Reviews

A power management module from M5Stack including a battery charger and an RTC. The module also has a boost and a buck converter that convert the battery voltage to 5V and 3.3V, respectively. The specifications in the table below refer to the boost converter, the output voltage of the buck converter can drop below 3.3V when the battery voltage drops. Finally, the module has a number of options to (temporarily) turn off the outputs completely. See the linked page below for more information on that.
