PCB Design
Sensor Interfacing Board
ESP32-based multi-sensor acquisition board with high-fidelity analog signal conditioning.
The Challenge
Eliminating 50Hz mains noise and cross-talk between high-gain sensor channels.
Our Solution
Designed a split-ground plane architecture with isolated analog sections and 24-bit ADCs.
Key Outcomes
- 120dB CMRR across all channels
- Integrated digital filtering
- Plug-and-play support for 5+ sensor types
