DF Robot MAX98357A I2S Amp Module
The DF Robot MAX98357A I2S Amp Module is an excellent choice for microcontrollers with I2S audio outputs like ESP32. Ideal for IoT nodes, smart home devices, and Bluetooth audio players, it supports a 3.3V-5V power supply and delivers over 2.5W of power to a 4Ω speaker at 5V. Users can easily switch between different modes (off, left channel, right channel, and mixed) by changing the resistance on the SD port. Its small size allow easy integration on PCBs and breadboards, while the PH2.0 enables seamless speaker connections.

Wiring Diagram
Pinout
- SPK - Speaker output - negative
- VCC - Supply voltage 3.3 ~ 5V
- GND - Ground
- NC - Pin is not connected
- SD - Disabling and selecting the output channel (off, left, right or stereo - left and right)
- GAIN - Gain Control - 9 dB by default
- SPK+ - Speaker output - positive
- DIN - Data in - data input
- BLCK - Bit Clock - informs the amplifier when to read data from the data pin
- LRC - Frame Clock - informs the amplifier about the input channel (left / right or stereo)
- GND - Ground
- VCC - Supply voltage 3.3 ~ 5V
Gain Control
- Gain is 15dB when there is a 100K resistor connected between GAIN and GND
- Gain is 12dB when GAIN is directly connected to GND
- Gain is 9dB(Default status) when nothing is connected to GAIN
- Gain is 6dB when GAIN is directly connected to VCC
- Gain is 3dB when there is a 100k resistor connected between Gain and VCC
