This is Adafruit ESP32 Feather V2 – 8MB Flash + 2 MB PSRAM – STEMMA QT.

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 and one thing led to another before you know it we made a completely refreshed design: the Adafruit ESP32 Feather V2.

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 the 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 are 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 the serial converter from CP2102 to CH9102F which is available for purchase! The CH9102F has no issues with uploading at 921600 bps for speedy firmware loading.

Features:

  1. ESP32 Dual core 240MHz Xtensa® processor – the classic dual-core ESP32 you know and love!
  2. The mini-module has FCC/CE certification and comes with 8 MByte of Flash and 2 MByte of PSRAM – you can have huge data buffers
  3. Power options – USB type C or Lipoly battery
  4. Built-in battery charging when powered over USB-C
  5. LiPoly battery monitor with two 200K resistor divider
  6. Reset and User (I38) buttons to reset board and as a separate input
  7. High speed upload with auto-reset and serial debug with ultra-reliable CP2102N chipset.
  8. STEMMA QT connector for I2C devices, with switchable power, so you can go into low power mode.
  9. Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
  10. 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.
  11. Works with Arduino or MicroPython
  12. Ultra-low noise analog amplifier
  13. Hall sensor
  14. 10x capacitive touch interface
  15. 32 kHz crystal oscillator
  16. 3 x UARTs (only two are configured by default in the Feather Arduino IDE support, one UART is used for bootloading/debug)
  17. 3 x SPI (only one is configured by default in the Feather Arduino IDE support)
  18. 2 x I2C (only one is configured by default in the Feather Arduino IDE support)
  19. 12 x ADC input channels
  20. 2 x I2S Audio
  21. 2 x DAC
  22. PWM/timer input/output available on every GPIO pin
  23. On-board PCB antenna
  24. SDIO controller or peripheral 50 MHz
