Khadas VIM4 development board 8GB LPDDR4X active cooling

SKU CH-EVKA-C8GW6

Single-board computer with Amlogic A311D2 SoC, 8GB LPDDR4X, 3.2 TOPS NPU, HDMI input, WiFi 6 and active cooling

  • HDMI input up to 4Kp60 for smart display applications
  • 2 TOPS NPU enables on-device AI inference
  • Mali G52MP8 GPU handles 4K 50fps H.265 encoding
  • 8GB LPDDR4X 2016MHz 64-bit for memory-heavy workloads
  • WiFi 6 2x2 MIMO plus Gigabit Ethernet for connectivity

AI development board with 3.2 TOPS NPU

The Khadas VIM4 is a single-board computer built around the Amlogic A311D2 SoC. It combines four Cortex-A73 cores at 2.2 GHz and four Cortex-A53 cores at 2.0 GHz with a Mali-G52 MP8 GPU at 800 MHz. An integrated NPU delivers 3.2 TOPS for on-device inference. Active cooling is included.

Makers and engineers needing HDMI input

This board suits developers building smart displays, video conferencing hardware or edge AI prototypes that require HDMI input up to 4Kp60. It also fits projects needing three independent screens via HDMI, MIPI-DSI, V-by-One or eDP. Buyers who need onboard storage or a bundled power supply should look elsewhere.

8 GB 64-bit LPDDR4X at 2016 MHz

The memory subsystem provides 8 GB of 64-bit LPDDR4X running at 2016 MHz, which determines how large a model or dataset fits in RAM. An M.2 slot accepts SSD or LTE modules for expansion. Gigabit Ethernet with WoL and AP6275S Wi-Fi 6 with 2x2 MIMO RSDB handle wired and wireless links.

Questions about this item

Does the active cooling kit keep the Amlogic A311D2 SoC quiet during continuous 4K 50fps encoding?

The included active cooling kit is designed to manage heat from the A311D2 SoC during sustained workloads such as 4K 50fps H.265 encoding, helping maintain stable performance.

Which power adapter and cable must I supply to run the board?

A USB-C power adapter and matching USB-C cable are required but not included; choose a supply that meets the board's power requirements.

Can I connect my existing HDMI monitor and MIPI-DSI panel to the three independent display outputs at the same time?

Yes, the board offers HDMI, MIPI-DSI, V-by-One and eDP interfaces and can drive three independent displays simultaneously.
