The highlighted traces is the path from the positive terminal on the battery bay to the DC power jack. This is part of one of them: How power enters the circuit. There are three major things I wanted to communicate with these plans. OK, now for some more technically relevant information. This image shows the back as it is viewed from the back - not inverted as it is in the rest of the plans. This is the front, the whole front, and nothing but the front. I should note that the front is red, and the back is shown all 'x-ray' like in blue.īecause I know not everyone has spent the hours staring at this that I have, I anticipate some of you will still find the previous plan confusing, or only happen to care about one side of the board for some reason. If you're not sure what the symbols, abbreviations, or values are - look for a crash-course later in this topic. I didn't split as many hairs with the silk as with the traces (the red/blue bits) - the purpose of this image is to cross reference the location and orientation of the components because I left the silk out of the rest of the plans for clarity. The font isn't the same, because there's a level of absurdity even I can anticipate. This shows just the traces of the front (in red), back (in blue), and silk screening (in white). This is the more reasonable 'fully loaded' version. Would it fit in your DMG case? Yes, but it'd be a little snug. There are only a couple places that bother me, but I doubt any of you are looking that closely.Īpplicability: If you were to make this board as I've shown and soldered all the bits to it, would it work? Yes. I then went back through and took some liberties with spacing. The initial draft followed the image to a minimum of 1/20th of a mm. I did attempt to get things as accurate as I could. I didn't get it perfect - as in: there's a total of 0.4mm of drift in the image, I hope you can deal with that. I corrected this in Photoshop by re-distorting the image. I can spot a few differences between them, but they're small things that shouldn't matter.Īccuracy: The scans I made had some distortion because it didn't lay perfectly flat against the glass. The gentleman I bought this from sold me his and his brother's, saying he had gotten his, from the store, soon after his brother had gotten his. I know this because I am only the second owner of this gameboy. Source: The gameboy I dissembled had an early production of the sixth revision of the CPU PCB. This does give me the opportunity to tell you a little about the prints you're looking at (or whatever they're called in digital format). The usefulness of this image is less than the others because it's so detailed. Gameboy dmg power switch 1 plus#All 80 hours of work, plus or minus (I'd rather not think about it). (The rest of these images are a lot smaller than the photos, but at beautiful 3125 resolution - just so you can thoroughly appreciate the detail) Gameboy dmg power switch 1 how to#I'll give a crash course later in this topic on how to read this schematic if you're having troubles. I wanted all this to be understandable to someone with only basic understanding of what circuits are and how they work. The biggest thing I wanted when drafting these documents was transparency. Let me know what may need to be corrected. Everything looks right to my eyes, but they may not be as trained as some of yours. (I'll have other quandaries some of you may be able to answer later.īefore I go any further, please know this is the first revision. Without the copper sticker of questionable purpose. But now you get to see the fruits of my labor!Īaaand this is the back. I'll explain more of my motivations later. My motivation for what became a massive project started when I saw some minor inconsistencies between the only information I could find ( which is right here) and what I was seeing while reverse-engineering the poor gameboy you see to the left, but it was more than enough for me to get started. I started removing components before I had the necessary equipment, so some things aren't as pretty as they could be, but I nit-pick. I had been wanting an image like this for a while, and decided to make it myself. This is a scan of the main logic board for the DMG 01.
