Yeah, this is maybe the 3rd time I've been on IRC, I guess I've given up trying to get it to work on my phone. Some of it's interesting reading. I'm alan01346 on there.
Page 8, "Fig. 1-1 RK805 One Battery Cell Application" is what I meant. I suppose it's possible it works but most people don't use it so it isn't well documented. Even in fig 1-1 I can't tell where the battery is. It has a sleep mode and an alarm. Page 19 (by xpdf) shows registers for seconds, minutes, hours, etc. More on page 21-26. I searched the IRC for battery and found: 26/12/17 01:37 <tl_lim> I can provide circuit how to add 3V battery power to existing schematic for RTC power 28/02/18 21:23 <Xalius> the white connector is for the RTC battery Maybe it used to be there, maybe the Pine64 has one, I don't know. Not sure what I'd use it for, power consumption seems too high for a portable. But if it's got a clock it makes sense it should have a battery connector.
