Can the xiao esp32s3 be powered by 3.7v li batteries?

so far in the project ive been using the camera with a laptop so it was being powered through the usb c, but i saw on the website that it needs 3.8v to run. What battery do i use? I initially had a 3.7v li battery that i wanted to use.


When powering electronic devices, it’s important to match the voltage requirements as closely as possible. However, there is usually a certain tolerance for voltage differences.

In practice, a 3.7V lithium-ion (Li-ion) or lithium polymer (LiPo) battery should work fine for a device that calls for 3.8V. The reason being, when fully charged, a “3.7V” Li-ion/LiPo battery actually provides close to 4.2V. It’s labeled as 3.7V because that’s the average voltage output over the discharge cycle.

Hi there
This is working GREAT!

thanks everyone… ill be using the smallest 3.7 li battery i could find so hopefully it works fine
