The acquisition of audio signals using MEMS microphones is limited by the length of the data wires. The microphones can be operated on a printed circuit board or at a very short distance from the receiver. Using differential wiring, the range could be extended using standard cabling and connectors (UTP). The objective of this work is to identify suitable LVDS circuits, design circuit boards for the microphone side and the receiver side, fabricate the boards, assemble them and verify the operation. DragonFly 3D PCB printer will be used to print PCBs. One of the task will be to familiarize with differences between design and manufacturing process of traditional and 3D printed PCBs.
Requirements: Printed Circuit Board design basics, Electronics measurements (oscilloscopes, power supplies, etc.)
