Hw-044 Datasheet _verified_ Here

When reading the hw-044 datasheet , you must respect the operating limits of the MAX98357 chip. Exceeding these values can destroy the module.

The Raspberry Pi’s GPIO pins are digital only. To read analog values from the HW-044, you must add an external ADC, such as the MCP3008 (8-channel, 10-bit) or ADS1115 (16-bit). hw-044 datasheet

: Sometimes, datasheets include application notes or examples of how the component can be used in a circuit, along with recommended external components. When reading the hw-044 datasheet , you must
