Ordering EVO PCBs at chinese manufactures questions and help

[scooter8416]

For item #17, IC3   Is this PN OK with the "ROG" added?

 

"Original Part number is incomplete, we will supply Complete part TS2940CP33 ROG ,Please confirm."

 

[scooter8416]

Looks like just a PN revision.

This is great news...!

 

I had a quick search for a STM32H743 replacement (for the HD), but doesn't look like they're currently supporting M7 cortex.

Has anyone found an alternative to this chip?

Also coming up as a zero stock item.

Hi everybody!

 

I’m trying to make my first 128x32 evo order from pcbway. I followed lucky1 video and got bom file back with several component swap. Please, could somebody check those suggestions that they are ok?T-1Y5W462824A-5sets-128x32-BOM(2022-11-16).xls

Why do you want to outsource the work you can do yourself ? Load the datasheets of the original and the replacement and compare. If you find a difference serach this thread if the questions has already been asked and if not you can ask a specific question. 

[nappis]

The idea wasn’t to get ”too easy” with these or anything like that. Allready tried to search. Actually I have investigated quite a lot to get in this point. If I would outsource it would be more easy just buy a plug’n’play device.

 

Maybe I don’t trust for myself with these things enough… ? Quite frustrating to put several hundreds and then it doesn’t work because of one false component.

 

Well, time to start searching data sheets…

In 128x32 evo bom file.

Reason to use ch3.96-4p and vh3.96-4p connectors? They want to put ch-version to both places. Should be quite similar connectors?

[lucky1]

Both CH is also fine as it is compatible with connectors used in pinball machines.

Thanks!

That what I thought also. Maybe just an example in bom that you can use both?

I think all are fine in that file then.

[nappis]

Got this kind of answear from pcbway:

 

”The parts we bought is BLM18KG601SH1D, but your BOM also wrote FCM1608KF-601T03”.

 

To my yes they are bot fine 600ohm 100Mhz but would like to get somebody elses opinion too.

Should work just as good

Now they informed ”soldered STM32F407VGT6 for STM32， pls confirm”

 

To my eyes STM32F427VIT6 in bom file is faster and have 2mb flash instead of 1mb.

 

Is this swapping ok?

 STM32F407VGT6 does also work

Good, thanks.

 

Annoying, they first solder and then asks…

Thanks to the member of the community Jarek we successfully tested 

Geehy APM32F407VGT6 on the EVO 128x32 boards as a replacement for the

STM32F4xx MCUs. As far as we can say from the tests the Geehy APM32F407VGT6 

is pin and binary compatible to the STM chip and should cost between 20 - 25$.

 

Will DfuSe Demo 3.06 work with these MCU's the same as the STM32 MCU's or is another program required?

The latest 64bit pin2dmd.exe tool has DFU integrated which works well with Geehy MCUs. You may have to install a driver using zadig.

All good, thanks

I found the support page on the Geehy website and the DFU driver and programmer are there:

Anyone running a group order of the assembled boards?

 

love to order one but 5 is a little out of my budget.

Does anyone know how to get the pick and placement file as a cpl.cvs type format instead of centroid? I would like to try JLCPCB to make and assemble some board but they won't take centroid format for some reason.

If you import the Eagle file into Altium, you can export one from there

Hi guys

I just had an issue with the activation number for my display.

I thought a "V" in the code was a "U", my rationale was it had straight vertical sides but I was wrong.

Luckily, Lucky1 was understanding and resent the correct code, thanks @lucky1

When i went to load the correct file onto the SDCARD I found a 0Kb file on the SDCARD that was named the same as the correct activation code.

I did not know that the display did this, a very handy thing if there is doubt on what the code should be or to simply avoid a typing error.

 

On further investigation the file is created on startup if the SDCARD is already installed.

I hope this is a help for others in the future.

@lucky1 - I just received my first run of Evo 128x32 boards using the Geehy APM32 processor. I was able to find and install the driver along with the DFU programmer from Geehy's site. I keep getting an error saying "the Vid or Pid of the DFU File is incorrect". The device driver loaded correctly and programmer shows connected in DFU mode. Never had any issue like this with the STM chips. I tried the x64 version of the pin2dmd.exe tool and it says:

 

Match vendor ID from file: 0483
Match product ID from file: df11
No DFU capable USB device available

 

 

At a bit of a loss here...

 

Any help, greatly appreciated!

I'm attempting to order some EVO 128x16 boards from PCBWay. They are asking if there is a substitute for U9 - HEF4020B. Is there an equivalent or alternate for this component?

 

Thanks,

 

Dino Z.

Some similar 14 stage binary counters that should work:
