RAKwireless RAK11200 Voice Processing

RAK11200 is a WisBlock Core module for RAK WisBlock based on Espressif ESP32-WROVER. It is a powerful, generic WiFi-BLE MCU module that targets a wide variety of applications. There are two CPU cores that can be individually controlled and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The low-power deep-sleep current consumption of the ESP32-WROVER is about 10 uA. This makes the RAK11200 an ultra-low-power communication solution. RAK11200 can be comfortably programmed with the Arduino™ IDE or PlatformIO.
