{"product_id":"max98357-i2s-amplifier-module","title":"MAX98357 I2S Amplifier Module","description":"\u003cp\u003eThis I2S digital amplifier based on the MAX98357 I2S Class D amplifier module works great with microcontrollers with I2S audio outputs like ESP32 and can be applied to projects like IoT nodes, smart home devices, Bluetooth audio players, and so on.\u003c\/p\u003e\n\u003cp\u003eThe module supports a 3.3V-5V power supply. And it can output over 2.5W of power when driven by 5V and a 4Ω speaker. Besides, it allows users to set different modes (off, left channel, right channel, and mixed) by changing the resistance on the SD port. The product defaults to mixed mode.\u003c\/p\u003e\n\u003cp\u003eFeaturing a small size, this I2S amplifier comes with stamp holes that enable it to be directly plugged into or mounted on a PCB and breadboard. Also, it is designed with PH2.0 and stamp holes for connecting speakers, flexible, and convenient to use.\u003c\/p\u003e\n\u003ch2\u003eFEATURES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMAX98357 I2S digital Class D amplifier, power \u0026gt;2.5W\u003c\/li\u003e\n\u003cli\u003e3.3V~5V voltage power supply\u003c\/li\u003e\n\u003cli\u003eSwitchable sound channel\u003c\/li\u003e\n\u003cli\u003eAdjustable gain\u003c\/li\u003e\n\u003cli\u003eStamp holes design, support SMT and DIP\u003c\/li\u003e\n\u003cli\u003eTwo ways to connect a speaker: PH2.0 and stamp holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAPPLICATIONS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBluetooth Audio Player\u003c\/li\u003e\n\u003cli\u003eIoT Node Audio Player\u003c\/li\u003e\n\u003cli\u003eSmart Home Voice Interaction\u003c\/li\u003e\n\u003cli\u003eRobotic Device Audio Player\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSPECIFICATION\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModule Parameters\u003c\/li\u003e\n\u003cli\u003eMCU: MAX98357A\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: DC 3.3V~5V\u003c\/li\u003e\n\u003cli\u003eOutput Power: 8Ω 1.8W \/ 4Ω 2.5W (at 12db)\u003c\/li\u003e\n\u003cli\u003eOutput Channel: single channel\u003c\/li\u003e\n\u003cli\u003eCommunication Interface: I2S interface\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40℃ - ＋80℃\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -40℃ - ＋80℃\u003c\/li\u003e\n\u003cli\u003eDimension (Without Packaging): 18mm × 18mm\/ 0.059 × 0.059\u003c\/li\u003e\n\u003cli\u003eChip Audio-relevant Parameters\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e(VDD = 5V, VGND = 0V, GAIN_SLOT = VDD.
