ESP32-S3 Audio Hardware Optimization

Angebotsbeschreibung

I am looking for an expert Electronics Design Engineer to review, optimize, and finalize a draft KiCad schematic for a custom, battery-powered audio logging device. The core architecture relies on an ESP32-S3-WROOM-1-N16R8-1U module paired with a TDK T5838 digital microphone featuring Acoustic Activity Detection (AAD). The device operates primarily in an ultra-low power standby mode: the ESP32-S3 stays in deep sleep with Wi-Fi completely turned off, while the TDK T5838 remains always-on to monitor the acoustic environment. When a sound trigger occurs, the microphone must wake the ESP32-S3 using an AAD interrupt (via D1, D2, or Analog AAD mode) to record audio onto a microSD card. The ESP32-S3 will wake up its Wi-Fi radio only during a specific, firmware-defined time window to transmit the ...
