi, and LTE. Developers can quickly develop their gateways. and hardware encryption and is also supported.
