In deep Sleep the cunsumption is below 19µA, but i have to send with PA_MAX. On some Windows the open/close frequency is verry high, so the battery is to fast emty.
The CR2032 is good, but i want more "lifetime"
I had the contact with this seller, but an international money transfer was needed and is expensive...
yeah, they also have a minimum order quantity and ship with DHL only, so you have to pay import taxes to EU
so it only makes sense if you order a big quantitiy and then try to resell it somehow
all in all a hobby that at least has some return on investment, compared to other ones i had :))
You're courageous th have gone on kickstarter, from memory seeedstudio nearly went down because of an error on a crowdfunding project and had to produce and ship (the more expensive par of it) a remlacement for the first batches...
ahh .. i didnt know this about them... and in their scale - i can undertand
it happened to me as well but in my scale it was rather a paid lesson :))))
