Thesis prototyping platform

Custom ESP32-S3 dev board with camera, IMU, and audio for student research builds — schematic review to assembly.

The problem

A research build needed camera, motion, and audio sensing on one compact, battery-powered ESP32-S3 board — with a layout that would power up first try.

What we did

Schematic design around ESP32-S3 with OV2640 camera, IMU, and I2S microphone
Power-path and battery charging, USB-C with proper CC and ESD protection
Boot/strapping pin review and decoupling pass before layout
PCB layout, prototype assembly, and bring-up

Stack

ESP32-S3KiCadOV2640I2C / I2SLi-ion power-path

Outcome

A working all-in-one board the researcher could build on, avoiding the common first-board failures that cost weeks near a deadline.
