Report a quality or after-sales issue

Record the evidence

• Order number, design revision and affected item or batch labels.

• Clear photos of the boards, parts, packaging and observed issue.
• Expected result, actual result and relevant measurement or test method.

Contact support before returning items

Email service@esp32s.com promptly. Keep the affected items and packaging. Do not return or modify them further until the investigation or return instructions are agreed.

Investigation and resolution

For custom PCB and PCB assembly orders, return eligibility, warranty scope and any remedy are confirmed against the written order agreement, agreed specifications and investigation findings. PCB32 does not publish one universal return or warranty duration for every custom project.

A support request does not automatically approve a refund, replacement or repair. Support will confirm the proposed next steps, any return authorisation, cost allocation and timing in writing. Existing order commitments and rights that cannot lawfully be excluded remain applicable.
