UnoCart 2600 v1.03

It doesn't matter, many customers have already placed orders for this project, you can tell your sales representative and we can solder manually.

i have retired this project. it is no longer supported. centroid file is not availabe. please use current version of my UnoCart2.6k cartridge. sorry.

excellent to hear! thanks.

excellent to hear. thanks.

very nice, much appreciated!

I purchased the case on cults3d. However, there's one problem with the design. There's nothing to stop the holder from sliding too far back into the case and damaging the PCB. Mine slid too far back and broke the pads holding c1 in place.

Hello, I'm sorry for the inconvenience, I produced more than 10 boxes and they were used to make unocart, so we did not encounter any problems. I have disabled the design and will make the necessary checks on the design. Corrections will be applied and it will be published again as soon as possible. You'll be able to get it again for free from Cults.

any chance you'd had an opportunity to look at the case design yet?

old board and firmware versions in the pics.

Where to get the new firmware version for board 1.03?

I also got the 1.0 and used the BOM that is posted, just ignore the LED, R2 and R3. Also pin 1 for the stm is on the top left between C8 and C9.

Also for firmware just use the latest .hex file from github dot com/DirtyHairy/UnoCart-2600

Thank you so much for your help :-) I still have problems with microSD_Card_Receptacle_Wuerth_693072010801 ... very hard to find; at mouser.de in Germany these parts are unluckily out of stock. Any idea where can i still find this part ?

I just see they have a new follower part, mouser partnumber: 710-693071020811

I ordered from Farnell. uk.farnell dot com/wurth-elektronik/693072010801/memory-socket-sd-card-micro-8way/dp/2081364?ost=693072010801 but not sure if they have those in Germany. That sd card reader was easy to solder as you can just solder the 4 points on the outside then open the tray and you have easy access to solder the pins.

thanks for helping out with the responses! as mentioned, all parts are the same minuse a few resistors and led, which aren’t necessary, R3 was added to allow a little better compatibility with some micro-sd cards. i was thinking of changing the hinge type microsd slot with a push/pull type. the full size board is almost done, it is working fine with the standard sd card, just some pcb hole alignment issues for fitting into the cartridge case.

Any update on the full size card? If I have version 1.0 can I add the R3 resistor. I can't seem to get any sd cards to work.

@ Sean I had same issue with ver 1.0. I could not get any SD card to work.The issue was solved by adding R3 btw. Pin 4 and 7 in SD slot (couting the pins from left to right). As aSD slot I used those cheap versions https://www.aliexpress.com/item/33013538072.html?spm=a2g0o.order_list.order_list_main.81.90321c24eRTh8T&gatewayAdapt=glo2pol

yes you program the cart with a ST-LINK/V2 programmer. just connect the pins from the programmer to the same pins on the cart.

Yeah, I was wondering if it's only me, who can't find the BOM. Seems to be gone.

i edited the project and added it again, not sure what is going on with the bom, it keeps disappearing from the page. i re-added it once again, let's see what happens :)

it may be that I was uploading it as a csv file and not a txt file, i made it a text file, let's see what happens again :)

sorry, thought I already uploaded it, but it's here now.

Thanks for the BOM. Do you have a cartridge case that can be 3d printed? If not, I'll design one for this. Is the PCB shape the same for rev 1 an d 1.01?

should be able to find a case that may work on thingiverse

Sean, PCB shape remains same size for all revisions. A cart shell would be great, I'm not that great at 3d print designs :)

hi can i have the bom please?

It looks like the BOM gets lost when you update the project, that seems a bit annoying from an UX experience on both ends...

yep, been fixed, missed re-connecting led to ground in a change i made to the pcb, my mishap, i will be uploading fixed version soon. appreciate the reply :)

bom is correct, all footprints are 0603. if you use the correct values with 0603 footprints, you should be fine :)
