(TECH) Minimal power suply

Dear All,

I am powering module only using PIN 3+6. Module works only, when powered 4.1-4.2V, otherwise the module sometimes restarts. What are the power consideration when powering without battery, e.g. capacitors, etc.?

Thank you

Jan

Thank you for the reply.

Even with the battery connected, i still have problems when there is voltage on battery below 4.1V. I’d like to have this module in kiosk to do a call on a button, but it seems to me, taht this is not possible, with RePhone module… :frowning: The behavior is little erratic :frowning:

It just restart when you make a call?? or it restart when there is no SIM?
