Bob is a 10-inch chromebook produced by Asus. It has two USB 3.0 type-C ports, 4GB of SDRAM, WiFi and a 1280x800 display. It uses its USB ports for both power and external display. It includes a Chrome OS EC (Cortex-M3) to provide access to the keyboard and battery functions. Support so far includes only: - UART - SDRAM - MMC, SD card - Cros EC (but not keyboard) Not included: - Keyboard - Display - Sound - USB - TPM Bob is quite similar to Kevin, the Samsung Chromebook Plus, but support for this is not provided in this series.
