This is a small board (2 x 3 cm) capable of 8 - 45 V input. It gives output of 4.2V. Features: PowerPath Management with automatic switching between input and battery. LiPo charger. Wide input voltage. High efficiency. This is the first revision, looking for suggestions and feedback. Hardware Used: XL2011 - XLSEMI MP2617 - MPS (Monolithic Power Systems) Uses: This project can be useful in automotive applications where a device has to run of a single LiPo and/or vehicle battery. ESP32 projects with GPS or GSM modules are a good fit. It can handle 12V or 24V battery input which is the most common battery configurations, can even handle 36V in most circumstances. 12V Battery - Charging Voltage 14.4V 24V Battery - Charging Voltage 28.8V 36V Battery - Charging Voltage 43.2V Most GSM modules run on 4.2V and this project aims to handle that. ESP32 with a good LDO like HT7830 or HT7833 can handle ESP voltage and current requirements running at 3.0 or 3.3 V respectively.
