What is Feather ESP32-S3

Feather ESP32-S3 is a small module equipped with an Espressif microcontroller that supports WiFi and Bluetooth communication with low energy consumption . Thanks to its small size, it can be successfully used in projects in the field of, among others IoT and home automation. Feather ESP32-S3 is based on a dual -core Tensilica 240 MHz processor . It has 8 MB of Flash, but does not come with PSRAM. It supports i.a. Time of flight (ToF) measurement. The product is equipped with native USB.

Pinout description

  • Native USB C port : used for powering and programming the board. It allows you to charge a Li-Pol battery plugged into the JST connector.
  • JST 2-PH connector connected to the Li-Pol battery charger system: Li-Pol 3.7 / 4.2 V with a capacity of 250 mAh or more can be connected to it.
  • CHG LED: The LED lights while the battery is charging. When charging is complete, the LED turns off. If the packet is not connected, the LED may flash quickly.
  • GND: common ground for all power and logic circuits.
  • BAT: positive voltage from / to 2-pin JST socket for optional Li-Pol battery.
  • USB: positive voltage from / to USB C socket if USB is connected.
  • EN: 3.3V voltage regulator pin.
  • 3.3 V: regulator output 3.3 V (instantaneous current 500 mA).
The pins of the module Leads of the Feather ESP32-S3 module.
Feather ESP32-S3 The board is equipped with the ESP32-S3 system.
