DeepSleep Shield & LoPy
I have connected DeepSleep Shield and Lopy without! the expansion board and I get 0.500mA in deep sleep.
Is that OK? How can I get uA?
import pycom import time from deepsleep import DeepSleep from network import WLAN wlan = WLAN() wlan.deinit() ds = DeepSleep() pycom.heartbeat(False) for cycles in range(1): # stop after 10 cycles pycom.rgbled(0x007f00) # green time.sleep(5) pycom.rgbled(0x7f7f00) # yellow time.sleep(1.5) pycom.rgbled(0x7f0000) # red time.sleep(4) ds.go_to_sleep(20) # go to sleep for 20 seconds
Also measuring over 500 uA with a LoPy + deep sleep shield, which is a shocking amount of current.
To continue using the LoPy, i have had to use a humungus sized battery (6600 mAh) and shorten the life-span of the device.
Please fix this pycom guys. This has taken far too long!
I like the LoPy, but if this is not fixed pretty soon i will be forced to switch to a low power arduino alternative.
I also have 520 uA (with the DeepSleep Shield and no expansion board) with a Wipy 2.0 (instead of few uA)
I am doing power comsumption test with LoPy and Deep-Sleep Shield too.
The LoPy firmware is 1.8.0.b1 and the DeepSleep library from Github has been modified 3 days ago.
I am doing the test with a power supply and a tester in series.
With the expansion board, the device uses around 620 uA.
Only with Deep-Sleep Shield I am measuring 520 uA.
Even power down WiFi and Bluetooth, the power comsumption is the same.
What I am doing wrong?
On the other hand, power comsumption for Pysense and Pytrack in deep sleep mode are better, around 9 and 17 uA respectively.
Noone can answer if the deep-sleep board is using 500uA during sleep? or 10 uA (as described) ?
