OpenRefMic v1

Complete implementation to interface an electret microphone capsule with a standard XLR mic input with phantom power.

• Specified PUI AOM-5024L-HD-F-R capsule is the lowest noise electret that is readily available from electrical component suppliers
• Mechanical design that fits within the industry standard reference microphone 1/2" form factor, including PCB, 3D printed parts, and a mini XLR connector
• Documentation showing expected response and specifying filters that can correct the high frequency response of the capsule
• Some originally-planned designs for alternate capsules are referenced but missing, and assembly procedure does not include photos for all construction steps.

This is a snapshot of the project if needed for reference. v2 is currently being designed and should significantly improve the overall usability of the mic.
