3.3V PCB Mic Board ICS 43434 with Compact Small Footprint for Space Saving Input Device Prototype Assembly Mounting Use Tasks

Compact PCB Structure: A 1.65cm / 0.64inch by 1.23cm / 0.48inch board with 0.16cm / 0.06inch thickness fits tight layouts, while mounting holes and through-hole pads organized integration inside small devices Built For Project Integration: The module format suits voice projects, sound detection builds, home concepts, development board experiments, and maker prototypes that need a small input component Single Module Package: Includes a single omnidirectional microphone module for direct board mounting, giving developers a focused part for testing, replacement planning, or compact electronics assembly workflows Clear 3.3V Reference: The board marking shows 3.3V guidance directly on the module, giving builders a practical reference point when planning controller-side wiring, pad mapping, and early prototype bring-up tasks Omnidirectional Pickup: This module uses an omnidirectional microphone layout to receive surrounding voice and sound input from multiple directions, making it useful for embedded electronics that need stable collection during development work
