Need real power consumption data
The M5stack is interesting but many details and specs are missing. Perhaps the makers can help:
- what is the power consumption when OFF ? Does pressing the power switch twice actually shut the device OFF -> power is zero ?
- what the power consumption in deep_sleep ? I get variable amount from 17 to 40mA using a USB power meter with no battery.
- Is is possible to measure battery voltage ?
The M5stack is a battery powered device but very little support exists for conserving battery power, saving power, and estimating remaining battery life.
0.29a switched off.
0.39a running factory test.
Using a USB power meter.
to measure battery you need a test meter
Can't measure this tonight as cant find small allen wrench.
Does anyone now have any updates on this question? It would be really helpful to get some more info.
I haven't had the budget to buy anymore items to test but I'm just using a cheap inline usb power meter.
MKI camera = 0.1A
MKII (PSRAM) camera
Standby = 0.1A
connected = 0.14A 00592mah
Running a lot cooler then the MKI
I don't have anything else to test so that's all I can give.
Measurements taken with a Keweisi branded usb test meter.
