Hello all,
I want to introduce ESP32-S3 PowerFeather, a dev board that should make it a little easier to create solar + Li-ion/LiPo powered projects! It uses a charger IC that's smarter than most other similar boards: Texas Instruments BQ25628E; and also has an on-board LC709204F fuel gauge. Deep-sleep current can be under 20 uA. It has an Arduino/ESP-IDF SDK to help manage the use of the charger and fuel gauge, as well as other features. More details and link to documentation can be found on: https://powerfeather.dev/.
Cheers,
powerfeatherdev

Since the release of ESP32-S3 PowerFeather I’ve been working on a demo web app that lets users explore some of the features of ESP32-S3 PowerFeather, which I recently got to a decent state:
![Image](https://i.ibb.co/WWMsGxT/charging-current.jpg)
The web app is served from the ESP32-S3 PowerFeather (acting as an AP) and is accessed from the tablet's web browser. The part encircled in yellow shows the battery being charged at 1.5 A from the solar panel at the set MPP voltage of around 12 V.
The web app also displays other supply & battery telemetry information as well as some power management controls which are all built-in into the board and accessed using the PowerFeather-SDK API.
For those interested in the demo web app, maybe to try it on their PowerFeather or just to see how this was created: https://github.com/PowerFeather/powerfeather-demo.

I made a showcase video for the ESP32-S3 PowerFeather: https://youtu.be/VF9AFk1Hf88
