You have an idea for a hardware device and a proof of concept. The next thing you need is a PCB designed for manufacturing. We have a lot of experience in designing multilayer PCBs for commercial devices. In addition to functional requirements, we also pay attention to EMI, thermal, and signal integrity requirements during design. Usability and aesthetics are also key factors for us. We use both Altium Designer and kicad for our projects. We have in-house facilities for assembly, board bring-up, testing, and small volume prototyping of your hardware.
