Adafruit has up to date considered one of their hottest Feather type issue boards. The new ESP32 Feather V2 extends the earlier ESP32 Feather by rising the flash reminiscence, including PSRAM, a push-button, a NeoPixel, and extra!
“Lately we needed to redesign this feather to maneuver from the out of date CP2104 to the CP2012N and one factor led to a different and earlier than you recognize it we made a very refreshed design: the Adafruit ESP32 Feather V2.” — Angelica, Adafruit weblog
Adafruit’s Feather boards are a type issue measuring about 23 by 53 millimeters. They function a pinout that places the usual microcontroller options, like analog inputs, in the identical bodily location. Additionally on board is a USB interface, a connector for LiPo batteries, and a battery charging circuit.
The replace checklist between the ESP32 Feather V2 and the unique is surprisingly in depth! One replace is that the USB Micro connector is now a USB Sort-C, which is a development we anticipate to see with Adafruit boards shifting ahead. One other is the addition of a user-readable push-button and a NeoPixel Mini RGB LED. Additionally, a STEMMA QT connector lets you add sensors and different parts with out soldering.

Further room for these new options occurred due to a change to the SoC module. The ESP32-Pico mini-module opened up sufficient room for the brand new options, and the board nonetheless has sufficient remaining house to enhance the readability of the pinout’s silkscreen!
In comparison with the earlier ESP32 Feather, the mini-module on the V2 doubles the flash reminiscence to eight megabytes and provides 2 megabytes of PSRAM. PSRAM is pseudo-static RAM. From the consumer’s perspective, it simply means extra RAM accessible for applications working on the 240 MHz dual-core Xtensa processor! The module’s built-in antenna and radios help WiFi, Bluetooth, and Bluetooth Low Vitality.
Adafruit gave some critical consideration to energy administration on the ESP32 Feather V2. First, the 3v3 rail to the STEMMA QT connector is controllable. Now it’s a lot simpler to show off exterior sensors to avoid wasting energy. Even the mini NeoPixel LED has a controllable energy pin. Second, Adafruit profiled energy utilization with a Nordic Energy Profile Equipment. The sunshine sleep present consumption at just one.2 milliamps and deep sleep all the way down to 70 microamps!
ESP32 pin numbers assignments for the serial protocols have modified. Bodily I2C, SPI, and UART are all in the identical place on the Feather type issue. Nevertheless, in software program, the pins at the moment are totally different. Altering the board/processor kind needs to be sufficient to maintain code compatibility should you’re utilizing consts in your code.

Whereas we expect the updates to the venerable ESP32 Feather are spectacular on their very own, much more so is the worth for the brand new board is identical at $19.95! Be taught extra about Adafruit’s ESP32 Feather V2 on its product web page.
