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 CP2102N and one thing led to another and before you know it we made a completely refreshed design which we have further tweaked to create the Adafruit ESP32 Feather V2 with w.FL Antenna.
This feather is exactly like our Feather ESP32 V2 but instead of a PCB trace antenna, there's a w.FL connector for attaching an external RF adapter or antenna. Perfect for use in enclosures or when you want a boost in gain from a bigger dipole. Warning! The antenna connection is an MHF3 / IPEX3 / w.FL is not a common u.FL connector. Check out the WiFi Antenna with w.FL / MHF3 / IPEX3 Connector we carry or the RP-SMA to w.FL / MHF3 / IPEX3 Adapter if you already have an RP-SMA antenna.
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 powe
However, in order to add the PSRAM, and use the new Pico module which was small enough to allow all the fun extras, some of the breakout pads have changed, so here's what you need to know: The pin numbers for the I2C port (SDA, SCL), hardware UART (RX, TX), and SPI (SCK, MOSI, MISO) have changed. If your code has hardcoded use for those pins, you'll want to replace them either by the new numbers or change the code to use the 'pretty' names like SDA or SCK. When selecting the new Feather ESP32 V
That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 8 MB of SPI Flash, 2 MB of PSRAM, tuned '50 ohm' w.FL antenna connector, and all the passives 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 eco-system, you can take advantage of the 50+ Wings that we've designed to add all sorts
