Hello everyone! I want to buy this module (https://www.amazon.it/HiLetgo®-decodifica-amplificatore-alimentazione-lossless/dp/B0797T1T87) and connect a 2W speaker to it that plays a song that I insert in the SD. I noticed from the picture that it is powered by "micro usb power supply". As this is a gift ... I want it to be portable and I want to connect the micro usb power supply to a small portable 5V battery (e.g. an alkaline battery).
(Moderator's note: Link to English version of the web page referenced above: https://www.amazon.com/KOOBOOK-Play...ule+micro+usb+5v+power+supply+,aps,389&sr=8-1)
Is this possible?
How is the connection made? I have lots of micro usb wall chargers (i.e. to plug into the wall socket), I was thinking of cutting the cable and see if I can connect wires to the + and - of the alkaline battery ... or something like this.
What type of battery do you recommend for this purpose? I've seen this classic one: https://eclats-antivols.fr/en/9v/17600-9vdc-alkaline-battery-duracell-1604-ultra-5000394005778.html ... in this link the battery is 9V but I need 5V for the module I use.
