5) Size:200*135mm ->7.87inch * 5.31inch.

- Technical Details Introduction

RAB Holder, also called Raspberry Pi, For Arduino and Breadboard Holder. Presumably you can know its function from the name. It can ensure the security of your demoboard and avoid placing the demoboard on the desk freely to cause short cut. The RAB Holder also simplifies your experiment when you are building a complex circuit. There are three zones on the RAB Holder and each has a name on it. We have made some slots in the zone that used to fix the Raspberry Pi to make the use more comfortable.

A screwdriver is provided for you to install the Raspberry Pi and for Arduino board onto the holder with screws.

Resolution:1024x600

Visible area: 150mm x 85mm

Weight:300

* Contents

- Yes, this is an adorable small HDMI television with incredibly high resolution! We tried to get the smallest possible HDMI display with high-res, high-contrast visibility. The display is very easy to use

- it should be powered by 12DC, then connect a digital video source to one of the ports. It work connect to any device with direct HDMI such as raspberry pi, banana pi and pcduino. The biggest difference is that it can work when you plug it on device without any software support.

- If you want a power adapter : 12V/2A Power Supply
