Khadas VIM4
A compact Amlogic SBC with OOWOW recovery, MIPI interfaces, 40-pin GPIO, and an NPU for media and edge AI prototypes.
Processor
Amlogic A311D2
Logic
3.3 V GPIO
Power
USB-C Power Delivery
Format
Compact media/AI SBC
Check before wiring
- Use Khadas pinout tables; 40-pin layout is not guaranteed Pi-compatible.
- Power delivery requirements can change with peripherals attached.
- Some pins are muxed with onboard devices and high-speed connectors.

Simplified technical illustration. Pin data is source-backed; verify against the linked documentation before wiring.
Hover, tap, or focus a pad to inspect a pin. Use arrow keys to move between pins.
- Official Khadas VIM4 40-pin header table; numbering is not Raspberry Pi odd/even style.
- Khadas notes vendor-kernel GPIO numbers differ from mainline Linux.
- Several pins are power, ADC, MCU, USB hub, or power-enable signals rather than generic GPIO.
