Hi everyone,
This may not relate to this topic directly. but I think I may get the response I am looking for.
I am running some Arduino ATtiny85 modules, and have decided to power them with a 2.5v Solar Cell via a 500F Super Capacitor. I did a voltage test on the components after assembly and I have noticed a significant voltage drop when hooked up to the Super-Cap. See attachment.
I am a novice at Arduino and Electronics and bemused with the drop in voltage when providing power to the Super-Cap.
With the Super-Cap disconnected I am getting 2.37v from the Solar-cell and 2.34v at the Schottky Diode. With the Super-Cap connected I get 1.13v at the Solar-cell and 0.73v from the Diode to the Super-Cap.
I can understand the voltage drop after the Super-cap, but can someone explain why I see a large voltage drop at the Solar-cell with the Super-cap connected?
Cheers,
Lance
