I am using a Sodaq one V2 board to make a solid single button gps logger. I’d like to have the pushbutton to be an on/off button.
For this, i have attached a momentary switch between battery + and the “external_switch” pin.
Power enable works great, however reading the external switch using SWITCH_SENSE / pin 23 does not result in anything. I also found that the switch_sense label and 1M/3M have been omitted from the schematic. Does this mean that it is no longer possible to readout the external switch position?
I’m sorry to say but the Switch Sense functionality has been removed in V2 of the SODAQ ONE.
This is mainly because we saw that nobody (just you) used the on/off switching feature as it was intended (using a momentary switch) but every one used latch switch instead.
Since we had to put in a voltage divider (since we are switching VBAT), this caused a constant current to flow which people didn’t like, so we removed it
Hi Jan Willem,
Thanks for the response. I have attached the necessary circuitry externally to one of the external pins. And i will take caution to detach the battteries when the device is not in use for longer periods of time:-)
