For product support, hardware information and error reports mail to: 

[email protected]

. All document or 

hardware feedback is welcome. Note that we are primarily a hardware company and our software support is 
limited. Please consider reading the paragraph below about the warranty of Olimex products.

All goods are checked before they are sent out. In the unlikely event that goods are faulty, they must be 
returned, to OLIMEX at the address listed on your order invoice.

OLIMEX will not accept goods that have clearly been used more than the amount needed to evaluate their
functionality.

If the goods are found to be in working condition, and the lack of functionality is a result of lack of knowledge
on the customers part, no refund will be made, but the goods will be returned to the user at their expense.

All returns must be authorized by an RMA Number. Email [email protected] for authorization number
before shipping back any merchandise. Please include your name, phone number and order number in your
email request.

Returns for any unaffected development board, programmer, tools, and cables permitted within 7 days from
the date of receipt of merchandise. After such time, all sales are considered final.

Returns of incorrect ordered items are allowed subject to a 10% restocking fee. What is unaffected? If you
hooked it to power, you affected it. To be clear, this includes items that have been soldered to, or have had their
firmware changed. Because of the nature of the products we deal with (prototyping electronic tools) we cannot
allow returns of items that have been programmed, powered up, or otherwise changed post shipment from our
warehouse.

All returned merchandise must be in its original mint and clean condition. Returns on damaged, scratched,
programmed, burnt, or otherwise 'played with' merchandise will not be accepted.

All returns must include all the factory accessories which come with the item. This includes any In-Circuit-
Serial-Programming cables, anti-static packing, boxes, etc.

With your return, enclose your PO#. Also include a brief letter of explanation of why the merchandise is being
returned and state your request for either a refund or an exchange. Include the authorization number on this
letter, and on the outside of the shipping box.

Please note: It is your responsibility to ensure that returned goods reach us. Please use a reliable form of
shipping. If we do not receive your package we will not be held liable.

Shipping   and   handling   charges   are  not   refundable.   We  are   not   responsible   for   any   shipping   charges   of
merchandise being returned to us or returning working items to you.
