Hi
I wold like to know if there is plan to support Picar-x with Raspberry PI5? My other question is if Raspberry PI5 is HW compatible with Picar-x even if software would not work.
Regards Uroš
The pi 5 can work with picar-x.
It’s just that when pi 5 itself is working, the IC temperature is relatively high, so we need to install a cooling fan, if we install a cooling fan, our robot hat can’t connect GPIO with Raspberry Pi 5, so we are currently working on the robot hat upgrade. Please be patient.
If you remove the cooling fan, it is possible to work with picar-x. But you should also understand that the speaker is just above the Raspberry Pi IC, and the heat from the IC may have an effect on the speaker when the Raspberry Pi is working.
Thank you for quick replay and detailed explanation. I can see where is the problem now and I will wait for hat upgrade
Regards Uroš

Hello, I’m trying to use Picar with RPi 5 and I have a fan. Wht’s the progress of solving that problem?
You can use GPIO adapter this adapter provides extra space for coling and RPI works with PiCar-X with put a problem.
You shoud know that everythig works with RPI5 except EzBlok image which is incompatible with RPI5.

What karneki said is correct.
You need a GPIO adapter to increase the internal space between the Raspberry Pi and the robot hat, and then the Raspberry Pi’s cooling fan can be installed.
Aside from the EzBlok image that is not compatible with the RPI5, everything else can be used in conjunction with the RPI5.
I’m also keen on making the Pi5 work with the picar-x 2.0 kit. The following seems to be true as of the time of this writing (2024-Aug-21):
The assembly instructions for PiCar-X 2.0 suggest that version 2.0 of the kit contains a variety of optional standoffs of different sizes, the exact ones to use depending on the Pi you’re going to use. For both Pi5 and Pi4, it’s now suggested you use 30mm-length standoffs, instead of 11mm, between Pi and HAT. This makes the robot HAT sit further away on top of the Pi, which in turn should allow a low-height cooler, such as the Raspberry Pi Active Cooler (for the Pi5), to be employed. Moreover, with the HAT sitting higher, the airflow and the fan’s effectiveness is just better. The same instructions list a “40 pin header” as part of the kit, which is only used in these precise instances. This is adapter karneki mentioned and gave an aliexpress link to above. So, presumably, it’s now included, and so it seems not only that the 2.0 kit supports the Pi5 at the hardware level, but that you’re encouraged to give the Pi this extra breathing room even if you’re using Pi 4.
What the instructions don’t list, though, is what raspberry pi camera module is included, but indirect clues point to version 1 (5 megapixels). I want to use V3 instead, and make it work with the Pi5, with the Bookworm-based Raspberry Pi OS. I don’t know, however, if V3’s dimensions are different than V1 and whether they’ll be consistent enough with the C structural plate. I also can’t expect the included software to work out-of-the-box, but that’s part of the fun. If I get anywhere with the above, I’ll report back in this thread.
P.S.: by Raspberry Pi Active Cooler I mean this.
The V3 Raspberry Pi camera is not compatible with the Picar-X for assembly.
The dimensions of the V3 and V1 cameras have a slight difference.
