2AT7Z-GHUB0203Gravio Hub 2

Geavio Hub2 User's Manual GHUB002 2022/06 Product overview Gravio hub 2 is a linux-based smart IoT system. We build it by arm chip rockchip3399,and in IoT it has built-in zigbee3.0 chip, which can be compatible with the zigbee sensor on the market to form a smart home. It can exchange and send commands in parallel with the wireless sensor in hex code based on the serial protocol. At the same time, WiFi and Bluetooth have also created conditions for communication with other devices. 2 Front view The Gravio hub 2 is designed to be very compact, with a full-featured USB typc-c interface and a button. This interface supports the pd power protocol, dp video protocol, and usb3.1.and also it is have usb-a 2.0、rj-45、hdmi port。 At the same time, the Gravio Hub 2 also supports the use of linked displayer. You can directly plug in the dual-headed full protocol USB type-c cable on the display that supports the USB type-c full protocol interface to light up the screen, or you can use the extension. The dock lights up the display and enters the UBUNTU system that comes with the body Gravio Hub 2 also supports hmdi video output reality, up to 4k resolution video output, at the same time, usb 2.0 supports the use of input devices such as mouse and keyboard and U disk and other devices, we also prepared a wired network interface for you to use better it. Wireless Instructions for use First open the serial debugging assistant, such as sscom, set the baud rate to 115200, open the serial port after 8N1.
