Content Provider lucky1 Posted October 25, 2015 Author Content Provider Share Posted October 25, 2015 LMAO looks like the price of the display boards have nearly doubled. Ugh. This project just went out of my price range unfortunately. $122 bucks for the displays, $26 for the discovery board, $27 for the parts, $80 for the pcb is around $250. I don't know what the hell happened to the price on those displays. Unless someone has an alternate source I'm probably out The reason is that you get 160x160 panels for the price which consist of two 80x160 panels in one frame. You can remove the pcb from the frame by unscrewing and put them side by side in a self-made frame or by cutting the frame in two. You can also order the PCB from china for 60$ for 10 pcs incl. shipping to the US. I have a contact in alabama who already did this. http://de.aliexpress.com/item/P2-5-Indoor-full-color-LED-module-1-16-scan-SMD-2121-3in1-RGB-160-80mm/32475082626.html?adminSeq=220102268&shopNumber= Link to comment Share on other sites More sharing options...
Content Provider freneticamnesic Posted October 25, 2015 Content Provider Share Posted October 25, 2015 Oh so that one is 64x64, it's two 64x32 matrixes in a square frame, so you just re-position them. The other links said 64x32 for $50ea but the pictures looked like 64x64. The new link is much better thank you. so really about 180, unless a couple friends want to buy my extra pcbs! that's a better price or how many people are going to do this? lucky1 are you going to provide pcbs or can I set up a group buy? I can drop the PCB price to about $20 + shipping if I buy more than 10 at a time. (this is not including any of the connectors soldered and installed, just the pcb board) Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted October 25, 2015 Author Content Provider Share Posted October 25, 2015 Private group buy is no problem for me. If you want I can ask my contact to arrange a pcb group buy in china. Link to comment Share on other sites More sharing options...

Content Provider freneticamnesic Posted October 25, 2015 Content Provider Share Posted October 25, 2015 OK let me sort some things out, I can do the bare pcb and everyone solders their own, or I'll have a local shop quote assembly and I can give the price of the whole pin2dmd pcb assembled. I'll only do 10 of these either way. once I quote the assembly I'll let you guys decide what to do, I'm comfortable soldering my own board but not sure how everyone else feels about that. If we buy the panel from aliexpress, we just need the HUB75 connector, correct? that would save some money on the parts Link to comment Share on other sites More sharing options...
Content Provider gtxjoe Posted October 25, 2015 Content Provider Share Posted October 25, 2015 Lucky, Do you have a picture of the back side of the populated circuit board and a quantity on the parts actually needed for the build? Also the 16 pin header, what is that used for? Fren, I can solder my own Link to comment Share on other sites More sharing options...
Content Provider CarnyPriest Posted October 25, 2015 Content Provider Share Posted October 25, 2015 Yes, count me in. Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted October 25, 2015 Author Content Provider Share Posted October 25, 2015 The pcb from github is single sided layout with one wire bridge. You can contact UncleSash about the china PCBs . I think he already ordered 10 pcs. He also improved my layout in eagle and made the part list for the US. The 14pin header is for classic pinball interface. The second 16pin header is for HUB08 pinout display panels. Lucky1 Link to comment Share on other sites More sharing options...

boiydiego Posted October 25, 2015 Share Posted October 25, 2015 can the connectors not be directly placed and solderd on the board without using the pcb ? Link to comment Share on other sites More sharing options...

Blashyrk Posted October 25, 2015 Share Posted October 25, 2015 I just ordered a 16 pin header and a bread board, my plan is just to solder the wires from the stm32 to the 16 pin header Link to comment Share on other sites More sharing options...
Content Provider freneticamnesic Posted October 25, 2015 Content Provider Share Posted October 25, 2015 Yep that would work. I hate soldering little wires. Do you need the sd card reader? Maybe if that's not needed this could be done with a custom cable. I'll look into that, too. Link to comment Share on other sites More sharing options...
Content Provider gtxjoe Posted October 25, 2015 Content Provider Share Posted October 25, 2015 If you go minimal for a pinMame setup only, then you might only need this cable as Lucky1 mentioned to connect the Discovery to the LED module (HUB75 16pins). 5V power, ground and usb cable. I guess you just need the female to female ribbon cable from this bundle http://www.ebay.com/itm/181846678573 Link to comment Share on other sites More sharing options...

Content Provider UncleSash Posted October 25, 2015 Content Provider Share Posted October 25, 2015 Hello Folks, I have worked together with Lucky1 at the PCB Layout.My homebase is located in Tuscaloosa, AL. I'm an electrican, with a big experience in design and solder from PCB boards. When anybody wants.... I can make an order list and order everything from CHINA. But before, you have to know:Minimum order is 10, that means: Minimum 10 people must order the PCB Board, 10pcs is the minimum quantity for a prototyp order.It takes about 4 to 6 weeks to get the boards and to send to your post box.Shipping is ONLY available for the US and Canada (higher shipping costs to Canada). I have no price right now!But i think it is something between $25 and $75, depends on the Board setup (incl. shipping). However, I will calculate the costs in more detail when I start the new ordering thread. And I write down all costs, that everybody knows how less money i made with this stuff :-) Look at Post #128! I can offer the following services: Packages: (PCB Layout is attached) complete set (all parts soldered , with STm32F4 Board, code allready loaded to the controller and tested with my RGB LED Display) 2 Layer PCB Board only 2 Layer PCB Board with parts, NOT soldered 2 Layer PCB Board with parts soldered 2nd option (layout is attached NOT 1:1!!!!):I designed a 2nd 2-Layer PCB Board, it cost the double from the single Layer PCB Layout, with name etched on the board,so it's ESAY to find the correct Headers.But I can offer only this 2 option on the 2nd one: complete set (all parts soldered , with STm32F4 Board, code already loaded to the controller and tested with my RGB LED Display) PCB Board with Parts soldered Give me some feedback.If I have more than 10 people together who want a board, then I start a new thread for ordering the Boards! Look at Post #128! Best regards Link to comment Share on other sites More sharing options...

Content Provider CarnyPriest Posted October 25, 2015 Content Provider Share Posted October 25, 2015 I don't mind soldering my own, but of course if someone is willing to produce a plug 'n play solution then I'm all in.

Content Provider gtxjoe Posted October 26, 2015 Content Provider Share Posted October 26, 2015 Here is the schematic for those curious. From lucky1's github repository PIN2DMD_sch.pdf Is the SD Card for SmartDMD support only or something else? Link to comment Share on other sites More sharing options...
Content Provider UncleSash Posted October 26, 2015 Content Provider Share Posted October 26, 2015 As far as i know is the SD Card for the RGB function. The Software saves the Colortable on the card. So it is necessary to run the RGB DMD. I hope your question to the SD Card is solved. Anyways, the SPI-MicroSD adapter cost on eBay only $1.00 (china) to $4.00 (USA, and is the same as from china!)... best regards Sascha Link to comment Share on other sites More sharing options...
