Before connecting

The exact RTC chip, pinout, supply voltage and battery-charging circuit are not confirmed from this view. Verify these details before selecting a library or connecting power. Check the battery requirements before fitting a cell; do not use a non-rechargeable cell with an enabled charging circuit. The photographed battery does not establish the battery supplied with the module.
