ESP32 Manufacturing Readiness Review (Firmware + Test Plan)

Description

This service is for ESP32 product teams preparing for their first manufacturing run or struggling at the factory-line stage.

If your product:

• Works in engineering but fails during flashing or testing

• Has no clear factory test or provisioning flow

• Relies on tribal knowledge instead of documentation

• Is hard for manufacturing or support teams to diagnose

This review bridges the gap between prototype firmware and production reality.
