LoPy+Expansion board+Deep Sleep Shield only down to 18mA
I have been experimenting with the Deep Sleep Shield, expansion board and a LoPy and trying to get the sleep working at as low a power consumption as possible. So fare I'm only able to get to 18mA. This is by using the example code for the Deep Sleep from the Docs and with
But I still can reproduce what other people on the forums have. Anyone got any ideas?
With the deep sleep shield and library, the lowest I have been able to get is 604 uA (not plugged into USB)
On wake, tranmissions in LoRa are around 150 mA with an 'on' state of 40 mA.
Wake up, send transmission, sleep.
@jcaron I got the time to test this today and you are correct. Got the 600uA in deepsleep. Thanks for the help :)
@Lokefar I believe the lowest power consumption is only achievable with a battery connected via the LiPo connector, someone else may be able to confirm.
@jcaron Yes, that's the one.
I am using a USB cable hooked to a powerbank. On the USB cable I have attached the power measuring.
@Lokefar are you using the example here:
Also, are you measuring from battery or over USB or...?
