Current absorption in sleep mode

Post by Oliver_TU »

Hello,

I have the problem that my Z-Uno is consuming to much current in sleep mode.
The specific sleep mode is "FLiRS" with a timer:

"
ZUNO_SETUP_SLEEPING_MODE(ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE);
.............
.............
zunoSetBeamCountWU(30);
zunoSendDeviceToSleep();
"
When measuring the current with an oscilloscope I get between 20 and 40 mA when awake and around 6 mA when sleeping with a 9 V source connected to the 7 - 18 V input pin.
According to the "Z-Uno-Quick-Start-Guide" the current consumption in sleeping mode is suppost to be "around 25 µA".
Are more commands needed to get to that level besides the "zunoSendDeviceToSleep()" command?

Regards
Oliver

When powering from 7-18 the consumption will be always big.
