Introduction

ESP-WROOM-32 is a wild used Wi-Fi-BT-BLE MCU module, so, as you can see, this module combines Wi-Fi and Bluetooth on a board, and it don’t need a extra controller for it has a build-in MCU, it’s so powerful that it can be apply in various application such as low-power sensor networks, voice coding, MP3 decoding and so on. Our product of ESP8266 may amazing you about it the combine of Wi-Fi and MCU on an little board, this ESP-WROOM-32 will do more than what ESP8266 does, and the ESP-WROOM-32 is more tiny than the ESP8266, by the way, for the ESP-WROOM-32 is a module, it’s tiny, you may need to solder it on a board with support circuit()
