This is a development board comes with both Wifi and Bluetooth. The core of this module is the ESP32-D0WDQ6 chip which is extensible and adaptive. Two CPU cores can be individually controlled or powered up The user can power off the CPU and use a low-power coprocessor to continuously monitor the status changes of the peripherals or whether certain analogs exceed the threshold.
Powerful and versatile it can be used in low-power sensor networks and high demanding tasks such as voice coding audio streaming and MP3 decoding.
