RTC backup battery on ELS61 | Thales IoT Developer Community

December 14, 2021 - 4:41pm, 911 views

I'm using an ELS61 module and I have to add a backup battery for the RTC. The documentation says that the maximum voltage on VDDLP pin is 1.9V, so I should use a 1.5V battery, that is not a typical value for RTC.

Can I have a more detailed documentation, and possible an application schematic?
