Khadas VIM 3 AI utvecklingskort som ursprungligen tillkännagavs med Amlogic S922X SoC och nu kommer att ersättas med Amlogic A311D. En SoC-förändring motiverad av den högpresterande NPU som ingår i Amlogic A311D SoC. Till övriga specifikationer läggs en MIPI-CSI-port till där vi kan ansluta 4x 8MP-kameror. På operativsystemsnivå har vi Android 9.0, Ubuntu XFCE 18.04 och LibreELEC (Linux 5.1 + Kodi GBM) tillgängliga i lanseringen. Det finns i två version: VIM3 Basic – 2GB LPDDR4/4X RAM, 16GB eMMC 5.1 flash och  VIM3 Pro – 4GB LPDDR4/4X RAM, 32GB eMMC 5.1 flash.

Here would like to do simple introduce about Khadas VIM3, A311D = S922X + MIPI-DSI + NPU, and all software on S922X could be used on A311D, its other unique features are as follows:

+ Faster CPU Performance

+ Neural Processing Unit for A.I.

+ Switchable PCIe and USB 3.0

+ USB-C Power Delivery

+ Dual Independent Displays

+ Dual Cameras

The Khadas Vim3 will ship in Basic (2GB LPDDR4 and 16GB eMMC 5.1) or Pro (4GB/32GB) models, both of which offer 16MB SPI flash.

The VIM3 SBC is the latest addition to our popular Khadas VIM series. It is equipped with the powerful Amlogic A311D SoC, based on the big-little CPU architecture: x4 Cortex A73 performance-cores clocked at 2.2Ghz, and x2 Cortex A53 efficiency-cores clocked at 1.8Ghz, are merged into a hexa-core configuration, and fabricated with a 12nm process to maximise performance, thermal and electrical efficiency.

VIM3 is designed with the same form-factor as our popular VIM2 and VIM1. It is the size of a credit card, and fits perfectly inside our DIY Case. Although diminutive, VIM3 is competitively-priced and fully-featured; everything you need is already built-in. The Pro-model comes with onboard 4GB LPDDR4/4X RAM, 32GB of EMMC storage and 2T2R 802.11ac Wi-Fi with Bluetooth 5.0.

In addition, VIM3 comes with unique features designed for our customers. Digital-signage developers will love the onboard programmable MCU, MIPI-CSI for dual cameras, real-time clock and wake-on-lan functionality. We've also included a 3-axis digital accelerometer to detect signage orientation. The M2X Extension Board also provides an NVMe SSD slot, power-over-ethernet, 100 Mbit ethernet, 4G module slot, nano-sim slot, and GPIO.

The new VIM3 SBC goes beyond what our original VIM models have to offer. It has an onboard 5.0 TOPS NPU for neural network applications, an M.2 slot for NVMe SSDs that can switch between PCIe and USB 2.0 via Khadas KBI commands, and a USB-C port with 5-20 volt USB power-delivery input. Connect with up to 2 independent displays via HDMI (4K) and MIPI-DSI (1080P), one of which may be touch-enabled using the built-in TP connector.

*16GB eMMC read performance is lower than the 32GB version (Samsung eMMC documentation).

* Wi-Fi Distance: 7 meters from the testing router.

* TF-Card: SanDisk 16GB, Class-10 A1, HC-I

* USB 2.0 / 3.0: Samsung T5 Portable SSD

* PCI-e: Samsung EVO 970

VIM3 is compared with the Edge-V Pro, Odroid-N2 (4GB) and Raspberry Pi 4 (4GB).
