Dear, Client. I would like to say this is my fortune to show you my hardware skills. I can bring your idea to live and you can reach the goal absolutely with me. I have 10+ years experience in hardware design (schematic design, PCB design...). My develop tool is Altium Designer, CADENCE. I have designed many high speed devices in embedded system. My recent design is AM5728 Core Board. (quad-core, 1.5GHz, DDR3 4G, EMMC 32G, Gigaethernet, usb3.0,...). And another is PCIe v2.0 to 4x Ethernet (or 4x usb3.1) convertor. All design is passed in several EMC tests. I have designed MEMS tracking board, ultrasonic distance measurement and so on. My design is very stable in industrial environments. I think your design is not difficult. but the most important thing is EMI, EMC. I have been working main hardware developer in large scale industry product company. Designing the PRODUCT is very different from designing the general PCB (test board, kit,...) You can feel everything that is my real skills in hardware development. Look forward to working with you for a long time. Thanks! Hope to see you soon
