Customer Support
Report a quality or after-sales issue
Document the issue and keep the affected items available for review.
Record the evidence
Take clear photos of the affected boards or parts, labels and packaging. Note the quantity affected and describe the observed problem. Identify the order number and design revision supplied for production.
Contact support promptly
Email service@esp32s.com with the evidence and a concise description. If the issue concerns a measured dimension or test result, include the measurement or test method and expected result.
Agree on next steps
Keep the affected items and original packaging. Ask support for the investigation and any return instructions before shipping items back. The applicable remedy and terms need to be confirmed for the individual order; opening a support request does not automatically approve a refund or replacement.
