Overview

The ICS-43434 is a high-performance I2S digital MEMS microphone featuring low noise, wide dynamic range, and a built-in low-pass filter. It directly outputs digital audio via the I2S interface, eliminating the need for analog circuitry and reducing noise interference. Suitable for use with ESP32, RP2040, STM32, and Raspberry Pi, this microphone is ideal for audio recording, sound detection, and voice recognition in IoT or embedded projects.

Introduction

โมดูล ICS-43434 I2S MEMS Microphone เป็นไมโครโฟนดิจิทัลขนาดเล็กแบบ I2S Interface ไม่ต้องใช้วงจรแปลงสัญญาณ Analog อีกต่อไป ตัวไมค์มี Low-pass Filter ในตัว ช่วยตัดความถี่สูงเกิน 24kHz ทำให้เสียงคมชัดและลดสัญญาณรบกวน รองรับการเชื่อมต่อกับ ESP32, RP2040, STM32, Raspberry Pi และบอร์ด MCU ที่มี I2S Interface เหมาะสำหรับโปรเจกต์ Voice Recognition, Sound Detection, Audio Recording และระบบ IoT ที่ต้องการบันทึกเสียงคุณภาพสูงในขนาดกะทัดรัด

Features

  • ใช้ I2S Digital Interface ไม่ต้องใช้ ADC หรือวงจร Analog
  • Built-in Low-pass Filter ตัดความถี่เกิน 24kHz
  • รองรับ Sampling Rate สูงถึง 51.6 kHz
  • ขนาดเล็กแบบ SMD เหมาะสำหรับติดตั้งใน IoT Device
  • เลือกช่อง Left/Right ได้โดยการต่อ Select Pin (GND/VDD)
  • รองรับแรงดันใช้งาน 1.6–3.6V เหมาะกับระบบ Logic 3.3V
  • เสียงชัดเจน SNR สูงถึง 65 dBA / AOP 120 dB SPL

Specification

  • Interface: I2S Digital Output
  • Operating Voltage: 1.6V – 3.6V
  • Frequency Response: 50 Hz – 15 kHz
  • Sensitivity: -26 dBFS ±1 dB
  • Signal-to-Noise Ratio (SNR): 65 dBA (High Performance Mode)
  • Current Consumption: 490 μA (High Performance) / 230 μA (Low Power)
  • Acoustic Overload Point (AOP): 120 dB SPL
  • Sampling Rate: 23 – 51.6 kHz (High Performance) / 6.25 – 18.75 kHz (Low Power)
  • Port Type: Bottom Port
  • Size: Compact MEMS package, suitable for breakout module

Caution

โมดูลนี้ไม่รองรับแรงดัน 5V ห้ามต่อเข้าระบบ 5V Logic โดยตรง ต้องใช้กับบอร์ดที่มี Interface I2S เท่านั้น เช่น ESP32, RP2040, STM32, Raspberry Pi หากต้องการเสียงสเตอริโอ ต้องใช้ไมโครโฟนสองตัวและตั้งค่า Select Pin แยก Left/Right

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
