The computer has a respectable 1.8GHz ARM Cortex-A17 quad-core processor. It’s only 32-bit (unlike the Raspberry Pi 3) but it has a higher clock speed. The Tinker Board also sports an integrated ARM-based Mali-T760 graphics processor (GPU).
Before we explore the apps, there is a leitmotif. The multimedia experience on Android is not perfect with Bluetooth. I love my Bluetooth devices. But Bluetooth support on the Android image is a mixed bag. Audio with the Amazon Echo Dot is terrible. Fortunately, connecting via Bluetooth to a Cambridge MINX GO is much better. And pairing with an inexpensive pair of Bluetooth headphones was pretty reasonable, although audio syncing wasn’t perfect. For now, I’m connecting via its headphone socket.
