Warranty and quality

A control board lives inside your product and carries your brand reputation. These are the commitments GPO makes to every OEM partner.

5 years warranty on every board
0.8% defect rate
100% of boards tested after production

Every board is tested

Each GPO iotHub TPCB control board passes functional testing after manufacturing — before it ships to your production line.

Free replacement

If a board fails for any reason other than incorrect installation, we replace it free of charge.

Component traceability by batch

Components are traceable at batch level, so any production question can be narrowed to a specific lot instead of a whole shipment.

60-day notice on component changes

If we change a component in the design, OEM partners are notified at least 60 days in advance — no silent BOM changes reaching your line.
