Hello Guys,
I am trying to come up with a power system where I have 3 super capacitors, one attiny45 and 3 solar panels. I want the supercaps to get charged accordingly from the solar panels with over charging protection and some other safety measures and then deliver a constant clean 5V to some modules.
The things I have in hand now / The things I want to utilize for this project:
1. https://www.arrow.com/en/products/xv3550-2r7307-r/eaton - 3 Pieces
2. https://my.element14.com/microchip/...tiny-20mhz-dip-8/dp/1288352?ost=ATTINY45-20PU - 1 Piece
3. https://www.aliexpress.com/item/32861874199.html - 1 Piece
4. 5V 250mA 1.25W Generic Solar Panels - 3 Pieces
Do I need some sort of Buck/Boost convertor to get a constant 5V from those 2.7V supercaps? If discharged completely they might have almost 0V in them. What is the proper way to do this setup?
Help me out guys.
Thank You.
