The ESP8266 started a small revolution by bringing WiFi to a small and cheap package that also had enough processing power and enough pins to get small things done. Now get ready to take your bite-sized WiFi capabilities to the next level with the ESP32 Development Board!

Firmware tips:

1. Connect the micro USB directly from the computer to the board. Do not use a hub in the middle. Use a short cable.
2. Install the ESP32 Arduino IDE addon (see video below).
3. Select ESP-32 Dev Module in the Arduino IDE.
4. Put the ESP32 into boot mode by holding down the BOOT button and pressing and releasing the EN button (reset).
5. Select the serial port (if the serial port does no appear, ensure that the CP2102 drivers are correctly installed). 
6. Start the download process.  When the download starts, press and release the BOOT button again. The download process should now start.
7. The community at http://esp32.net/  has the best support and information regarding the ESP32.
