Adafruit ESP32 Feather V2 (aka Huzzah32 Feather V2) is an upgrade to the company’s HUZZAH32 ESP32 Feather, still based on ESP32 WiFi & Bluetooth processor, and designed with the initial goal of replacing the obsolete CP2104 with the CP2012N USB to TLL chip.
But Adafruit ended up doing a complete redesign with extra storage (8MB flash in total), 2MB PSRAM, a USB-C port replacing the Micro USB port, an extra tactile switch, an RGB LED, lower power consumption, and more.
Adafruit ESP32 Feather V2 specifications:
- Wireless module – Espressif Systems ESP32-PICO-Mini-02 (PDF datasheet) with an ESP32 dual-core Xtensa processor @ up to 240MHz with 2.4 GHz WiFi and Bluetooth Classic/LE, 8MB flash, 2MB PSRAM, PCB antenna, FCC/CE certification.
- USB – USB Type-C port for power and programming via CP2102N chipset
- 16-pin and 12-pin GPIO headers with GPIOs, analog inputs, I2C, UART, SPI, DAC, etc…
- STEMMA QT connector for I2C devices, with switchable 3.3V power, so you can go into low power mode.
- Misc – Reset and User (I38) buttons, charge/user LEDs, NeoPixel RGB LED
- Power Supply
- 5V via USB Type-C port
- 2-pin header for 3.7-4.2V LiPo battery
- Built-in battery charging when powered over USB-C
- Power consumption – As low as 70uA in deep sleep mode as measured with Nordic Power Profiler Kit, 1.2mA in light sleep
- Dimensions – 52.3 x 22.8 x 7.2mm (Adafruit Feather form factor)
The extra features are possible thanks to the much more compact ESP32-PICO-Mini-02 (13.2 × 16.6 mm) module replacing the ESP32-WROOM-32 module in the original Huzzah32 ESP32 board. The company did have to switch some pins for I2C, UART, SPI, etc.. so the new board is not 100% firmware compatible, but that’s just a question of changing the pin numbers. Adafruit provides support for Arduino and MicroPython for the board, but somehow CircuitPython is not listed.
Adafruit ESP32 Feather V2 sells for $19.95 plus shipping… when it is in stock, which is not the case at the time of writing.
