Product Information

Product description

VIM4 Amlogic A311D2 SBC supports 4K UI & HDMI Input

The VIM4 SBC is the latest addition to our popular Khadas VIM series. It has a powerful Amlogic A311D2 SoC, featuring a 2.2GHz quad core ARM Cortex-A73, and 2.0GHz quad core Cortex-A53 CPU. HDR10, HDR10+, HLG and PRIME HDR video processing are supported, and TrustZone based security is used for DRM video streaming.

Developers and device manufacturers will love the programmable 32-bit STM32G031K6 MCU, wide 9-20V range of VIN power input, dual MIPI-CSI interfaces for two cameras, real-time clock, wake-on-lan functionality, and 3-axis g-sensor for orientation detection. The MIPI-DSI interface has touch panel functionality, so you can even build touch-sensitive interactive displays for your customers.

The new VIM4 SBC goes beyond what our original VIM models have to offer. It has an onboard micro HDMI input port for smart display & video conferencing applications. Four HDMI display outputs (HDMI, MIPI-DSI, V-by-One & eDP) means you can connect up to 3 displays simultaneously (including touch) without the need of costly adapters and custom boards.

HDMI Input/Output

The HDMI input on your VIM4 allows it to function as a home theater receiver. This input is designed to accept a micro HDMI cable, through which audio and video are digitally transferred from the HDMI outputs of other devices, such as a PC, game consoles and A/V receivers.

High Performance

CPU - 2.2GHz Quad core ARM Cortex-A73 and 2.0GHz Quad core Cortex-A53 CPU with 32-bit STM32G031K6 microprocessor.

GPU - Mali G52MP8(8EE) 800Mhz GPU, supports 4K UI, 8K 24fps decoder, H.264 and H.265 encoding at 4K 50fps, multi-video decoder up to 4Kx2K@60fps + 1x1080P@60fps.

RAM

Larger RAM

8GB LPDDR4X 2016MHz, 64bit RAM for memory intensive software applications.
