I am very glad to get first PCBs from your service. The quality is excelent. So I intend to try develop some products with your assebly service. I read, that it is 10$ mount per PCB, if I use only Seeedstudio units. That is why I need to select their products in my new project. At this moment I got problem. When I search unit throwh "More libraries..." button, in dialog window I have no any filter for seeedstudio components. It is not a signle problem. The second is when I choose processsor stm32f405rgbt6, I saw its price in seeedstudio at your dialog window. But when I visit seeedstruio at their official site, I don't find any MCU of stm32 family at all. So I do not sure, I can order it throw your service succesfuly. Please, tell me right way of cheapest assebling PCBs throw your service. My average projects will be at 300 pads with best regards, Mickle
