nanoQ 0903 hardware update

yes it is hardware fault
I was measurement a current for RTC and I received 35 mkA. The datasheet for NT96655 talk what a typical current for RTC is 1 mkA

Who eats 34 mkA?
P.S. For measurement I cut a wire for to charge RTC accum.

Hi @Rayman.Chan, could you explain more deeply the current schematics upgrade?
May be you have some pictures of mini 0903 with real upgrade?

Thanks.
 
Hi Gosha,
this is the schematic of the RTC battery mod for @popesych for reference
 
Does the capacitor version require any similar hardware modification?
 
I found in my mess a capacitance, like in here
I replaced a original battery to it. Will try to check how it can save a clock.

P.S. I going to disconnect a WiFi power pin. May be a source a noise, who damage signal from GPS satellites, is a WiFi
Does it work my friend
