Khadas VIM3 Basic 4GB 32GB development board

Capability & Audience

The Khadas VIM3 Basic is a single-board computer built around the Amlogic A311D system-on-chip. It combines four Cortex-A73 cores at 2.2 GHz with two Cortex-A53 cores at 1.8 GHz on a 12 nm process. An integrated NPU delivers 5.0 TOPS INT8 inference for edge AI workloads. The board ships with 4 GB of LPDDR4 memory and 32 GB of onboard storage.

Pre-Purchase Checks

Confirm your power supply can provide USB-C Power Delivery to the board, as no adapter or cable is included. Verify that your target operating system — Android, Ubuntu or LibreELEC — supports the A311D SoC and the NPU toolkit you intend to use. Ensure any M.2 extension modules you plan to attach, such as an NVMe 2280 SSD or a 4G LTE module, match the single PCIe lane and the M2X interface specification.

Build & Daily Use

The board uses a thin, stackable form factor with four M2 mounting points for secure integration. A programmable MCU and three status LEDs give immediate visual feedback during development. Dual independent display output is available through HDMI for 4K resolution and MIPI-DSI for 1080p panels. The 40-pin GPIO header exposes USB, I2C, I2S, UART and ADC lines, while an M.2 connector adds eight-channel I2S for microphone arrays.
