About the Xiegu-MiniMic PCB
Xiegu-MiniMic is an open source PCB design by jzkmath, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 50.8 × 25.4 mm, with 18 components from 12 distinct parts.
By type, the board carries 10 capacitors, 2 diodes, 2 resistors, 1 connector, 1 microphone and 1 switch.
From the project
A Small Microphone for the Xiegu G90, X5105 and X6100 Radios
After looking at the larger Microphone that comes with the radio, it appears to be a clone of the ICOM HM151 Hand Mic. Knowing this, I was able to use the service manual to create this PCB.
This is designed using KiCad Version 6.0.9
The Enclosure can be 3D Printed and requires 4 M2x20mm Socket Head Screws and 4 M2 Nuts. I used McMaster Carr Part numbers 91292A013 and 90591A111 for this project.
