GPS, battery questions

[tve]

Hi, very interesting project and very nice execution and documentation! I have a couple of questions, if you don't mind (dunno whether this is the best place to ask):

• What made you conclude that the quectel module has lower power consumption than a uBlox M10? When I look at the datasheets I find them equivalent, with the caveat that I can't find voltages corresponding to the mA figures in Quectel's docs. In the end doesn't the acquisition time almost matter more than +/-1mA in the datasheet? Maybe you tested both side-by-side...I find the cloud locate feature of the M10 very attractive: it could be combined with periodic "conventional" fixes for geofencing. I don't quite understand the storage requirements, however (the uBlox docs are vague).

• Where do you source a 30mAh LiPO that weighs 0.55g? In one of the photos I see one that says NOVACELL 301012P but I can't find that on Nova Battery's site and an Alibaba listing only shows a version with protection board which weighs over 1g.

• Are you continuing to update this project or is it essentially archived?

Thanks much!

Hey, thanks for your questions. The M10 wasn't out when I started with the project. Might be a good alternative, but it definitely is significant more expensive. We get our 30 mAh LiPos from a German webshop: https://www.mikromodellbau.de/. Yes, the project is updated. We were running a lot of tests and will share results. Best

I look forward to an update! I just got an M10 module and hope to test the CloudLocate stuff. The datasheet and such are very vague... I wish there were more open source projects of this nature around! Thanks for the link to the LiPO. It looks like that model now incorporates a protection PCB and the weight is listed at 0.8g. Maybe you removed the PCB or got an older model without protection PCB?
