Hi boubak,

All ot the elements were bought on ebay, here are the links

This one needs to be modified by cutting off one row of pins

You would also need thermal adhesive like the one below as only the smallest radiators comes with it

This is the thermal silicon pad I’ve used but it’s quite thick (2mm) so probably something thinner like 1.5 or even 1mm would do the job even better it probably depends on the hight of the biggest parts on the back of LimeSDR so you have to measure this.
