Every item comes with a 30-day warranty. However, there are certain conditions that apply:

1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

1. Provide a detailed description of the damaged item(s).
2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
