Yes, we will official do support for Volumio on VIM3L.

Hi Gouwa,

Thanks, I have one more question on this… will you be releasing the VIM3L boards with Volumio installed on it ?
Cause then I mite as well wait for the release of those boards instead of picking them up now?
Whats your suggestion on this ?

Thanks

Still not sure at the moment, as the Volumio OS on VIM3L will be slightly later then Android / CoreELEC OS on VIM3L.

@hyphop will work on the Volumio OS soon.

On Android I use an app called USB Audio Player Pro.
It allows to bypass Android SRC with the self developed driver and in addition integrated with Tidal and MQA for de-compressing and hi-res streamming.
Once you purchased it in Google Play, you can use it on any of your android device. Either on DAP or VIM.
I am not sure how KTB will behave with it though.

On my andriod I use PowerAmp which is made for devices with HiRes DAC’s since my device has a dedicated DAC. But it is a single player for single device.
Even Im not sure about the Toneboard.
Ive heard good reviews of the Toneboard and hence Im trying to build this network player device.
Not sure when will the Volumio for VIM3L and Toneboard be out and how will it perform though. Theres no word out as yet.

Tone board is an excellent candidate for this project. Its the best I have heard and has now replaced my Mamboberry board in my main system. Its simple to setup and good value for money compared to similar performance cards.

i think we can see VolumioOS soon ! we cooperate with volumio team already !

at this moment im testing vim3+tone on another special audio OS, and check all hardware for best compatibility - i will share them soon same

Ive ordered the Tone board, will have to wait till it arrives.
Many other DAC’s use seperate Reclockers as a buffer to accurately match the clock frequencies to minimize jitters.
How is the Tone board when it comes to recreation of hi fi audio. I dont see a reclocker in this board and I dont know if it is really required. Whats your take on this ?

Hello Khadas team.
I will be designing an Aluminum housing for the VIM3L+tone board audio streaming endpoint player.
Since there is a Al. housing, I guess the supplied antennas wont be effective, so I was thinking of using an external mounted antenna screwed on to the housing and connected using the Ipex connector.
Do you have the antenna specifications ?

It achieves better objective measurements without the need for a reclocker. Bare in mind that almost all of these boards are designed to work with a pi which has very unstable clocks as standard. So my opinion would be that these are solutions for another product not the VIM. Also bare in mind that those who have tried to improve on the performance with expensive external DC power supplies have actually degraded the sound - which should tell you that this is a top flight engineered product with a attention to detail seldom seen in the class.

It stands up against hifi products costing a grand so I would say its going to do your job.

I was actually thinking of using a Linear power supply instead of the smps that comes with the VIM3L.

There is an extensive thread discussing using a external 5V supply with the results people achieved.
However since moving over to a digital amplifier with built in digital smtp power supply - I am no longer afraid of using a “good” smtp.

What will be the power requirement for the VIM3L+Tone board+ Touchscreen +wifi?
I had read on some threads that the VIM3 boards can take from 5V to 20 V- and recommended is 12V
But the power supply that is being sold with the VIM3L boards is a 5Vx 2A =10W power supply.
So what will be the peak power drawn with all the components in use?
Should I go for a 12V or a 5V ?

Hi @Gouwa
Do you have the specs of the antenna thats supplied with the VIM3L ? Thanks

Hello, The Khadas 24 watt PD power supply will also work on the VIM3L. Requires USB-C to USB-C cable. Typically it defaults to 12vdc on the VIM3, I assume is true for 3L too.

Normally with USB C there is a power negotiation between the load and the power source, and hence you have to have a good comparable cable. This was mainly for quick charging of batteries. Does any power negotiation happen also with the VIM boards? Or does the VIM board lock at a fixed voltage ?
From the old threads what I see is if you want to power using the type C you can supply 5-12V , or 12V via the VIN molex connector ?
I wanted to use a better DC power supply instead of using the Type C. But what specs 12V 2A ?

If I recall, the VIM3 and 3L negotiate with the PD PS, default on the VIM3 is 12v, that can be changed(?).
Yes, from what I read, 12v can be applied to the USB-C or the VIN connector, I assume this is true for the 3L too.
Khadas PD 24w outputs…
USB Power Delivery Output: 5V at 3A, 9V at 2.67A, or 12V at 2A

@kenny will response here.

Once the board comes ill check how it performs.
