With the HUZZAH32 Breakout Adafruit, your next ESP32 project will be in a pure state. This card is basically the'big sister' of our HUZZAH 8266, but instead of an ESP8266 it has the'32'! We have reduced our popular Feather ESP32 by removing the battery charger and USB-serial converter. You only have one controller, protective diodes, two buttons and one LED. For some projects, where the price and size are higher, you can program this card via the FTDI cable if necessary, and then let it run.

Note that this card is not supplied with a USB-to-serial converter chip and an automatic reset circuit. Instead, you will need to connect a CP2104 Friend or FTDI cable. Then, before downloading the code, put it in bootloader mode by holding down the GPIO #0 button and clicking on the Reset button, then releasing the #0 button.

This module contains a dual-core ESP32 chip, 4 MB of SPI Flash, a tuned antenna that you need to take advantage of this powerful new processor. The ESP32 supports WiFi and Bluetooth Classic/LE. This means it is perfect for just about any wireless or Internet-connected project.

The ESP32 is a perfect update of the ESP8266 that has been so popular. In comparison, the ESP32 has many more GPIOs, many more analog inputs, two analog outputs, several additional devices (such as a spare UART), two cores so you don't have to give up to the WiFi manager, much faster processor, etc.

Delivered fully assembled and tested, pre-programmed with the ESP32 SPI WiFi coprocessor firmware that you can use in CircuitPython to use in a WiFi coprocessor on SPI + 2 pins. We also add a connector so you can solder it and connect it to a solderless breadboard.
