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. One thing led to another, and before we knew it, we made a completely refreshed design: the Adafruit ESP32 Feather V2.\u003c\/p\u003e \u003cp\u003eThis version of the product has pin headers pre-soldered so you can use it instantly, but you cannot \u003ca href=\"\/ru\/products\/stacking-headers-for-feather-12-pin-and-16-pin-female-headers\"\u003esolder in stacking headers\u003c\/a\u003e, for example.\u003c\/p\u003e \u003cp\u003eThe V2 is a significant redesign, enough so we consider it a completely new product.

The ESP32 has both WiFi and Bluetooth Classic\/LE support, which means it's perfect for just about any wireless or Internet-connected project.\u003c\/p\u003e \u003cp\u003eBecause it's part of our \u003ca href=\"\/ru\/collections\/adafruit-feather\"\u003eFeather eco-system\u003c\/a\u003e, you can take advantage of the Wings we've designed to add all sorts of cool accessories.
