Waveshare WM8960 Stereo Codec Audio Module With Mic
Build stereo audio into your project with the Waveshare WM8960 Stereo Codec Audio Module With Mic. This low-power module supports stereo encoding and decoding, sound recording, and direct speaker playback. The integrated MEMS silicon microphone lets you record sound, while the standard 3.5 mm four-segment earphone jack supports recording through external earphones with a microphone. A dual-channel speaker interface can directly drive connected speakers. Flexible audio: Supports common sampling rates from 8 kHz to 48 kHz, including 11.025, 22.05, and 44.1 kHz. Sound effects: Supports stereo and 3D surround effects. Development support: Includes development resources, a manual, and STM32 examples for playback and recording. Use this audio codec module for embedded projects that need recording, playback, and stereo sound processing. Specifications Codec: WM8960 Operating voltage: 3.3 V Control interface: I2C Audio interface: I2S Audio format: WAV Supported sampling rates: 8, 11.025, 22.05, 44.1, and 48 kHz, among others DAC signal-to-noise ratio: 98 dB ADC signal-to-noise ratio: 94 dB Earphone driver: 40 mW, 16 Ω at 3.3 V Speaker driver: 1 W per channel, 8 Ω BTL Package Contents Development resources: Manual and STM32 playback and recording examples Packaging One package weight: 0.02 kg / 0.04 lb One package size: 7 × 4 × 2 cm / 2.76 × 1.57 × 0.79 in Quantity per carton: 1,600 pieces Carton weight: 15.00 kg / 33.07 lb Carton size: 56 × 40 × 40 cm / 22.05 × 15.75 × 15.75 in 20GP loading: 297 cartons × 1,600 pieces = 475,200 pieces 40HQ loading: 690 cartons × 1,600 pieces = 1,104,000 pieces Package Weight One Package Weight 0.02kgs / 0.04lb One Package Size 7cm * 4cm * 2cm / 2.76inch * 1.57inch * 0.79inch Qty per Carton 1600 Carton Weight 15.00kgs / 33.07lb Carton Size 56cm * 40cm * 40cm / 22.05inch * 15.75inch * 15.75inch Loading Container 20GP: 297 cartons * 1600 pcs = 475200 pcs40HQ: 690 cartons * 1600 pcs = 1104000 pcs
