Capacitive TouchScreen running on Jetson TX2

Today I received the 5 inch 800×480 Capacitive TouchScreen I ordered from Amazon. I decided to mount a touchscreen on the Valify Robot so that in a later stage I could add some nice feature for it (fast settings and a GUI controlling different things on the robot). But It will also be good to have in the developer stage of the robot, I could easily see whats going when doing different configurations.

Running the Capacitive TouchScreen on the Nvidia Jetson TX2 was very easy. Simply connect a HDMI to the Capacitive TouchScreen and the Jetson TX2 and then Plug in a USB cable between the Capacitive TouchScreen and the Jetson TX2 and you are good to go.

Here is the specifications on the Capacitive TouchScreen

Dimensions 184mm x 106mm x 45mm
Weight G.W 180g
Battery Exclude
Power 5V Power via USB Micro
Current Max 400mA
Display Type 5 inch TFT LCD

Touchscreen USB capacitive
Touch points 10 points maximum
Interface HDMI & USB 2.0 Full Speed

The Price for the Capacitive TouchScreen is around 60USD. The touch points on the screen is very accurate and precise, making it easy to hit even the smallest objects. For this price point I think the screen is very good, anyways I am happy.

Here is some pictures of the Capacitive TouchScreen:

The touchscreen will be mounted on the back on the robot and also be equipped extra ports in the back, making it easy to connect different things. The ports will be 1xHDMI, 2xUSB 3.0 and 1XUSB 2.0.

The HDMI port will be used to connect an external display in parallel to built in touchscreen, the USB 3.0 ports will be used for keyboard and mouse and the the USB 2.O will be used as a flash port for the Jetson TX2.

The Ports are ordered from CLIFF Electronic Components.

 

And finally here is some pictures with the screen mounted on the Valify robot. Did not have any 90-Degree HDMI connectors so that why the screen is lifted when powered on. 🙂 and please not that this is the first prototype of the mounting bracket for the screen. I have already spotted some improvements 🙂

  1. Hi,
    Which linux kernel you are using? According to Nvidia, they don’t support touch input on L4T distributions but as you mention above you didn’t have any problems in getting the touch input to work on your jetson tx2. I would really appreciate if you can shed some light on this.
