Description
The RAK18060 is a 5.6W stereo amplifier module based on the Texas Instruments TAS2560 which extends the WisBlock system with sound generating capability.
The RAK18060 is a module that converts I2S digital audio to analog signals to drive a speaker. It supports left and right I2S audio channels and control over I2C.
The RAK18060 can be used in applications such as music players, audible alarms and really any device that needs speakers!
