Max Sensor Power Consumption
rvdvoort:
What is the max power I can draw from a Mcmodule 110 "high" digital pin when the sensor is connected to external battery of 3.3 - 3.5 V. The sensor I have in mind would pull a max 15mA when in use.
Thx,
Rvdvoort
mc-Josh:
The maximum power that can be drawn from an I/O pin is 5mA for the mcMod110.
rvdvoort:
Thanks for the feeback but 5 ma is not enough. I might be able to go below 10 ma (around 8 ma)
Would it be possible to use 2 or 3 pins of the Mcmodule 110 in parallel to support the max of 10 ma. Would need this power only for a couple of seconds befor switching the sensor Off.
mc-Josh:
You may be able to use 3 pins in parallel, the maximum recommended draw for the microcontroller is 5mA per pin to a total of 15mA for the entire device.
kristofferis:
Is it the same recommendation for mcModule 120?
