Microphone Testing Kits Expand Design Options

Microphone development kits provide engineers a way to test analog and digital MEMS and ECM designs for audio products and microphone arrays.

Same Sky has introduced seven microphone development kits aimed at making it easier for engineers to evaluate and test different microphone technologies during product development.

The new kits package four standalone microphone evaluation circuits into each set, with plated through-hole I/O terminals that allow for faster setup and easier integration into test environments. The goal is to reduce the effort involved in comparing microphone types and configurations across different applications.

The lineup covers both microelectromechanical systems (MEMS) and electret condenser microphone (ECM) technologies, spanning analog and digital MEMS options as well as unidirectional, omnidirectional, and noise-canceling ECM designs. Each kit uses detachable evaluation boards, allowing engineers to swap and test microphones without redesigning supporting circuitry.

The new product range includes:

• DEVKIT-ECM-001: One noise-canceling ECM, one unidirectional ECM for targeted sound capture, and two omnidirectional ECMs
• DEVKIT-MEMS-001: Two analog-output and two digital-output MEMS microphones with top-port and bottom-port acoustic entry
• DEVKIT-MEMS-002: Four digital-output MEMS microphones with top-port sound entry
• DEVKIT-MEMS-003: Four analog-output MEMS microphones in both top-port and bottom-port configurations
• DEVKIT-MEMS-004: Four analog-output MEMS microphones with mixed top-port and bottom-port options
• DEVKIT-MEMS-005: Four analog-output MEMS microphones with top-port and bottom-port variants
• DEVKIT-MEMS-006: Two analog-output and two digital-output MEMS microphones, including matched digital MEMS units for microphone array testing

To support design and evaluation, Same Sky is also pointing engineers to its Resource Library, which includes technical articles, videos, and other product development materials focused on microphone integration and audio system design.
