Does it work without battery only with USB power?

End-Of-Life Products & Services RePhone

I couldn’t get the answer from the wiki. It looks like a battery is required for the RePhone to work. When I connect it to USB power without a battery the LED is red.
It looks like a battery is mandatory. Is this correct?

Yes, without battery you can’t work.

Hi,

I found that the module can (in fact it is right now in front of my eyes) work without battery.

All you have to do is power the module with a good 3.3V power source. I have an old ATX power supply giving more than 3A and it’s working OK. Use pin 6 for GND and pin 3 for +3V and also connect me module to your PC (this is very important).

Now you can enjoy your module without a battery, even with a SIM connected seems to be working OK (i.e. I’ve been able to send SMSs).

Regards,
Roberto.
