Reddit reviews DS3231 Real Time Clock Module 3.3V/5V with Battery for Raspberry Pi and Arduino by Atomic Market

Sure, I have a different ds3231 module as well but it shouldn't matter. Just in case, this is the one I used - https://www.amazon.com/gp/product/B01M105UFC/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

Thank you kindly for the response, sir. I have this DS3231 real-time clock module from Atomic Market and it's been working out pretty well. I was apparently too dense to realize that the Pi-hole DNSSEC checkbox was redundant on top of Unbound. That has now been resolved and I'll hope for the best.

And I believe the drivers to be active,

Should I have ntpd installed, as well, or will my device(s) be able to accurately pull the correct time from my router, which has a series of four NTP servers configured, running: ntpd [email protected] ?

EDIT: My router tends to get out of sync. I believe this to be due to the fact that the /etc/resolv.conf file is changed back to 127.0.0.1 after every reboot by Vyatta so it loses the ability to access the outside world. It's SUPPOSED to redirect queries to DNS1/2, but that's not possible without the basic configuration in place (which is only important for me to change when I need to make updates, or run patches/fixes on the device). Updated manually, repaired the ntp servers and enable "iburst" for fast time sync and all seems to now be well. Thanks for your assistance. Will make sure I have a couple more NTP servers on the network to avoid this in the future.

> 4) is there a telegram chat for users? If not, should I set one up? I'd love to be able to chat about the gamey end of things in tg.

They're using Slack to communicate with the community. Some folks wanted Discord, others prefer Telegram, but Slack is far and away the most professional, IMO. It's great to have so many excellent options for support, but does come with its own complications.

Sorry I'm not a ton of help with your other questions... I'm pretty new to this experience and I'm fumbling around without an e-ink display. Once upon a time I added this RTC to my RPi3B+ for a Pi-hole, Unbound & Wireguard build, but the downside is that there's the additional requirement of a battery to keep the clock accurate. Perhaps something similar to this would be a better fit for you, but I'm just taking wild guesses at this point: https://www.amazon.com/dp/B01IP5MP72/

I've also struggled to get Bluetooth working from my Android device. Good luck, keep at it.
