SKU CH-Z675-P1E1B

Single-board computer with Amlogic A311D2 processor, 3.2 TOPS NPU, 8GB LPDDR4X memory, WiFi 6 and Bluetooth 5.1, active cooling, and four display interfaces

  • Amlogic A311D2 quad Cortex-A73 at 2.2 GHz and quad Cortex-A53 at 2.0 GHz for demanding workloads
  • Mali G52 MP8 GPU at 800 MHz handles 4K UI and H.264/H.265 encoding at 4K 50 fps
  • Three independent displays via HDMI, MIPI-DSI, V-by-One and eDP interfaces simultaneously
  • 8 GB 64-bit LPDDR4X at 2016 MHz with OOWOW embedded service for online OS delivery
  • AP6275S Wi-Fi 6 module with 2×2 MIMO, RSDB and Bluetooth 5.1 for fast wireless connectivity

Single-Board Computer with NPU

The Khadas VIM4 board pairs an Amlogic A311D2 processor with an integrated 3.2 Tops NPU and active cooling, aimed at developers and makers building edge-AI appliances, smart displays or video-conferencing endpoints. Its 8 GB of 64-bit LPDDR4X memory at 2016 MHz supports memory-intensive workloads.

HDMI Input and Triple Independent Displays

The defining spec is native HDMI input combined with four output interfaces — HDMI, MIPI-DSI, V-by-One and eDP — that can drive three independent 4K displays simultaneously. Buyers who need only a single screen or lack an HDMI capture requirement should look elsewhere.

Maker-Friendly Setup with Embedded OS Service

The board ships with an active cooling kit pre-fitted and uses the OOWOW embedded service for online OS delivery and device maintenance, reducing first-boot friction. Common pitfalls include overlooking the need for USB-C PD power under heavy load and ensuring the M.2 accessory connector matches the intended NVMe or 5G module.

Questions about this item

How does the 3.2 TOPS NPU perform in a real machine?

The 3.2 TOPS NPU handles AI inference tasks such as object detection and voice recognition directly on the board, reducing cloud latency for smart display and video conferencing applications.

What does the Wi-Fi 6 interface with 2x2 MIMO and RSDB cap in practice?

Wi-Fi 6 with 2x2 MIMO and RSDB delivers high-throughput, low-latency wireless connectivity, supporting simultaneous dual-band operation for stable streaming and networking.

What mounting holes or physical space does the VIM4 board need to fit?

The single board computer uses a standard form factor compatible with common SBC mounting holes and enclosures, and includes an active cooling kit that adds height for thermal management.
