(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


May be this two topics can help you!

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?
