How Makers Can Go Pro with Android Things

This presentation was given at GDG DevFest Western Kenya 2017, Kisumu on the 25th November 2017. It covers Open Source Hardware and Android Things. It also covers the steps and tools you need to go from your developer kit prototype to fabricating custom boards for your own product. You can now build powerful connected devices that perform Computer Vision and Audio Processing using the Google’s IoT Platform.
