July 2021 - Update

Hello Community!

The month of July features various new software releases for Khadas SBCs. They were produced based on feedback from our community, and we hope that you’ll find them useful.

For distributors and retail customers, please note:

This is a pre-compiled demo app for your VIM3/3L's NPU (neural processing unit), and it will help you to quickly understand the basic capabilities of your Khadas SBC. Please note that this app was developed based on the 6.4.4.3 NPU SDK, so the Android OS of your VIM3/3L needs to be updated to the latest version before you can run the app.

A preview ROM for Android R (version 11) has been released for the Khadas VIM3. You may use the MD5 checksum to verify the integrity of the files that you’ve downloaded. To install the ROM into your VIM3’s eMMC, you’ll need some flashing tools.

Please note that Android 11 is still a work-in-progress, and we’ll commit the upstream patches to the Google Android AOSP together with the Baylibre Team. For developers who want to try out Android 12, you can download the latest Android source code from the Google AOSP website and build it yourself!

Tone2 Pro’s Updated Retail Price:

It is with a heavy heart that we have to announce an increase in the Tone2 Pro’s retail price, due to the global silicon chip shortage. The price will be raised from US$199.9 to US$249.9.

The increase in price for both distributors and retailers will begin from the launch of our as-of-yet unannounced new product, which shall remain a mystery for now.
