Internet of Things (IoT) is a romantic marketing term created in recent 2-3 years.
There is no criteria nor standards on the IoTs. Some will rebrand a product existed for many years (way before IoT days)
as IoT to "catch the wave".
However, what I can say is lots of IoTs are cheap and sub-standard in many ways.
Cheap and quality go opposite ways.
Omega is not really a solution if you plan using it with other power source than USB adapter.
I would recommend going for the AVRs and if you need for example Wi-Fi, you might consider connecting AVR to ESP8266 and so on.
Properly prepared AVR-ESP stack can be ran on standard batteries for many weeks, even months (of course it strictly depends on your project).
If you look at the topology of the Adafruit design, the power to run 5v loads has to come from first being regulated down to a plausible battery voltage, and then boosted back up. That particular board is made with components that try to support a lot of current through that path, and warns that the upstream supply needs to be quite capable to match what the board can do.
But that kind of regulate and re-boots topology, if done with lower rated components, could easily explain the kind of issues seen here, in that it can impose a bottleneck on how much power can get from the USB input jack to the USB output one. We still don't know what is on the powerdock and how it is configured, but it's not hard to imagine limitations there.
@Chris-Stratton I'm not sure it is power but not really sure how I can test that? Currently it is drawing the power and serial via my MacBook Pro's USB port, if I power via a PSU I lose my serial connection to trigger the upgrade at all.
I did also try ensuring only the upgrade file was on the stick, it's very odd that the 4GB isn't working but the 128GB is. I am going to try and find a major brand smaller stick, Sandisk or whatever, just in case the stick itself is oddly configured/designed.
Any suggestions for how to test things are appreciated!
Well, After purchasing an external active antenna it looks like there is possibly an issue with the antenna on the gps board.
the active antenna is currently sitting on my desk in the middle of our office (nearest window 15 feet away) and it is now seeing 11 satellites on the u-blox test software. Now to try this on the omega itself.
@WereCatf so basically all of the 3.7V LiPo batteries found here can be used. Surely a low Ah model will last few but will charge faster than a bigger one. My concern is about the charging current available: if I use an high Ah model, my power dock will charge it without overheating?
It's not the capacity that determines the charging-speed, it's the charging-circuit that does. A 500mAh battery will charge at the same speed as a 2000mAh one, so it'll just simply take longer for the bigger battery to get charged full. That is to say, you could safely slap a 20,000mAh battery on it, if you wanted to :smirk:
@None-None nice. i will take a look at the whole circuitry when im back from holidays in 4-5 days!
But my first guess would be that (although i havent looked into its circuitry) that the protection circuit also discharges the battery? because normally you want them to be at ~70% of their load when storing them
