Thank you Mark and Olivia for your contributions. Your information is correct and valuable … however you both seem to have missed that this thread is about those microcontroller development boards which have on-board LiPo BATTery connectors, such as the DFRobot Firebeetle range.
As Olivia points out, connecting the SPM’s output to the Firebeetle’s BATT connector means the firebeetle is measuring the regulated output - not the actual battery voltage … and therefore totally defeats the point. And worse, paying extra for functionality which cannot be used.
Jane, am I correct in assuming that VOUT of Solar Lipo Charger (3.7V) (DFR0264) would be ideal to connect to Firebeetle’s BATT connector ? DFRobot’s wiki states “VOUT: Lithium-ion battery output. Connect your electrical equipment to it”.
