Asus Japan announced this week that it'll show off two new single-board computers at the upcoming ET & IoT Technology 2019 event kicking off November 20 in Yokohama, Japan. The latest Tinker Edge T and Tinker Edge R are designed specifically for IoT (Internet of Things) and edge AI applications. The Tinker Edge T measures 85 x 56mm, which is around the size of a credit card. Both single-board computers depend on a small heatsink with an accompanying cooling fan to stay cool during operation. The system also relies on the Vivante GC7000 Lite 3D graphics engine and Google's Coral Edge tensor processing unit (TPU), which is optimized for Tensorflow Lite and boasts performance up to 4 tera operations per second (TOPS). The Tinker Edge R employs a Rockchip RK3399 Pro system on chip (SoC) that boasts a three-in-one design.
