eeed lcd displays for raspberry pi factory

The official Raspberry Pi 7” Touchscreen allows you to add touch inputs to your programs, creating a new way to interact with your projects. It also makes for a fantastic desktop screen for day-to-day use of your Raspberry Pi. Wrap it in one of our screen cases and take it anywhere – events, Raspberry Jams or even just your friends house for a coding evening!

For smaller projects, LCD and ePaper displays are a fun way to add a visual element to your projects. With simple code and wiring, they’re great for projects that require text, menus and navigation.

I had the same problem using fan shim with RP4, Software boots up perfectly fine when you don"t have the fan shim. Switched the fan shim with a usb fan because I want both the LCD and fan on my raspberry pi 4, now it works fine.

I can confirm that the RP4 board is getting stock at booting and the LCD wont work properly if the Shim Fan is in place. It the Shim service try to start.

I recently ordered a new type LCD that is has an installed fan, this only made for the raspberry pi 4. Just tested it out with raspiblitz and I am able to boot up the software with no issues. Who ever has a raspberry pi 4, and want to have both fan and LCD on the pi then I recommend getting an LCD with built-in fan, this is just an option for the ones with RP4 and are having problems with fan shim, as well makes the whole raspberry pi set up look very clean.

You are !00% right. The connections on the fan are the main issue. The fan cant handle a HAT. Sometimes if the connectors are not well aligned the Pi wont boot. I am remove the LCD and using keeping only the fan. I rather keep the PI cool

This or similar LCD with fan and power-pins on the rear is for sale without the case, so if it"s the same size as other 3.5" screens it might allow other cases, for example the CryptoCloaks LightningShell: https://www.amazon.com/Raspberry-Resistive-Heat-Sinks-320x480-RASPBIAN/dp/B07VHQX37S

Yea, the case makes the pi run hot by keeping all the heat inside but I took out the case and just left the bottom half of the case, right now my pi is running at 47 celsius.

@gandreottola, good number! I think with any kind of active cooling the RPi4 is comfortable. Also it is very cheap to reaplace this kind of fan requiring only two pins (especially vs the shim fan.)

@fluidvoice The new screen is working straight out of the box. Doesn"t even need new drivers, just the one already installed. My broken touch function is alive too (probably my old LCD was broken). The fan is spinning, temp at 53 C. The fan is glued to the GPIO connector, but probably could come of if enough force or a knife applied.

I would try but my fanshim died :( I for an enclosed case with fan built on LCD, as expected it runs hotter than I like but not throttling. LCD works.

I turn it on and the LCD comes up to boot then half way in booting the screen flickers showing random parts of the screen with the boot sequence showing. No SSH possible.

Plymouth is causing problems. I have the same ahrdware as you and had the exact same problem as you. The Raspberry will boot eventually but this could take 20 minutes to 6 hours. The easiest way to tell is to watch the ethernet port lights (you will be able to ssh in when it is blinking). Once you are in, uninstall plymouth ( sudo apt-get purge plymouth* ) and all will be fine.

@openoms & @fluidvoice how was the testing of the LCD+Fan? Can we plan to update shopping lists for v1.4 release to that to reduce ShimFan connection problems?

I am still pro ShimFan (especially that now the flickering problem seem to have a software fix) manly because it does not run all the time. I have found it necessary during the initial Block Download, but during the day-to-day operation I prefer having the fan off for up to 70 degrees.

There are plenty of these appeared since the RPi4 came out: https://www.aliexpress.com/wholesale?SearchText=raspberry+4+heatsink+case . I am waiting to have one posted. and will do some tests.

I have tested with a GPIO Expansion board. Physically separating the connection of the shim fan from the LCD did not help my faulty one. Also unlikely to be an EM interference as distance form the board did not make a difference either.

the not shutting down is due to the bitcoind not quitting. The system will shut down if you issue the command with the "force" option though it will have issues booting later due to the need for the blockchain to sync properly.

Possible, but when I remove the faulty shim-fan the sudo reboot or sudo shutdown now works instantly. How would the shim-fan affect the bitcoind? Will test with force and update here. Still would be very strange to need that.

! got a new shim-fan today and unfortunately it produces the same problem so 2 out of 3 of mine are faulty (only the one from an early batch is ok) although there is no visual difference between them.

I know the pi cant power that voltage however, if I supply power with a different method positive and ground with a 12 Volts could that work? Does the (signal wire?)put that voltage back into the pi gpio?
