Hi, I'm an experienced embedded and electronics engineer with over 20 years of experience. I can create your Pi Hat with 3 microphones and ADC. I can design the circuit and provide a PCB design with a parts list (bill of materials) and Gerber files (PCB manufacturing files) ready for manufacture - or, if you wish, I can provide a ready-built prototype on the final PCB. The PCB will be designed to reduce the amount of noise the ADC will pick up. I have a high level of attention to detail and will produces results that are right first time. Message me now and we can discuss the details and a possible cost reduction. Thanks, Joe
