Hello,

I'm currently working on connecting my StromPi 3 to my Raspberry Pi, but I'm looking for a way to do it without directly plugging it onto the Pi. Could you please provide me with instructions or guidance on how to achieve this?

Thank you very much for your assistance.

Best regards,

Hello,
to use the StromPi3 with a Raspberry Pi without plugging it onto the Pi, you need to connect both 5 V pins and at least 2 ground pins. In addition, GPIO pins 14 and 15 are required for serial communication. It is important to ensure an adequate cable cross-section. However, the StromPi is not intended for this application and the additional plug connections will result in voltage drops, which will probably lead to undervoltage messages and possibly unwanted behavior.

Hello,

Thank you for your response.

I appreciate your guidance on connecting the StromPi 3 to the Raspberry Pi without direct connection.

The reason I'm asking is that I'm interested in using your product ARMOR CASE "BLOCK ACTIVE with both the Raspberry Pi and the StromPi.

I have another question regarding the GPIO usage. Since StromPi 3 utilizes GPIO pins from the Raspberry Pi, I was wondering if it's possible to still use the GPIO pins provided by the StromPi 3 while it is connected to the Raspberry Pi.

Thank you.

Best regards,

Hello,
each GPIO pin is routed through on the StromPi and can be used. With the exception of GPIO 14 and 15, these pins are used for the communication between StromPi and Raspberry Pi and cannot be used for any other purpose.

Hello,

If I want to use the Strompi 3, I cannot use a fan, and this poses a problem for me. Could you also provide information about the battery lifespan, autonomy, and the processor temperature when using the Strompi and the battery?

Thank you.

Hello,
the small battery lasts for approx. 1 hour and the large one for approx. 2 hours. This is of course heavily dependent on the load.
The StromPi can independently detect the loss of the primary voltage source and switch to the secondary. It then shuts down the Raspberry Pi and switches itself off after a set time. When the power supply returns, the Raspberry is automatically restarted. There are also various interval and alarm features that allow the Raspberry Pi to be powered up and down at specific times.
The temperature is also highly dependent on the load. Depending on the application, it must be decided whether additional cooling is necessary or not.
