Yea, I understand the China clone thing. I deal with it all the time unfortunately. I’m assuming your PCB manufacturing is “local” to the US 😉 Anyway, I had originally bought one as an Xmas gag gift for my brother-in-law who liked the clock until we realized that it was just pulling time from memory (ie, power outs caused a skew) hence why we started hacking into the device and adding a Real-Time-Clock as one of the items. Also did some software cleanups in a few areas but then wasn’t sure what to feed back if anything as they mostly were to deal with our mods and moving all the switches to an R-2R layout instead of one port per switch 🙂 loads of fun with an exacto and cutting traces…

I get the China thing too… the DS3231 I am using was from AliExpress… $2 per board… Somethings are hard to not use. Fortunately its really hard to screw up the DS3231 boards. You only have to worry about knockoff chips themselves that aren’t actually temperature compensating. Come to think of that… I can pull the actual temp off of one of these… hmmm…
