Noted – we'll plan to use the STM32L010K4 as the microcontroller and the SIM7070G for GSM/GPS.
Power Management:
For charging your 1S LiPo battery (500mAh) from both solar and USB, would you like to include a dedicated charging/regulation IC (for example, one that provides boost regulation to a consistent 3.3V and handles charging control), or do you plan to design that power path separately?
Please let me know your preference or if you’d like me to assume a common approach (for example, using a combined charger and boost converter stage).
Understood – you'll need a power management block that takes the LiPo (3.0–4.2 V range) and provides both a regulated 3.8 V rail and a stable 3.3 V rail.
Regulation Architecture:
Would you like to use dedicated regulator ICs for each rail? For example, a buck-boost regulator to deliver 3.8 V (to cover when the battery is below or above 3.8 V) and a buck converter for the 3.3 V rail (for the STM32L010K4 and logic)? Let me know if that approach works or if you have any alternate ideas/preferences.

A circuit for a gps tracker using stm32f103c8t6 and sim 808, that acquires and sends gps coordinates to a separate interfaced application. The circuit will be powered by a 12v dc battery so there a need for power regulation. there is a USB type micro B for code uploading.
