Using external battery on Spresense

Larry

Hi All,

I have a question regarding using the external battery on Spresence. If I connect the board with a TFT screen and network module, is it still possible to run the code by using the battery?

The only document right now I referred to is the section 1.16 of the following document: https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_powering_the_main_board_with_external_power
I have no idea about the detailed hardware connection and the type of battery. Any suggestions / recommendations here?

Thank you in advance for any help.

Best,

Larry

Hi, @Larry
Yes, you are still able to power Spresense with a battery.

Here are some other useful links that talk about powering Spresense externally and what kind of battery to use.
