Pironman 5 Max OLED display won't turn on

echo317 · September 14, 2025, 8:13am

Hi,
Since yesterday, proud owner of the Pironman 5 MAX.
CN0498D
2025 06 13

I have assembled all parts correctly. Followed manual and instructions (video) and YouTube.
The OLED display is not turning on. I have opened the case and re-assembled the OLED display to check if cables work correctly. Also the blue lights are not on after assembly.

Steps I have taken:

I’m able to see the dashboard at: http://192.168.1.99:34001/
But the OLED display and blue lights are not on. The two fans in the back of the case are spinning.
After reboot nothing.. then I go to: /usr/local/bin and did: sudo ./pironman5 start
I got the following output:
echo317@raspberrypi:/usr/local/bin $ sudo ./pironman5 start

I also tried to remove the whole github pironman5 and do a complete new install. Nothing.
I need some help please. Thank you.

Weirdyguy · September 14, 2025, 11:27am

Which OS are you using? Before installing pironman5 max Software, did you update the system? sudo apt-get update && sudo apt full-upgrade -y . Update the kernel sudo rpi-update . By looking your log file, it seems i2c not detected, sudo i2cdetect -y 1 . Did you install the latest python3 software?

sudo apt-get update

sudo apt-get install git -y

sudo apt-get install python3 python3-pip python3-setuptools -y

echo317 · September 14, 2025, 1:06pm

Ah, thanks for your reply. The i2x was indeed not detected.
Because it’s a Pi 5 new straight out of the box, you need to enable this by default.

sudo raspi-config
Interface Options
I2C > Enable

sudo reboot

After that the OLED display is working. I’m so glad! Thanks for your help. Now I need to figure out why the RGB led’s and fan are not on.

Weirdyguy · September 14, 2025, 2:05pm

First, you can check if jumpers are placed correctly on board.

Did you get any error during pironman5 software installation?

echo317 · September 14, 2025, 5:21pm

Thanks for replying, the jumpers are on, they were there by default. I don’t think I should change this right? Please see photo’s attacked.

All seems to be ok, well connected, RGB fans are spinning but no LED, same for LED mounted on board. Pironman5 board is well connected to gpio, no bending, no pin damaged. Which OS are you using? All updates are done : sudo apt-get update && sudo apt full-upgrade -y and sudo rpi-update than reboot.

SunFounder_Moderator · September 15, 2025, 3:50am

Have you set the FAN LED? We recommend you visit the dashboard and set the FAN LED to ON to enable it.

Fan LED: Set the RGB fan mode.
Off: Turn off RGB.
On: Turn on RGB.
Follow: Automatically turn on RGB based on the fan’s operating status.
From the images you provided, we noticed that the wiring direction of the FPC cable for your dual NVMe PIP module may be incorrect. We suggest you carefully follow our FAQ tutorial to confirm this: [ FAQ — SunFounder Pironman 5 documentation ].

If the FPC cable direction is reversed, it may cause the dual NVMe PIP module to not receive power, leading to the SSD not being recognized or functioning properly.

Thanks for replying to my message. I have changed the FPC cable as described. Unfortunately with no result. So back to the beginning, removed the SD card, complete new image reloaded to the SD card. Fresh install, then from scratch started again:
cd ~
git clone -b max GitHub - sunfounder/pironman5: Code for Raspberry Pi 5 case (Pironman5) --depth 1
cd pironman5

When I do:
cat /proc/device-tree/hat/product I get: No such file or directory.

After everything, I can safely say, that IO board is broken, included my acryl black window.
I have contacted the email address, hope the can ship me the replacement parts soon. This is crazy. It’s 100% warranty and production issue.

Spf650 · September 15, 2025, 6:30pm

Which OS are you using?

Just curious as to this statement

When I do:cat /proc/device-tree/hat/product I get: No such file or directory.

From memory, since Bookworm this moved this up to

/device-tree/hat

From the previous

/proc/device-tree/…

echo317 · September 15, 2025, 6:34pm

Hi @Spf650 thanks for replying, I given it another try;

~ $ cat /proc/device-tree/hat
cat: /proc/device-tree/hat: No such file or directory

Spf650 · September 15, 2025, 6:48pm

Which OS and version are you using?

If bookworm you should be looking in /device-tree not /proc/device-tree

echo317 · September 15, 2025, 7:31pm

uname -a
Linux raspberrypi 6.12.34+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.34-1+rpt1~bookworm (2025-06-26) aarch64 GNU/Linux

SunFounder_Moderator · September 16, 2025, 2:29am

The command you executed is incorrect.
After confirming that the IO expansion board is properly connected, please execute the command cat /proc/device-tree/hat/product to check if the Pironman 5 can be recognized. Please provide a screenshot of the command execution for our confirmation.
