## Description

## Overview

The Khadas Edge 2 is one of the thinnest single-board computers ever produced — just 5.7mm bare or 11mm with its bundled heatsink and fan. Built around the Rockchip RK3588S2 (an enhanced RK3588S revision), it delivers the full octa-core 2.25GHz ARM performance and 6 TOPS NPU capability of the RK3588 family in a form factor closer to a credit card than a traditional SBC.

The design sacrifices built-in Ethernet and a traditional 40-pin GPIO header to achieve its extreme thinness. Networking requires either a USB dock or the Edge2 IO expansion board. Instead, Khadas focuses on wireless: an integrated AP6275P module provides WiFi 6 (802.11ax, 2×2 MIMO) and Bluetooth 5.0. All expansion is handled through two 30-pin FPC connectors exposing CPU signals (I2C, UART, SPI, I2S, SDMMC, ADC, PWM, USB) and MCU signals, plus 7 pogo pads.

Display support is a highlight: the USB-C port supports DisplayPort Alt Mode alongside USB 3.1 data and USB Power Delivery, enabling four independent simultaneous display outputs. Two MIPI DSI connectors and three MIPI CSI interfaces are exposed via FPC for embedded display and camera integration.

Available in Basic (8GB/32GB) and Pro (16GB/64GB) configurations, the Edge 2 ships as either a standalone SBC (Maker Kit) or as an ARM mini PC with aluminum enclosure. Armbian, Ubuntu, Debian, and Android are supported. It excels as a compact AI inference node, embedded vision platform, and tightly integrated embedded computing module.
