ESP32-S3 PowerFeather is a low-power, solar-capable, Li-Ion/LiPo-powered ESP32 development board in a Feather-compatible format. It is perfect for building portable/mobile devices requiring battery power, or devices deployed in remote areas relying on a combination of battery power and off-grid power sources such as solar panels.

This features a Texas Instruments BQ25628E charger IC, and an on-board Onsemi LC709204F fuel guage.

Here are a few reasons why you should use ESP32-S3 PowerFeather for your next project:

Powerful Brains & Connectivity: The board features an Espressif ESP32-S3 module at its core. This module has a speedy dual core processor, tons of flash and RAM, a rich set of peripherals and built-in 2.4 GHz Wi-Fi + Bluetooth LE.
Low Power: The board’s circuitry has been thoughtfully designed and components carefully chosen to minimize quiescent current. As a result, current consumption when the ESP32-S3 is in deep-sleep can be as low as or under 20 µA.
Flexible Power Management & Monitoring: The board has a firmware-controllable charger IC, a battery fuel gauge and other hardware/circuitry to give users utmost flexibility in power management and monitoring. The application firmware can enable or disable charging on-demand, set maximum battery charging current, get an estimate of the battery’s charge and health, turn off a 3.3 V output rail, and much more!
Direct Solar Connection: The board accepts an external DC source up to 18 V, which can either be your typical wall wart adapter or a solar panel. If using a solar panel, the maximum power point (MPP) voltage can be set to extract power at near-MPPT effectiveness.
Extensive Hardware & Software Support: There is an accompanying Arduino and ESP-IDF SDK to give users easy access to the board’s power management and monitoring features. On the hardware side, the board is compatible with hundreds of existing FeatherWing and STEMMA QT modules for faster prototyping.
