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: > **[Set Up on Raspberry Pi/Ubuntu/Kali/Homebridge OS — SunFounder Pironman 5 ...](https://docs.sunfounder.com/projects/pironman5/en/latest/pironman5_max/set_up/set_up_rpi_os.html)** I’m able to see the dashboard at: [http://192.168.1.99:34001/](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 25/09/14 10:11:18.970 [INFO] 25/09/14 10:11:18.970 [INFO] ############################################################ 25/09/14 10:11:18.970 [DEBUG] Config path: /opt/pironman5/venv/lib/python3.11/site-packages/pironman5/config.json 25/09/14 10:11:18.970 [DEBUG] Pironman5 version: 1.2.18 25/09/14 10:11:18.971 [DEBUG] Variant: Pironman 5 25/09/14 10:11:18.971 [DEBUG] Config: {‘system’: {‘data\_interval’: 1, ‘rgb\_color’: ‘#0a1aff’, ‘rgb\_brightness’: 50, ‘rgb\_style’: ‘breathing’, ‘rgb\_speed’: 50, ‘rgb\_enable’: True, ‘rgb\_led\_count’: 4, ‘temperature\_unit’: ‘C’, ‘oled\_enable’: True, ‘oled\_rotation’: 0, ‘oled\_disk’: ‘total’, ‘oled\_network\_interface’: ‘all’, ‘gpio\_fan\_pin’: 6, ‘gpio\_fan\_mode’: 0, ‘debug\_level’: ‘INFO’}} 25/09/14 10:11:18.971 [DEBUG] Device info: {‘name’: ‘Pironman 5’, ‘id’: ‘pironman5’, ‘peripherals’: [‘storage’, ‘cpu’, ‘network’, ‘memory’, ‘history’, ‘log’, ‘ws2812’, ‘cpu\_temperature’, ‘gpu\_temperature’, ‘temperature\_unit’, ‘oled’, ‘clear\_history’, ‘delete\_log\_file’, ‘pwm\_fan\_speed’, ‘gpio\_fan\_state’, ‘gpio\_fan\_mode’], ‘version’: ‘1.2.18’, ‘app\_name’: ‘pironman5’} 25/09/14 10:11:18.971 [DEBUG] PM\_Auto version: 1.2.12 25/09/14 10:11:18.971 [DEBUG] PM\_Dashboard version: 1.2.10 25/09/14 10:11:18.995 [DEBUG] Initializing OLED 25/09/14 10:11:18.997 [ERROR] I2C is not enabled. ls /dev/i2c\* returned: /dev/i2c-13 /dev/i2c-14 25/09/14 10:11:18.998 [ERROR] Failed to initialize OLED 25/09/14 10:11:18.998 [ERROR] Failed to initialize OLED 25/09/14 10:11:18.998 [ERROR] SPI not enabled 25/09/14 10:11:18.998 [ERROR] Failed to initialize WS2812 25/09/14 10:11:18.998 [DEBUG] Initializing FanControl 25/09/14 10:11:18.998 [DEBUG] Update gpio\_fan\_pin to 6 25/09/14 10:11:18.998 [DEBUG] Update gpio\_fan\_mode to 0 25/09/14 10:11:18.998 [DEBUG] Init GPIO Fan with pin: 6 25/09/14 10:11:19.031 [ERROR] GPIO Fan init error: ‘GPIO busy’ 25/09/14 10:11:19.032 [WARNING] GPIO Fan init failed, disable gpio\_fan control 25/09/14 10:11:19.032 [DEBUG] Init PWM Fan 25/09/14 10:11:19.050 [DEBUG] FanControl initialized 25/09/14 10:11:20.158 [INFO] SPC peripheral disabled 25/09/14 10:11:21.262 [INFO] Setting debug level to INFO 25/09/14 10:11:21.262 [INFO] PM Auto Start 25/09/14 10:11:21.262 [INFO] PWM Fan is supported, sync all other fan with pwm fan 25/09/14 10:11:21.262 [INFO] PMAuto started 25/09/14 10:11:21.345 [INFO] Influxdb is ready 25/09/14 10:11:21.347 [ERROR] [Errno 98] Address already in use Traceback (most recent call last): File “/opt/pironman5/venv/lib/python3.11/site-packages/pm\_dashboard/utils.py”, line 4, in wrapper return func(self, \*args, \*\*kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/opt/pironman5/venv/lib/python3.11/site-packages/pm\_dashboard/pm\_dashboard.py”, line 454, in start self.server = make\_server( **host** , **port** , **app** ) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/usr/lib/python3/dist-packages/werkzeug/serving.py”, line 868, in make\_server return BaseWSGIServer( ^^^^^^^^^^^^^^^ File “/usr/lib/python3/dist-packages/werkzeug/serving.py”, line 711, in **init** self.server\_bind() File “/usr/lib/python3.11/http/server.py”, line 136, in server\_bind socketserver.TCPServer.server\_bind(self) File “/usr/lib/python3.11/socketserver.py”, line 472, in server\_bind self.socket.bind(self.server\_address) OSError: [Errno 98] Address already in use 25/09/14 10:11:21.354 [INFO] PmDashboard started I also tried to remove the whole github pironman5 and do a complete new install.

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 ---

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. ---

First, you can check if jumpers are placed correctly on board. ![Screenshot_20250914_100322_Chrome](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/2X/7/7bc572f3ed455056dd0e15dec159e773c7aedbaa.jpeg) Did you get any error during pironman5 software installation? ---

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

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. ---

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](https://docs.sunfounder.com/projects/pironman5/en/latest/pironman5_max/faq.html#nvme-pip-module-not-working) ]. 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.

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.
