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

support@olimex.com

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 support@olimex.com for authorization

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.
