I know some are impossible, like the processor, but capacitors, resistors, diodes, etc could be. Possible yes but would be a lot more expensive for manufacturing because of no automatic placement but manual placement of the components. So does not make any sense 1 Link to post Share on other sites

yenningComity 0 Posted February 23 Share Posted February 23 Want to order of pcbway, but wanted to make sure that the evo board listed is the current version. They dont list when it was last updated or a version number on their site. It just shows when it was first uploaded. Link to post Share on other sites

Peza 0 Posted February 24 Share Posted February 24 ordering 5 of 128 x 16 evo boards and get this from them.. have uploaded both centroid and bom file. but cant find any info on this.. Link to post Share on other sites
lucky1 875 Posted February 24 Author Share Posted February 24 The partnumbers they are refering to are not SMD but THT (Throughhole). Tell them to look at the BOM. 1 Link to post Share on other sites
Thargor 0 Posted March 8 Share Posted March 8 (edited) Hi Guys I have ordered also 10 Pin2DMD Boards by PCBway. Now the send me an email with a few questions, perhaps @lucky1 can answering them. see attachement, especially the two picture with these red arrows. Thanks rrow pointing cathode please confirm arrow pointing the cathode Edited Sunday at 12:22 PM by Thargor Link to post Share on other sites
Ashram56 3 Posted March 8 Share Posted March 8 Just ordering a new batch of PIN2DMD, they are requesting some changes of the BOM. Some are pretty straightforward (diodes, headers), one is more concerning Specifically: they want to change the voltage regulator (IC3) to AZ2940D-3.3TRE1 Looking at the datasheet, it seems to me this new regulator has lower characteristics, ie max input voltage is 16V (recommended max 13.2V) compared to the original regulator (26V). That said, checking the schematics that should be fine, since the input voltage is 5V anyway, right ? Cheers 1 Link to post Share on other sites

Thargor 0 Posted March 8 Share Posted March 8 I think you mean this post: I see there is no differenz between my board and that posted above... looks like the same.. but I´m not the speciallist like you ? Link to post Share on other sites

If you check the sample order folder when you download the order zip off GitHub it will have some pictures in there that you can compare to. They are a good resolution so you can zoom in too. This will help you check orientation of parts etc and it even has arrows for the cathode and anode. Link to post Share on other sites

Ashram56 3 Posted March 9 Share Posted March 9 @lucky1 , could you please provide a PN for a female connector that would fit the existing WPC 12V male connector on PIN2DMD ? Or alternatively, could you please confirm this reference is correct: VHR-4N | Boitier de connecteur Femelle, 4 contacts 1 rang pas 3.96mm, Droit, Montage sur câble, série VHR | RS Components (rs-online.com) Thanks Link to post Share on other sites

It is called VH3.96 Link to post Share on other sites
antoniomauro 1 Posted March 23 Share Posted March 23 Hi, i'm a little in trouble to check this equivalent components proposed by pcb way: original BOM: FC4SDCBMF8.0-T1 -> Proposed: 6CS08000F20UCG (lower load capacitance) original BOM:TS2940CP33 -> Proposed:AZ2940D-3.3TRE1 (many voltage difference) original BOM:SK54BTR -> Proposed: SK54B (maybe identical?) Thanks to everyone!! Link to post Share on other sites

Thargor 0 Posted March 25 Share Posted March 25 Hi today my package from PCBway arrived, but something went wrong.... I only have the pcbs without LED assembly so whats going wrong by the order? Link to post Share on other sites
dzorbas 18 Posted March 25 Share Posted March 25 There's nothing wrong with the order. You need to source the LED panels separately and build the displays on your own. PCBWay only builds the boards and does the SMT work for you. Link to post Share on other sites
Thargor 0 Posted March 25 Share Posted March 25 Ok. thx.. and where can I get the LEDs and all other parts for that what I need like this one: https://de.aliexpress.com/i/1005001837366586.html?spm=a2g0x.12057483.0.0.131db3b9qkLQxK Link to post Share on other sites
dzorbas 18 Posted March 25 Share Posted March 25 Try this link for LED panels... https://www.aliexpress.com/item/1000001223755.html?spm=a2g0o.productlist.0.0.1e332129Ul1U0L&algo_pvid=b22f620c-bdfb-4165-b5ff-2f52d6b2bf65&algo_expid=b22f620c-bdfb-4165-b5ff-2f52d6b2bf65-0&btsid=0bb0622d16166835069594025e6cf7&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Link to post Share on other sites

goredaimon 2 Posted April 12 Share Posted April 12 Today I received an question about the centroid file: "there are some designators location in Centroid file and location on silkscreen layer not corresponding. Pls provide new Centroid file with correct component location." I just used the files from the PCBWAY_ORDER_EVO128x32.zip as I did at my first batch. I'd like to know what is going wrong.

lucky1 875 Posted April 12 Author Share Posted April 12 I never had or heard a problem like this beeing reported. There are two different centroid files in the zip. One in mil and one in milimetern (mm) Mybe they took the wrong one. Link to post Share on other sites

After I sent the files from github, I got this answer from pcbway: However, the files you update Centriod file can't corresponding the Gerber file you upload previously. The PCB we manufactured as per previous Gerber file. Is you mean re-make the boards as per new Gerber file ?
