5 Inch Resistive Touch Screen

This little screen is fantastic, and a pretty dang good deal, to boot! I wanted to make myself a little portable Pi-based machine to take with me on the go, and a 5-inch screen seemed just about the right size. There are plenty of choices here on Amazon, but I decided to give this one a shot since it could also be used as a regular HDMI monitor.As the instructions note, this will not work with your Pi right out of the box; it needs some drivers and configuration settings tweaked first, or it'll light up and look like it's broken at first. A helpful note card included with the display lists a couple websites - one is the company's wiki that lists step-by-step instructions on setting things up, and the second is a helpful youtube video that gives a full run-down as well. Following the instructions on the wiki was a snap - Just install the latest Raspbian, copy/paste some configuration settings, clone Elecrow's git repository, run the binary, and reboot. Voila, a bright, sharp, vibrant display, ready to go.I'm currently attempting to find a nice case to put it all in for safer transport, but even without that, I'd say this is a great choice if you just want a small touchscreen display for your Raspberry Pi.

This screen is a great little device. It is bright and crisp. The touchscreen works well. Installing it took me quite a few tries though, so I thought I would post my findings to help someone else.I have have only tested this on a Raspberry Pi 3 running Debian Jessie, but it may work on other versions and flavors.Strong recommendation: Do not bother downloading the so-called "driver" noted in various places. The version for Debian Jessie is really just a script that copies configuration files (that seem to have some errors) into your /etc/ directories that brick your device. Happily, there is no need to do this, you can easily modify the files yourself.Prior to connecting the new display, do the following:The only software you need is for the touchscreen. You can get this with "sudo apt-get install xinput-calibrator"Then edit /boot/config.txt to add the following lines:----------------------------------------------------------------------------------hdmi_group=2hdmi_mode=1hdmi_mode=87hdmi_cvt 800 400 60 6 0 0 0dtparam=spi=ondtparam=i2c_arm=ondtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900 <======Note this is all on 1 line!dtoverlay=w1-gpio-pullup,gpiopin=4,extpullup=1----------------------------------------------------------------------------------Shutdown the pi, and connect the display. When you power it back up, you should have a perfect display. You can now calibrate the touchscreen by running Menu-->Preferences-->Calibrate Touchscreen. Click each of the four targets when requested and then you will get a text window which explains what you should put into a calibration file. For the Pi, the filename should be /usr/share/X11/xorg.conf.d/99-calibration.conf.And presto, you are done. I bricked my Pi 4 times getting this figured out...it is silly how easy it is once you know what needs to be done.Good luck!

When working with my Pi I found that I had a couple of choices -- plug a full blown monitor into it which didn't make it portable, or add code to it so I could remote into it from another computer. I wasn't ready for the latter, so I picked up this monitor. I found it easy to plug in, but relatively difficult to get to work with the Pi. Thankfully after combining instructions from multiple Amazon reviewers I was able to get it work. Here's what I did:In the file /boot/config.txt add the following text to the end of the file:#increase HDMI signal strengthconfig_hdmi_boost=4#remove black bordersdisable_overscan=1#set specific CVT modehdmi_cvt 800 480 60 6 0 0 0#set CVT as defaulthdmi_group=2hdmi_mode=87dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900dtoverlay=w1-gpio-pullup,gpiopin=4,extpullup=1Save the config file and then do this:sudo apt -get install xinput-calibratorThis took me a lot of trial and error to get working. After starting from scratch a few times, i started backing up my SD card after every successful step so that rolling back something I screwed up wouldn't be so costly because I would have to undo everything.In the end, this works pretty good. The monitor works well as a monitor but the touch screen part of it is a little touch and go - I don't think it's quite as precise as I would like it. However, for the money it's a pretty solid value.

Hardest part was figuring out how to mount it. It is very plug and play for a second monitor inside your pc case. I had to mount mine portrait for time being. Its perfect though for my weyland yutani pc theme. Just be sure to have a micro usb cable to a molex usb mobo connector for it or at very least have a usb mobo adapter with a 9 pin male molex plug in. Then get a micro usb to 9 pin female molex cable. Theyre like 5-7.00 prime on here. Get a short hdmi cable as well to run to your gpu. That should be all you need. If you want to mount it you do need to get a backing of some sort to bolt flush to the case inside. Only snag I hit but besides that its perfect.
