ESP32 Hardware & Firmware Design Review

Description

ESP32 Hardware + Firmware Design Review

(High-Trust, Pre-Production Audit)

Before committing to manufacturing, field testing, or customer demos, it’s critical to validate that your ESP32 hardware and firmware architecture are production-ready.

The ESP32 Hardware + Firmware Design Review is a time-boxed expert audit designed to catch common (and costly) design mistakes early—without rewriting your code or redesigning your board.

This service is ideal as a confidence-building first engagement before deeper development work.

• Teams building ESP32-based custom PCBs

• Founders preparing for manufacturing or pilot runs

• Engineers who want an independent expert review

• Projects showing instability, power issues, or flaky sensors

 Scope

This is a structured review, not open-ended consulting.

Hardware Review

• ESP32 pin mapping & peripheral usage validation

• Power rail design & regulator sanity check

• Sensor wiring & interface review (I²C, SPI, UART, GPIO)

• Common ESP32 hardware pitfalls identification

Firmware Review

• Project structure & modularity

• Tasking model (FreeRTOS usage, if applicable)

• Driver abstraction & hardware coupling

• Error handling & startup sequencing
