- Digital MEMS Microphone Breakout Board (SPH0641LU4H-1)
- Captures sound from 100Hz to 80kHz, ideal for ultrasonic applications
- Features exclusive DFSDM module for easy PDM input processing
- Compatible with the STM32L476RGT6 model
The Digital MEMS Microphone Breakout Board (SPH0641LU4H-1) is a sophisticated piece of technology that features a digital MEMS microphone, specifically the SPH0641LU4H-1 model from Knowles. The board is designed with a pin spacing of 2.54mm. This device is capable of capturing sound ranging from audible to ultrasonic waves, specifically between 100Hz to 80kHz, with a high degree of sensitivity. This makes it suitable for applications in ultrasonic sensors and ultrasonic communication.
The board is equipped with the DFSDM module (Digital Filter for Sigma-Delta Modulators), a feature that is exclusive to the STM32L4 series from STMicroelectronics. This module facilitates the easy reception and processing of the PDM input of a digital microphone, similar to AD conversion. The board is compatible with the STM32L476RGT6 model, providing a practical example of its usage.
