Question: Good day, Can you please give some guidance on how to connect this particular module to the GPIO of the Raspberry Pi and into which pin what wire, if I would like to power the diode with 3.3v? He is a novice, and I would not like to damage the minicomputer by incorrect connection. Thank you in advance for your answer. Regards.
Answer: You can power the module with batteries, as shown in the diagram, and control the power supply with, for example, a relay connected to the Raspberry Pi:

Question: Good day, does this module work with Raspberry Pi i.e. will I be able to power the diode from the GPIO pins of the Raspberry using the attached cable? If so, in case both 5v pins are occupied e.g.: by a fan, will there then still be free pins to connect the board? Thank you in advance for your answer. Regards.
Answer: The selected module can be connected to the Raspberry Pi.
You can duplicate the Raspberry Pi's 5 V pin using, for example, an overlay: https://botland.com.pl/raspberry-pi-hat-ekspandery-wyprowadzen/2816-plytka-prototypowa-tht-raspberry-pi-4b3b3b2b-5904422365363.html
