This sensor is a high-performance, low-power, digital-output omnidirectional microphone with a bottom port. It is fully compatible with INMP441.
It consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I2S interface. The I2S interface allows it to connect directly to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system. Featuring a high signal-to-noise ratio, it is an excellent choice for near-field applications. With a flat broadband frequency response, it results in natural sounding high clarity.
Features:
Digital I2S interface with 24-bit accurate data
High SNR of 61 dBA
High sensitivity of -26 dBFS
Consistent frequency response from 60 Hz to 15 kHz
Low power consumption: low current draw of 1.4 mA
High PSR: -72 dBFS
Interface Definition:
SCK: Serial data clock for the I2S interface
WS: Serial data word select for the I2S interface
L/R: Left/Right channel selection:
When set to low, the microphone outputs its signal on the left channel of the I2S frame.
When set to high, the microphone outputs its signal on the right channel.
SD: Serial data output for the I2S interface
VCC: Input power supply, ranging from 1.6V to 3.6V
GND: Power ground
Connection to ESP32 Development Board:
Module -- ESP32 Development Board
SCK -- GPIO14
SD -- GPIO32
WS -- GPIO15
L/R -- GND
GND -- GND
VDD -- VDD3.3
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
