ESP32-S3-DevKitC-1 MMG Mapping

This is the pcb design for collecting signals from 10 piezo sensors. The signals are being amplifie and filtered and sent to the analogue pin of esp32. The esp32 schematic was selected from original espressif esp32-s3 devkit c1 design.

Project Summary:

• ESP32 module
• battery charger
• USB to UART (default)
• signal conditioning circuit for 10 sensors
• push button for labelling sensors
