Antminer s19k_pro - no sd card slot?

[nexxypoo]

Hi everyone,

I just took delivery of my new s19kpro and wanted to run it with braiins OS
...however, contrary to the official bitmain manual and pics, the sd-card slot is not there. Instead, there is a microSD connection.
Any ideas on how to overcome this? I tried using an SD card reader with micro-sd connection, but it doesnt appear to work

Any and all help very much appreciated!

There is no such thing as a 'micro SD connection'... Did you mean a micro-USB connection?
There *is* a micro-SD card and slot.

I haven’t gotten my hands on a S19K Pro yet, but I believe they come with Amlogic control boards that don’t have SD Card slots.

If you want to Run Braiins or any of the other aftermarket FW, I think you need to get a new control board.

I guess he meant the microSD card slot.
But its a bit confusing for me aswell.

To OP:

I just checked the docs of Braiins+ OS and it seems like the S19K Pro is not supported. No guarantee though, as I don't know exactly when the documentation was updated.
This may be because the S19K Pro uses an Amlogic control board, as @skot also suspected.

He means Micro USB, the Amlogic C76 A113D has no Sd/Tf card slot, only a Micro USB, regardless, as Phill mentioned above, the k version is not supported by BraiinOS yet.

I also have a paranoia over the letter K in any Antminer Bitmain makes, this letter brings back sad memory of the S9k, I think k stands for KABOOM!, Bitmain collects all the bad chips and stick them on all the bad control boards they have and ship them to us like hot potatoes.

Rumor has it you can run LuxOS on a S19k Pro with the Amlogic control board; https://x.com/LuxorTechnology/status/1712838137041277139?s=20

I have only seen this miner with C74 (Zynq) same one used in some S19A. This control board has two fan plugs that are thicker, to acomodate higher amps. I would not advise changing this control board and keep using the same fans with some adapter, you may burn it.

It is NOT supported in Braiins OS+ yet, work is currently in progress. As always, any new miner model/variation needs to be carefully studied and tested to have a reliable clean implementation.

The faster others release, the more you should worry about them taking shortcuts. But its your miners at risk, YMMV...

Braiins just introduced that the newest version won't need SD card and you can install remotely!
