Product information "Adafruit ESP32 Feather V2, 8MB Flash + 2 MB PSRAM"

One of our star Fathers is the Adafruit HUZZAH32 ESP32 Feather - with the fabulous ESP32 WROOM module on it, it makes quick work of WiFi and Bluetooth projects that take advantage of Espressif's most popular chipset. Recently we had to revise the Feather to move from the outdated CP2104 to the CP2012N. One thing led to another and before you know it, we've created a completely redesigned design: the Adafruit ESP32 Feather V2.
The V2 is a significant redesign, 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 tactile user button on input pin 38
Additional NeoPixel mini RGB LED with controllable power pin
Additional STEMMA QT connector for plug and play I2C connections
USB type C connector instead of micro B
Separate controllable 3.3V power supply for STEMMA QT to enable ultra-low power consumption even when sensors are connected
Designed for low power consumption: verified with a PPK to draw 70uA from the Lipoly battery in deep sleep and 1.2mA in light sleep.
The ESP32 Pico module is much smaller, allowing for clear marking of all breakout pads and additional mounting holes!
Upgrading the USB to serial converter from CP2014 (2mbps max rate) to CP2102N which can handle 3 mbps

However, to add the PSRAM and use the new Pico module, which is small enough to allow for all the fun extras, some of the breakout pads have changed, so here is the key information:

The pin numbers for the I2C port (SDA, SCL), hardware UART (RX, TX) and SPI (SCK, MOSI, MISO) have changed. If your code has hard-coded these pins, you will need to either replace them with the new numbers or change the code to use the "pretty" names such as SDA or SCK.
If you select the new Feather ESP32 V2 board in the Espressif Board Support Package, the correct numbers will be substituted.
Note that the names are in the same locations, we have not changed where the I2C/UART/SPI pins are located on the board, only which ESP32 pin numbers they are connected to in the module.
The "corner" pin next to TX has been changed from pin 21 to 37. This pin is not used in any FeatherWings as it is considered an "extra pin". It has also been changed from a GPIO to an input only
The remaining numbered pins and pins A0-A5 have not changed their pin numbers.

The module at the end of the Feather contains a dual-core ESP32 chip, 8MB of SPI flash, 2MB of PSRAM, a tuned PCB antenna and all the passive components you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it's perfect for just about any wireless or internet-connected project.
Because it's part of our Feather ecosystem, you can take advantage of the 50+ wings we've designed to add all kinds of cool accessories. Plus, the integrated battery charging and monitoring you know and love from the ESP32 Feather is also included in this upgrade.
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 Flash and 2 MByte PSRAM - you can have large data buffers
Power supply options - USB type C or Lipoly battery
Built-in battery charging when powered via USB-C
LiPoly battery monitoring with two 200K resistor dividers
Reset and user button (I38) to reset the card 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 supply so you can switch to low power mode.
Charge/user LEDs + status NeoPixel with pin-controlled power supply for low power consumption
Low power friendly! In deep sleep mode, we can reduce the current consumption of the Lipoly connector to 80~100uA. The quiescent current comes from the power regulator, the ESP32 chip and the Lipoly monitor. Switch off the NeoPixel and the external I2C power supply to get the lowest quiescent current.
Works with Arduino or MicroPython

The device comes fully assembled and tested and has a USB interface that allows you to quickly use it with the Arduino IDE or the low-level ESP32 IDF. We have also included some headers so you can solder it in and plug it into a solderless breadboard.

Lipoly battery and USB cable not included

Adafruit: The expert for open source hardware

For more than ten years, programmers and tinkerers have benefited from the expertise of the Adafruit brand. Whether for beginners or proven experts, Adafruit has the right hardware components ready for your next IoT project.

Light comes into the dark with Adafruit NeoPixel

One extremely popular product line from the company's broad portfolio is Adafruit NeoPixel. These nifty LED components come in a wide variety of designs and color temperatures. NeoPixel modules are available, for example, in the form of a practical stick with five intelligent LEDs in red, green and blue (RGB) or in white (W), as a shield with 40 eye-saving RGBW LEDs in which all pixels are individually addressable, and as a jewel with seven RGBW LEDs that can be controlled with 8-bit PWM per channel.

Especially popular is the Adafruit NeoPixel Ring with 16 ultra-bright, intelligent RGB LEDs including integrated drivers, which you only need a single microcontroller to control. The trick is that the Adafruit NeoPixel rings form a chain, so to speak: You couple the output pin of one with the input pin of the other.

With the Adafruit NeoPixel products you can realize a wide variety of projects - there are virtually no limits to your creativity. With the help of an Arduino, a jumper cable and the appropriate software, you can control a NeoPixel ring individually and light up the small LEDs as you wish - either individually or in a specific combination. This way, you can also create your own Vu meter with the versatile LED components. Practical: To make programming Adafruit NeoPixel easier, Adafruit provides an Arduino library as well as a Python library.

Adafruit Feather Boards: Powerful hardware in a compact format

With Adafruit Feather, the hardware specialist from the States also has various powerful development boards in its range, which are essentially equivalent to an Arduino in terms of function. All of these boards are equipped with similar features; among other things, the pin assignment is the same and there are also many parallels when it comes to the microcontrollers and the battery charging properties. In addition, you can also find Feather boards with special devices like Bluetooth, Wi-Fi and cellular network connectivity as well as boards with microSD slot in Adafruit's product range. The name "Feather" is no coincidence: The boards are also characterized by being particularly compact and, above all, lightweight.

The range of top-class product highlights is wide: The STM32F405 Feather, for example, is the fastest CircuitPython board from Adafruit with an outstanding 168 MHz and meets the highest demands. It is equipped with a STEMMA QT / Qwiic port at the end, which makes it easy to connect to I2C sensors. The Adafruit Feather nRF52840 Express, on the other hand, shines with Bluetooth Low Energy and can also be used with CircuitPython thanks to native USB support.

Another important part of Adafruit's portfolio are the FeatherWings. With these expansion modules, you can also include components such as a display or a motor driver in your IoT project. The FeatherWing Proto is a proven classic in Adafruit's portfolio. This is ideally suited as a prototyping add-on for all Feather boards. The Adafruit FeatherWing Wing Tripler Mini Kit, on the other hand, is ideal if you want to connect a Feather to two other FeatherWings at the same time.

With the Adafruit MIDI FeatherWing Kit you get a music capable FeatherWing, thanks to which you can equip your Feather with MIDI input and output jacks. And with the Adafruit FeatherWing OLED you can easily add a small OLED display to your Feather board - no soldering required.

Adafruit: What's behind the brand

As an expert in open-source hardware, Adafruit has long since established itself in the electronics industry. The company was founded in 2005 by Limor Fried. At the time, the talented and innovative electrical engineer was still a student at the renowned Massachusetts Institute of Technology (MIT). To this day, Fried is CEO of the electronics giant, which is now headquartered in New York. The company's name also goes back to its founder: Fried was once known on the World Wide Web by the nickname "Ladyada" - a tribute to the famous IT pioneer Ada Lovelace.

Adafruit says it is committed to getting more people excited about technology and science - and thanks to its first-class products, the hardware expert from the USA is sure to succeed!
