Hi all, I would like to share how I upgrade the Chord Mojo to have Bluetooth Receiver and USB C Connector.

As suggested by the previous post, I use XDuoo 05BL Pro and create a 3D printed casing for the PCB and Batteries. The result is something similar to Chord Poly, but smaller. After the upgrade:
- Bluetooth receiver up to LDAC, auto quality is very similar with direct DAC
- Media control button
- USB C Charging port for both XDuoo and Mojo
- USB C DAC port for Mojo

The CAD file for the casing and the step by step is also being shared under this blogpost link. Please do give your comment or suggestion for this project.

Excellent .
I did something similar, though not this elaborate .
Just get a poly sleeve and paint it matt black for looks.
Well done.
Why are there two batteries?

There are one battery for the Xduoo 05BL Pro and another battery for Chord Mojo. I use the original USB C charging port on Xduoo 05BL Pro to charge both devices, the 5V is tapped from its PCB and connected to the micro USB cable that connects to the Mojo charging port.

This way connecting a charger to the Xduoo 05BL Pro port charges both devices.

OK I got that about the plugs and sockets and charging bit.
What I don't get is that Mojo has a battery builtin, why did you add another?
To give it a cleaner power?
To give it a longer play time?

No, I did not add battery to the mojo, I use its original internal battery for it, the battery you see attached to the PCB is the original battery from XDuoo 05BL Pro.

On the power side the only mod is to connect the 5V from the XDuoo to the mojo charging port. Take note that this 5V supply is only active when you charge the XDuoo via its USB C port, this way it charge both device at once.

Incredible. I'd buy this over the Poly any day of the week.

I thought this was a battery too!



I was thinking of putting the same BT module into this:



This is not Poly! this is from Mojo cable pack, which is basically the shell from a Poly as a passive adaptor to connect USB and other stuff to Mojo.
There is plenty of empty room inside for the module, and microUSB sockets and plugs (straight wired) and a simple plastic line (similar to a thick fishing line) that acts as a sort of optic fibre to relay mojo's battery-life LED to the outside.
It would have almost been a Poly knock-off! no WiFi, but better BT connection.

Or just use a battery powered Bluetooth receiver with a toslink output and use a toslink cable into the Mojo2.

Finding such a device is the hard part.

This is one example. It has multiple outputs and might be bulky but it sure has flexibility.

the "UGREEN" is actually USB micro to USB C converter to convert the DAC port to USB-C.

Ya, my initial planning is to get the Mojo cable pack, but it's a bit hard to get here in Malaysia, so I go with 3D print.

It's actually quite easy to put together if you have 3D printer, you can download the CAD file from the blogpost.

If you can find one of these.- I used one waiting for Poly. It has a Toslink out, but it’s still only Bluetooth:

BT is compressed music!
Best BT codec I have heard is LDAC - and even that is not CD equivalent in sound quality terms, eventhough it goes 24/96.
Anything less, is for casual listening, hence why network streamers are so much in demand, they can be bit perfect.

Bravo. Talk about some un disruptive modding!

Hi i'm looking for a small portable power charger/source for the mojo so i can run it without the internal battery which has died.

Which is the best choice (must be easily available in UK)

thanks

Could you get a replacement battery? The size of the mojo is so nice, i wouldn't want to lug around something else.
