ESP32 Forum

I've got an application all developed and ready to go using the ESP3-S3-BOX-LITE devkit - with power from the USB.

Now I need to find a way to power the board using a rechargeable battery - preferably with onboard recharge capability.

We may be looking at repackaging the basic board, battery etc into a new mounting or box - but first, we need some help with the power.

Is there anyone who could help with advice - or maybe would be interested in helping to get our final product produced for a fee?

What are the requirement, how long should it run on the battery ? does it use wifi ? Bluetooth ? Do you know how many milli Amp it require ?

We are using BLE and the display - nothing else. Don't need the buttons, the wifi, or voice. The program is just receiving commands from an App and displaying various graphics. Ideally would like the power on for 8 - 10 hours per day if possible between charge.

Bluetooth use less power than WiFi, so it should be possible. If you measure the current used, you can calculate the required for the batteries. Suggest you try to run it with a power bank and see how long time it will run. Just make sure the power bank dont shutdown when low current is required.

Thanks for the suggestion.

I have tried using batteries - but unsure where to connect. The Datasheet shows that the connectors have a number of 3v, 5v and Grnd connections - but I've tried various combinations and don't seem to get it to work.

I'm a software guy - not an engineer - so any help appreciated on how to connect.

I dont have any ESP3-S3-BOX-LITE so cant tell.
