Khadas VIM3 SBC Launched with Amlogic A311D Processor, 5 TOPS NPU

We’ve previously written about Khadas VIM3 Amlogic S922X development board and revealed the price tag for VIM3 Basic ($69.99) and VIM3 Pro ($99.99) with a launch date announced for June 24. As time has passed, this has become “fake news” except for the launch date, as Khadas VIM3 SBC has indeed launched but for $99.99 (Basic) and $139.99 (Pro).

What’s going on? Why the large price increase? That’s because Khadas team has decided to provide a more powerful platform to the community, and replace Amlogic S922X processor with Amlogic A311D processor boasting higher clock speeds and a 5.0 TOPS NPU. Another version may also become available later on with the soon-to-be-released Amlogic S922X-B processor whose Cortex-A73 cores are clocked at up to 2.2 GHz, instead of 1.7 GHz for the original Amlogic S922X processor that will be referred to Amlogic S922X-A in the future.

New Khadas VIM3 SBC specifications:

    • SoC – Amlogic A311D hexa-core processor with 4x Arm Cortex-A73 cores @ up to 2.2 GHz and 2x Cortex A53 cores @ up to 1.8 GHz, Arm Mali-G52 MP4 GPU, built-in Cortex-M4 core for “always-on” processing, and 5.0 TOPS NPU @ 800 Mhz with support for Tensorflow, Caffe and other deep-learning frameworks
    • MCU – STMicro STM8S003 with Programmable EEPROM for power management, customizations, and boot media configuration
    • System Memory & Storage
      • VIM3 Basic – 2GB LPDDR4/4X RAM, 16GB eMMC 5.1 flash
      • VIM3 Pro – 4GB LPDDR4/4X RAM, 32GB eMMC 5.1 flash

    • Video Output & Display Interface
      • HDMI2.1 transmitter with 3D, Dynamic HDR, CEC, and HDCP 2.2 support
      • 30-pin 0.5mm Pitch FPC Connector for 4-lane MIPI-DSI interface up to 1920 x 1080
      • 10-pin 0.5mm Pitch FPC connector for touch panel
    • Video
      • 4K UHD H.265 75fps 10-bit video decoder & low latency 1080p H.265 / H.264 60fps decoder
      • Supports multi-video decoding up to 4Kx2K@60fps + 1x1080P@60fps
      • Dolby Vision and HDR10, HDR10+, HLG, and PRIME HDR video processing
  • Audio – 8-ch I2S for microphone array applications over M2. connector
  • Camera – 30-pin 0.5mm Pitch FPC connector for 4-lane MIPI CSI with dual camera support; 8MP ISP
  • Connectivity
    • Gigabit Ethernet with WoL support
    • Dual-band 802.11a/b/g/n/ac WiFI 5, 2X2 MIMO with RSDB and Bluetooth 5.0 via Ampak AP6398S module
  • USB – 1x USB  3.0/2.0 type-A port, 1x USB 2.0 type-A port, 1x USB 2.0 OTG type-C port with USB PD support
  • Sensor – KXTJ3-1057 3-axis digital accelerometer
  • Expansion
    • M.2 Socket with single lane PCIe 2.0, USB 2.0, I2S, I2C, ADC, 100M Ethernet PHY interface, GPIO, MCU_PA2
    • 40-pins 2.54mm pitch header exposing:
      • CPU signals – USB, I2C, I2S, SPDIF, UART, PWM, ADC
      • MCU signals – SWIM, NRST, PA1
  • Misc – 2x IR receivers; RTC & battery header; 4-pin cooling fan header with PWM speed control; 3x user LEDs; power, func and reset buttons; XPWR pads for an external power button
  • Power Supply – 5V to 20V via USB-C port or pogo pads
  • Dimensions – 82.0 x 58.0 x 11.5 mm (4x M2 mounting holes)
  • Weight – 28.5 grams
  • Certifications – CE, RoHS

So basically nothing has changed from the specifications, except for the faster processor which also includes a 5 TOPS NPU, and a MIPI CSI camera interface. If you’d want to reproduce a similar configuration with ODROID-N2 or Raspberry Pi 4, you’d need to spend $60-$70 extra to get a neural compute stick, but obviously that only makes sense if your application can leverage AI acceleration.
