Remote switch tail board with FET, so no added resistance

You can use a 4.2V supercapacitor, or 3.3V supercap with 3.3V LDO or a 3.7V rechargeable button cell with bleeder

But the 20 cent button cell should last for several 100 hours you push the button, and it is as expensive as the shottky diode

I had just started thinking about FET + super capacitor, but you are way ahead of me.

I will make it open source when I have tested it

I have a diode on the board which supports supercap charging from a bleeder, but a 15 cent battery should last hundreds of hours continuous on

I want to make on topic with my boards I have shared on Oshpark The updated TA drivers are still pending as I want to test them before they get public All build drivers can be bought in my sale topic or PM me .
