NODE Audio Dev Module (WM8978, DHT12)

The NODE Audio Dev Module is a powerful and smart node designed for IoT applications. Paired with the M5Stack Core, it can be programmed to function like an intelligent speaker such as Amazon Echo. This module offers abundant hardware resources, including a built - in high - fidelity audio codec chip, MIC, DHT12, and an IR emitter. The ESP32 provides the ESP - ADF audio development platform, which comprehensively supports audio application development for the ESP32 chip. With ESP - ADF, you can effortlessly add features and develop a wide range of audio applications. It supports various audio formats like MP3, AAC, FLAC, etc., and can play music from multiple sources such as HTTP, HLS, and SPIFFS. It also integrates media services like DLNA and Internet Radio, and supports voice recognition with services like Alexa and DuerOS. Product features include 12 RGBs, a temperature & humidity sensor (DHT12) for status display and environment perception, 4 IR transmitter LEDs and 1 IR receiver, 2 MICs, a HiFi stereo codec chip (up to 24bit DAC), and a 500mAh lithium battery. The kit includes a Node Module, a wall holder, 4 screws, and 4 Type - C USB cables. It can be used in applications such as intelligent IoT nodes, web radios, and intelligent sound boxes. There is also a datasheet available for the WM8978.

Using the NODE Audio Dev Module is easy. First, pair it with the M5Stack Core. Then, use the ESP - ADF platform to program it for different audio applications. You can play music from various sources and support different audio formats. For the temperature and humidity sensor, it will automatically display the status and sense the surrounding environment. When using the IR transmitter and receiver, make sure there are no obstacles in the way. For maintenance, keep the module in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If you want to update the software, follow the official guidelines provided for the ESP - ADF platform. When installing the wall holder, use the provided screws carefully. Also, don't forget to charge the 500mAh lithium battery regularly to keep the module working properly.
