Can Hanwu adapt an existing board?

Yes, when schematics, interfaces, constraints and ownership are available. The review determines whether adaptation or a new integration board is the lower-risk route.

Which firmware functions are included?

The agreed function list can cover device states, controls, pairing, reporting, power modes, faults, recovery, OTA and production programming.

How is firmware transferred to production?

Released versions, programming method, configuration data, fixtures, functional checks and issue ownership are defined before the pilot becomes the production baseline.

Embedded hardware and firmware behind finished products.

Hanwu develops connected-product hardware and embedded firmware, including board integration, interfaces, power behavior, device states, reporting, update logic and production programming.

Define Hardware and Firmware Scope Match This Work to a Product

Embedded hardware board, module, firmware workflow and test fixture.

Engineering reference

Hardware and firmware

Keep electronics and device behavior aligned with the enclosure, software and factory tests.

The handoff risk this work resolves

A working module does not resolve board layout, interfaces, power, device states, fault recovery or repeatable programming.

Products that depend on coordinated electronics and behavior

Boards, interfaces, power behavior and device logic built around the finished product.

Ceiling-mounted smart alarm or detection device installed in a commercial room.
