I'm doing an IoT solar sensor for a project which uses an Arduino nano 33 BLE powered by a battery and the solar panel. I was looking for a device that regulates de charge of the battery through the solar panel and the Arduino power given by the battery, just like Solar Manager 5V. (Link of the product https://www.dfrobot.com/product-1712.html )

The solar panel has a 1W of power and is desinged to work at 5V. This product fits perfectly to my solar panel, however it has an output of regulated 5V and the Arduino works with an Vdd of 3.3V. I don't know if you have a product similar to Solar Power Manager 5V but also capable of provide regulated 3.3V instead of 5V in order to feed the microcontroller, or idk if it would be better to use Solar Power Manager 5V with a Buck converter or voltage regulator to transform 5V from the power manager to 3.3V to Arduino.
I need to minimize power consumption too.

Greetings and thank you for your help.
