Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Cliff, All, OK, You have got me... Where are the pins labelled DOG? If you mean GDV (*and a spell checker bit you) then the description is in a box about 1" below them. Kind Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

It is where you connect the optional watchdog timer. Just kidding..... As BigMik says, it is a header for Pin33 mainly, along with 3v3 and Ground. I think this is where matherp was going to have 18B20 sensors or something. Smoke makes things work. When the smoke gets out, it stops! |

I've been studying this as I've just discovered the Pi port for the MM If you don't mind me asking. is the 40 pin vertical connector on the left for connecting to the Pi and the horizontal 40 pin connector to plug into an SDD1963? If I'm right what are connections DB7 - DBF for? The reason I'm asking is it looks like the horizontal connector is connected to COM 1? |

@ Grogster Do you still have boards for the Pi backpack. I have nothing to play with at the moment so I bought a Pi. @ Lew Have a look at page 3 of this post Peter has a picture of the Pi mounted on the PCB. Paul.

@ lew247 - Other way around. Horizontal one with the box drawn around it on the silkscreen is the Pi-Zero module footprint - you plug the Pi in there, and anchor it with the four bolts in the corners. The vertical 40-way on the RIGHT of the image above, is for the SSD1963 LCD. The board is designed to piggy-back onto an SPI LCD or to connect to an external SSD1963 parallel LCD via the header, or a short IDE hard-drive cable. DB8-DBF are the connections on the SSD1963 LCD for data-bus bits 9-16, which are not used, as the LCD runs in 8-bit mode, so only uses DB0-DB7 pins. @ Paul - I think so, I will have a look. I never got around to playing with this board myself, as at the time, I did not have a PI-zero. Smoke makes things work. When the smoke gets out, it stops! |

@Grogster The trouble with these projects is they never end ! I would like to buy two of these boards if you still have any. I have two 2.8 screens on two MM Backpacks which I could swap out as I now need "MM + Internet". I am nervous about ordering 10 from China with the manufacturing data as I have no experience of this. If they ask any questions, I'm stuffed. |

Hello. Welcome to the forums. I will have a look in my PCB's. Can't remember if I have any of those left or not, but if not, I can get some more in my next PCB order which I am preparing this week anyway. I will post back here with the results of my search.

@ Volhout: There is no constructors pack or schematic for this, as it is just a blank PCB that you assemble. If you want the Gerbers, I can upload the ZIP file here if that is what you are after, so you can get your own boards made. @ PeterB: Order them via my website on the PRODUCTS page, which will forward you to PayPal, then I can send them out to you. EDIT: Ignore that, PeterB - I see that you already have done just that.... Edited 2019-10-09 10:37 by Grogster Smoke makes things work. When the smoke gets out, it stops! |
