What is the Khadas Tone Board?

Khadas is a Digital to Analog convert that converts a digital signal to analog singal. For PCs it converts our digital singal of 1s and 0s to and analog which a speaker system or headphones could understand.

Why would you use such a device?

Audio on lower end motherboards has been known in the past for being riddled with distortion and interference. For the best audio experience a device like the Khadas Tone Board is reccomened. The fine people over at AudioScience forum has compiled a list of measurements and reviews. They will do a better job at explain this subject in depth. ASR Forum

Features of the Khadas Tone Board include:

ES9038Q2M

Khadas Enclosure

The Khadas tone board is sold on Amazon as a PCB and without a case. This put me on a journey to learn to make a 3D model for the device. Using Fusion360 I was able to model a case for the Tone Board.

Features of the Enclosure

• Model in the dimension of the JDS Atom
• Snap fit lid
• Made from PLA material
• PCB stand for support.
• Name printed on the front
• Rounded corners

End results

Some improvments could be made that I will work on

• Thicker walls
• Increase the size of the holes for the RCA to passthrough

Added a version 3 of case with improvements
