Khadas VIM4 Amlogic A311D2 8GB LPDDR4X 32GB development board

IoT Edge Development Board

The Khadas VIM4 is a single-board computer built around the Amlogic A311D2 processor with 8GB LPDDR4X memory and 32GB storage. It targets developers creating smart displays, video conferencing endpoints or multi-screen kiosks that need HDMI input and 4K output. The board also suits edge AI prototypes thanks to its 3.2 TOPS NPU.

Thermals and Power Envelope

The SoC combines four Cortex-A73 cores at 2.2GHz with four Cortex-A53 cores at 2.0GHz alongside a Mali G52MP8 GPU at 800MHz. A 32-bit STM32G031K6 MCU handles low-power management tasks. Power enters through a wide 9-20V VIN range, and the AP6275S Wi-Fi 6 module supports 802.11a/b/g/n/ac/ax with 2x2 MIMO and RSDB alongside Bluetooth 5.1.

Build and Connectivity Implications

Four display interfaces — HDMI, MIPI-DSI, V-by-One and eDP — enable up to three independent screens simultaneously, with touch support on the MIPI-DSI link. A micro HDMI input port receives 4K 60fps signals from PCs, consoles or AV gear. Dual MIPI-CSI connectors accept two cameras, while an onboard 3-axis g-sensor and real-time clock aid orientation-aware and wake-on-LAN applications. OOWOW embedded service streamlines OS delivery and device maintenance. Builders needing more than 32GB of onboard storage or a second NPU should look elsewhere.
