Customer ServiceI''m using STM32F401RDT6 microcontroller which is powered during the day by a solar panel (power regulators converts the panel''s voltage to 3V3). The MCU uses its internal RTC for logs and the issue is to keep the RTC running from the low power mode during the night.
Customer ServiceYes, you can simultaneously connect external power supply and USB. As explained in one of the answers, that you linked, the Arduino chooses it''s power input through the supplied voltage on Vin/barrel jack. Vin has no direct connection to the VUSB, so the USB port will not get any voltage from the external supply, thus it does not get damaged.

Customer ServicePowering micro-controllers by Battery. Working with low-power applications, one of the most common topic are batteries. Questions like "Which one is the best battery?" is a very common one. We all know that there''s not a single answer for such question, and this post will explore the different options as well highlight the weakness and
Customer ServiceIn order to safely connect a battery or secondary power source to Pico, we can add a diode between the second power source and the VSYS pin. This will prevent one power source from back-feeding the other. Whichever power source has the higher voltage will send power to the Raspberry Pi Pico board.
Customer ServiceThat''s a good (high, multi-user appeal) question & I''ll attempt to guide via a "method" as opposed to "cookbook." You do "not" want to introduce any external voltage source to the output of your board''s 3V3 Regulator. (unless you''ve defeated the connection path from that regulator to the board''s 3V3 bus.)

Customer ServiceHowever, there is a way to reduce the amount of power required by the operation of the microcontroller. Microcontrollers often have built-in functionality that allow them to enter a low-power or “sleep mode”. While in this mode, the microcontroller will be consuming significantly less energy, but it will only perform very limited functions.
The first step is to connect the board to a source of energy, this can be your computer or a phone charger. In both cases there will be a cable that ends with a micro USB that goes into the MKR WiFi 1010 socket. A standard 500 mA supply is ok and will charge your battery in a number of hours that is proportional to the capacity of the battery.
In many cases, peripheral components of a system that require power will return signals that are read by the microcontroller (e.g. sensors). As we know, voltages are measurements of potential energy, so reading any voltage signal depends on a relative comparison.
Let‘s get started! The nimble ESP32 microcontroller chip needs stable power to operate. The key requirements are: Voltage: The ESP32 requires between 2.2V to 3.6V input voltage. 3.3V is optimal. Current: Depending on the application, current draw ranges from 10 mA in deep sleep up to 500 mA during WiFi transmissions or sensor readings.
In addition, there is a data signal between the microcontroller and the motor package that has a ground or shielding. Although we think of grounds as ideally $0V$, they are really just a reference for a relative measurement. Actually, there is a certain amount of voltage that does exist at a given reference ground.
A standard 500 mA supply is ok and will charge your battery in a number of hours that is proportional to the capacity of the battery. The circuit is designed to provide 4.2V and 512 mAh; with a typical C/2 charge/discharge rating of the cells, this is the reason why we suggest a 1024 mAh minimum capacity.
