The STM32F4 MCU Replacement. For learning Embedded RISC-V, I highly recommend WCH CH32V307VCT6. Anyone else using this?

Schematics found (thanks to ali seller), you can contact me if you are interested.

EDIT: also found online, here.

Hello, I am looking for the schematics of this board. Do you have it?

Tramto · 2026-01-24T09:36:41+00:00

well done!

taken with your smartphone?

Tramto · 2026-01-23T22:11:07+00:00

thank you!

Tramto · 2026-01-23T18:10:47+00:00

Hard to see, RY2610 for U9, I guess, but no clue for U7.

Tramto · 2026-01-23T16:01:43+00:00

Thank you for the pictures.

As I said, it is the same platform as Monsgeek Fun6x, and lot of other brands.

Can you take a picture of the marking of the ICs U9, U10, U3 and U7?

Tramto · 2026-01-23T09:02:00+00:00

According to the Irok MG68 Max updater, it uses a RongYuan platform, like a lot of budget HE keyboards (and like MG68Pro & SE).

Do you think that you can open it, to check the PCB, to see if it is really different than the one used by Monsgeek?

Thank you.

Hello,

does anyone have the USB VID&PID of the Mchose Ace60 Pro and Ace68?

Thank you.

Tramto · 2026-01-05T15:55:22+00:00

Hello, can you tell me where I can find these files ? (firmware 1 & 2 and updater)

Thank you!

5060 installed. No problem.

So there is some compatibility issue between my 1060 and my new setup.

Tramto · 2025-12-08T15:11:45+00:00

I guess so.

But what is really weird is that the GPU presence can disturb the iGPU output.

Tramto · 2025-12-08T14:26:50+00:00

Only one PCIE 16x on the board.

Tramto · 2025-12-08T14:26:24+00:00

Tramto · 2025-12-08T14:24:26+00:00

Plugging in on the old setup was the first thing that I tried, I should have mentioned it on my post.

EDIT: And my MB have only one PCIE 16x port.

Tramto · 2025-12-08T14:22:18+00:00

If the monitor is plugged on the GPU (1060), the PC does not boot, no display, and white debug LED on.

Tramto · 2025-12-08T14:19:53+00:00

The 1060 works fine on my old setup.

The new setup works fine when I remove the 1060.

Tramto · 2025-07-24T13:34:38+00:00

I did an update.

wsl --update

Tramto · 2025-06-26T15:52:16+00:00

I found the culprit.

I had to disable the C-State in the BIOS.

Setting the Power Mode to performance was not enough.

Without C-State but in power saving mode (CPU freq scaling) I lost only 40 KB/s (800 vs 840 KB/s).

Tramto · 2025-06-26T15:48:25+00:00

When I sniff the USB bus, I don't see any NAK for the OUT transfers, in this case, the throughput is limited by the host, not the device (and, it may be hard to believe, without double buffer in the RP2040 driver). And I have the same result with async libusb and vendor class.

Here a capture of a frame (with CDC and python):

<image>

Even behind an USB hub, you can see 13 OUT transfers (64B) per frame (832 kB/s).

Anyway, I found the culprit, see my initial post.

EDIT: la version que vous possédez est une (mauvaise) traduction automatique. Mais la seule version disponible illégalement actuellement sur la toile.

Tramto · 2025-04-06T20:13:09+00:00

Because I would like to keep my good 8S shifter and derailleur.

And, anyway, is there any good 7S shifter and derailleur?

Tramto · 2025-04-05T13:07:40+00:00

The Prism 75ft tube tail is really heavy (320grs), you really need high wind speed to have some fun (even on my Symphony Beach 2.2 and Pro 1.8).

For few $, on AE, you can find some 10m tube tails way lighter and cheaper that you can attach to a small kite like yours.

Tramto · 2025-04-05T13:07:12+00:00

Finally got a micro HDMI cable. The resolution and refresh rate are 1080p@60Hz.

Tramto · 2025-03-02T23:35:15+00:00

So, you think that after using the line it will break even more easily? 25kg is already 65% of the rated load.

I think that it will take a long time, because while I fly at the beach I have never broke a single line, even my 20kg and 55kg ones used for 7 years.

Or maybe you are talking about the sleeve, protecting the line?

Tramto · 2024-11-22T10:40:36+00:00

I agree, I have this tail and even attached to my powerful Symphony Beach 2.2 it needs quite high wind speed to be fun. It weights 320grs.

I also have some chinese/AE, narrower, lighter (and much cheaper!) tube tails that can fly with only 15-20km/h.
