Product description: Feather ESP32-S2 - WiFi module, GPIO - compatible with Arduino - Adafruit 5000
WiFi module based on the ESP32-S2 chip, featuring 4 MB Flash memory and 2 MB PSRAM. The Feather ESP32 is a low-power 2.4 GHz Wi-Fi System-on-Chip (SoC) solution with a built-in native USB port. The single-core 240 MHz chip does not support Bluetooth connectivity. The product is used in Internet of Things (IoT), smart clothing and home automation projects.
A tutorial on programming the module in the Arduino IDE and CircuitPython can be found at Adafruit.

What is Feather ESP32-S2
Feather ESP32-S2 is a small module with Espressif WiFi microcontroller with low power requirements. Thanks to its small size it can be successfully used in IoT and home automation projects. The Feather ESP32-S2 is based on a single core 240 MHz Tensilica processor. It has 4 MB flash + 2 MB PSRAM. It supports Time of flight (ToF) measurement, among other things. The product is equipped with native USB.
Pinout description
- USB C port: used to power and program the board. When using a Li-Pol battery, it charges the pack when connected to power
- JST 2-PH connector with Li-Pol battery charger: you can connect Li-Pol 3.7 / 4.2 V with 250 mAh to it
- CHG LED: The yellow LED will be on while charging the battery. When charging is complete, the LED goes out. If the battery is not connected, the LED may blink 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: 3.3 V voltage regulator pin
- 3.3 V: output from 3.3 V regulator (peak 500 mA).
For a detailed pin and pin layout, please refer to the manufacturer's website.
