Steve Hicks posted in a comment on http://envirodiy.org/topic/seeeduino-stalker-v3-0-discussion/ some details about the new and the old version of the Seeeduino Stalke. You find the official information for the board's v2.3 under http://www.seeedstudio.com/wiki/Seeeduino_Stalker_v2.3 and the new v3 under http://www.seeedstudio.com/wiki/Seeeduino-Stalker_v3
I thought the v3 is an improvement but I read in the comment nearly only downsides: No temperature compensation in the RTC ("good" DS3231 in the old version, "bad" DS1337 in the new). And some would report "5 times more power in sleep mode than the previous boards"!!
This would be really a huge downside for my project--a bee hive monitoring solution!
Can someone pick up this (or other) point of criticism. Is the "bad" DS1337 much more un-precise than the DS3231 especially with a huge temperature difference. In case this is so, I do really not understand Seeed! It's a tool especially for outside data logging, why was it made worse by an update??!
It's the same with power consumption. Did you see much differences between v2.3 and v3?
