here is a close up of the #Palm M125 "capacitor/battery“. I has printed
3.3v 0.22 F on it (sorry I am not an expert in this)
Where can I get this?
@inlovewithpda looks like there's some that look very similar https://eu.mouser.com/c/passive-components/capacitors/supercapacitors-ultracapacitors/?q=supercapacitor&capacitance=220000%20uF&voltage%20rating%20dc=3.3%20VDC
@inlovewithpda (you can check the physical measurements on the datasheets)
