One of our star Feathers is the Adafruit HUZZAH32 ESP32 Feather. With the fabulous ESP32 WROOM module on there, it makes quick work of WiFi and Bluetooth projects that take advantage of Espressifs' most popular chipset. Recently, we had to redesign this feather to move from the obsolete CP2104 to the available CH9102F. One thing led to another, and before we knew it, we made a completely refreshed design: the Adafruit ESP32 Feather V2.

This version of the product has pin headers pre-soldered so you can use it instantly, but you cannot solder in stacking headers, for example.

The V2 is a significant redesign, enough so we consider it a completely new product. It still features the ESP32 chip but has many upgrades and improvements:

Compared to the original Feather with 4 MB Flash and no PSRAM, the V2 has 8 MB Flash and 2 MB PSRAM
Additional user button tactile switch on input pin 38
Additional NeoPixel mini RGB LED with controllable power pin
Additional STEMMA QT port for plug-and-play I2C connections
USB Type C port instead of Micro B
Separate controllable 3.3V power supply for STEMMA QT to allow for ultra-low power consumption even with sensors attached
Designed for low power usage: verified with a PPK to draw 70uA from the Lipoly battery in deep sleep and 1.2mA in light sleep.
ESP32 Pico module is much smaller, allowing for clear marking of all breakout pads and additional mounting holes!
Upgrade the USB to serial converter from CP2102 to CH9102F which is available for purchase! The CH9102F has no issues uploading at 921600 bps for speedy firmware loading.

That module nestled at the end of this Feather contains a dual-core ESP32 chip, 8 MB of SPI Flash, 2 MB of PSRAM, a tuned PCB antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support, which means it's perfect for just about any wireless or Internet-connected project.

Features:

ESP32 Dual core 240MHz Xtensa® processor - the classic dual-core ESP32 you know and love!
Mini module has FCC/CE certification and comes with 8 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers
Power options - USB type C or Lipoly battery
Built-in battery charging when powered over USB-C
LiPoly battery monitor with two 200K resistor dividers
Reset and User (I38) buttons to reset the board and as a separate input
High-speed upload with auto-reset and serial debug with ultra-reliable CP2102N chipset.
STEMMA QT connector for I2C devices, with switchable power, so you can go into low power mode.
Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
Low Power friendly! In deep sleep mode, we can get down to 80~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C power for the lowest quiescent current draw.
Works with Arduino or MicroPython

Comes fully assembled and tested with a USB interface that lets you quickly use it with the Arduino IDE or the low-level ESP32 IDF.

This version of the board has also been pre-soldered, so you can plug it right into a solderless breadboard. Click here for the un-soldered version. Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)
