Can I use and external power supply and USB at the same time

Yes, 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.

6 FAQs about [How to connect the microcontroller to the battery power supply]

Does a microcontroller use a lot of power?

However, 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.

How do I charge my MKR WiFi 1010 battery?

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.

Does a microcontroller read a voltage signal?

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.

How much power does an ESP32 microcontroller need?

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.

Does a microcontroller have a ground?

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.

How many Ma is a standard battery supply?

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.
