GPIO Map
Overview
The Khadas VIM4 is built around Amlogic's A311D2 SoC — an octa-core processor pairing four Cortex-A73 cores at 2.2GHz with four Cortex-A53 cores at 2.0GHz, backed by a Mali-G52 MP8 GPU and a built-in 3.2 TOPS NPU for on-device AI inference. Khadas ships it in a fixed 8GB LPDDR4X / 32GB eMMC configuration, keeping the BOM predictable.
The board distinguishes itself from competing RK3588 designs with its Amlogic-based media processing heritage: hardware-accelerated video decode up to 4K, native HDMI 2.1 output for 4K@60Hz playback, and an HDMI input for video capture — a rare feature on compact SBCs at this price point. Both are active simultaneously.
Wireless connectivity is robust: the AP6275S module provides WiFi 6 (802.11ax 2×2 MIMO) and Bluetooth 5.1 without any external antenna socket needed, using an onboard PCB antenna. A standard Gigabit Ethernet port rounds out wired networking.
The 40-pin GPIO header exposes I2C, SPI, UART, I2S, and general GPIO lines, and the M.2 slot (PCIe 2.0) accepts NVMe SSDs. Armbian, Ubuntu, Debian, Android, and the Khadas vendor OS are all available with active image support, making the VIM4 a solid choice for media center builds, smart home hubs, voice assistant platforms, and edge AI prototyping.
Use Cases
