RAKwireless RAK18061

RAK18061 is a mono amplifier module, part of the WisBlock Audio Series. It is designed based on the TAS2560 from TI, which features an ultra-low-noise audio DAC and Class-D audio amplifier. It incorporates speaker voltage and current sensing feedback for use with speaker protection algorithms. The RAK18061 can drive the speaker to play audio through the input I2S signals. With other WisBlock modules, it can achieve rich applications, such as recording and voice control functions.
