Welcome to your new project. Imagine what you can build here.

An 8-bit audio recorder for use with a Raspberry Pi. The point of this circuit is to learn how to use an ADC, which is why it connects to the GPIO.

70x50 mm CNC-friendly raw-laminate XIAO ESP32S3 lapel audio recorder prototype with socketed XIAO, dual external INMP441 microphones, LiPo connector, button/status LED, and SD-card recording support. Layout prioritizes hand soldering, replaceable parts, wide traces, and generous isolation clearances over compactness.

ISD1740SY-based voice record/playback circuit with pushbutton controls, LED status indicator, microphone/speaker connections, oscillator/AGC network, and 5V power decoupling.

Compact wearable necklace PCB for 5-second audio capture. A button press starts recording with an audible beep, and button release/end of the 5-second window produces a second beep. The design targets low-power LiPo operation, safe charging, small necklace-friendly form factor, accessible programming/debug, and production-ready ERC/DRC-clean PCB layout.
