@@SergesMike hi

[@harritronics360]

Thanks for this video.
I guest the capacitor is connected to the VCC of the PFO Ic which I often call the PA ic. Its terminals are connected to VBAT or VPH and GND. This is a clear indication that it's a decoupling or a smoothing capacitor whose job is mainly to remove unwanted noise or glitches and supply a nice smooth DC to the PFO ic.

[@SergesMike]

Exactly.
You are good at explanations
Thanks 🙏

Nice vidéo 😮😮, but the sound was a hindrance to the voice.I think doing it without the music would be good like the other videos.

[@SergesMike]

Oh cool bro
Some people can’t just follow with background music but it’s quite cool with that tho.😇
