lucky1 549 Report post Posted September 13, 2018 I uploaded the Eagle files and BOM list of the new PIN2DMD EVO128x32 controller board to my github account here https://github.com/lucky01/PIN2DMD/tree/master/hardware/EVO128x32 Technically it is based on the schematics of the Nucleo 429ZI board, the V4 shield and the XL4015 DC-DC converter but all on a single PCB which also is used as a mounting plate for the LED panels. I designed it for my private use and ordered a test run from a chinese manufacturer called pcbway. They offer turnkey manufacturing which means that they also source the parts and fully assembles the pcbs. Including tax and shipping it cost me 700 Euro which is 70 Euro for each pcb and almost the same price as the parts needed for the V4 shield, the Nucleo board and the acrylic frame. It can use 12V or 5V as a a power source. The eagle files are free to use for everyone who wants to organize a group buy or sell them in a shop because I still don´t sell any hardware. Here are some pictures of my testboard. 2 dpannell2 and TimBoch reacted to this Tip Share this post Link to post Share on other sites

SteveNZ 16 Report post Posted September 14, 2018 Just looking at the power connectors for the LED displays. Are you soldering the wires onto the board after manufacture at PCBWay? If yes, then wouldn't it be better to have suitable through holes in the PCB to be able to solder the wires with a better physical connection? If no, please provide a photo of the other side of the PCB (with the LED displays removed). Share this post Link to post Share on other sites
lucky1 549 Report post Posted September 14, 2018 No time to remove the panels to make a picture but you can have a look at the eagle files. There are solder pads on the other side. I don´t see a big advantage in throughholes for this. Tip Share this post Link to post Share on other sites

tjc02002 37 Report post Posted September 14, 2018 This is freakin sweet!!! Question, I’ve never soldered surface mount but I’ve seen videos. How would you propose to assemble this? Are there pcb manufacturers that could do the surface mount soldering? Share this post Link to post Share on other sites

How would you propose to assemble this? Are there pcb manufacturers that could do the surface mount soldering? I read your whole post this time! I see you got them assembled from pcb way. Did they assemble everything on the big pcb and then you just added the led panels and cables and then connect the power wires? If everything works well, could you possibly set up a duplicate order for other people just to buy direct from them fully assembled? Share this post Link to post Share on other sites

fly 9 Report post Posted September 18, 2018 Is the controller board, apart from the software, different in construction to stern, williams etc. ?? Thank you Share this post Link to post Share on other sites
fly 9 Report post Posted September 20, 2018 I would be grateful if someone posted a photo of the control board without the display mounted Share this post Link to post Share on other sites

Thank you The board is functionally the same as the V4 shield mounted to the Nucleo STM32 dev. board. The same unit can be used for Stern, Williams, Data East, Sega, etc. I don't believe anyone other than Lucky1 actually has one of these yet. If I'm mistaken, I'm sure someone will chime in shortly.

Dany 1 Report post Posted February 1 Hello lucky 1 I was thinking of making me do the cards evo 128x32 I wanted to understand once made and mounted the RGB panels how to program them, I wanted to know if it is a simple or complex thing and where I can find the program to insert, if you need to unlock them as you did with those that mounted the nucleus and Schield thanks also for all the work you do.

Programming is done through USB DFU mode using this tool https://www.st.com/en/development-tools/stsw-stm32080.html and the nucleo dfu firmware from github. DFU mode is activated by holding down the boot button during power on. Activation process is the same. Tip Share this post Link to post Share on other sites
