N64 freak Posted April 13, 2019 Report Share Posted April 13, 2019 (edited) Decided to post about my ATX to Xbox adapters as i've been contacted about them a couple times now. I won't build more of them in the future as it's quite a time consuming process but you can order the PCBs and build them yourself. The bill of materials is printed on the bottom layer and assembly is pretty straight forward too. The solder work isn't hard to do so even a beginner is able to get it done! You can order the PCBs here: Rev1.0-Rev1.1 Rev1.2-Rev1.5 The ATX Port and Cables can be reused from a dead (or unused) Xbox PSU and motherboard. The end result might look like this 2 examples here: Edited April 13, 2019 by N64 freak 6 Quote Link to comment Share on other sites More sharing options...

Lavariz Posted December 17, 2019 Report Share Posted December 17, 2019 Do you offer a PCB for the 1.6 revision? Or are either of these compatible? Quote Link to comment Share on other sites More sharing options...
N64 freak Posted December 18, 2019 Author Report Share Posted December 18, 2019 Those 2 designs aren‘t compatible with the rev1.6 boards. I never made a design that is compatible with them. Quote Link to comment Share on other sites More sharing options...
sinclairuser Posted December 29, 2019 Report Share Posted December 29, 2019 with a bit of know how 1,6 xboxes are atx compatible anyway, you dont need fancy boards just a basic rewiring job and some common sense, Quote Link to comment Share on other sites More sharing options...
shawly Posted February 17, 2021 Report Share Posted February 17, 2021 Hey @N64 freak, I bought some of your Rev1.2-Rev1.5 PCBs a few weeks ago. Now I got a 1.0 a couple of days ago and I'd rather use that one for my ultra slim mod, so I wanted to ask if the Rev1.2-Rev1.5 PCBs could technically also be used for 1.0's? Looking at the pinout I don't see why it wouldn't work, but I wanted to ask if there is any difference between the PCBs apart from the Xbox connector.

N64 freak Posted February 17, 2021 Author Report Share Posted February 17, 2021 Only the connector is different. You can rewire a rev1.2-1.4 board to be used with a rev1.0/1.1. You basically only need to attach a single row cable instead of the atx style one and you are good to go! 1 Quote Link to comment Share on other sites More sharing options...
shawly Posted February 17, 2021 Report Share Posted February 17, 2021 That's what I hoped for. Thanks for the quick answer! Quote Link to comment Share on other sites More sharing options...
finalman Posted August 3, 2021 Report Share Posted August 3, 2021 Dirtypcbs lists the size as 10cm x 10cm or you can chose 5x5cm on checkout but the PCBs clearly aren't an even in length or width. So what options do we choose at the screen after we click add to cart? Quote Link to comment Share on other sites More sharing options...
N64 freak Posted August 4, 2021 Author Report Share Posted August 4, 2021 @finalman As the board design does exceed 5cm in one direction you have to choose 10x10. Quote Link to comment Share on other sites More sharing options...
finalman Posted August 4, 2021 Report Share Posted August 4, 2021 (edited) 1. So if we choose the "max 10x10 +$5" The PCBs will be the same size as the ones pictured in the OP? 2. If we order through DirtyPCBs we get 10 PCBs right? 3. DirtyPCBs link is only for the bare PCB/s right? 4. What about the copper thickness is 1oz OK? Sorry for all of the questions but I previously purchased a prebuilt one off of you directly. Edited August 4, 2021 by finalman Quote Link to comment Share on other sites More sharing options...
finalman Posted November 10, 2021 Report Share Posted November 10, 2021 What watt rated resistors should we buy? 1/10, 1/4, etc. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted November 10, 2021 Report Share Posted November 10, 2021 3 hours ago, finalman said: What watt rated resistors should we buy? 1/10, 1/4, etc. The 0603 size of the resistors is going to set the wattage rating of them. I believe that size surface mount resistor is rated at 1/16 or 0.0625 watts. Look at the back of the PCB for the BOM. Quote Link to comment Share on other sites More sharing options...
N64 freak Posted November 10, 2021 Author Report Share Posted November 10, 2021 (edited) The BOM on the backside of the pcb doesn’t state a required wattage for the resistors. The standard 1/10 watt resistors are prefectly fine. No special higher power resistors are necessary as the logic level converter on the board is not handling any real currents but simply does level shifting.

finalman Posted November 10, 2021 Report Share Posted November 10, 2021 (edited) Note to N64... Too late for me as I already purchased PCBs recently but if you update your design again you should join both of the 12v pads rather than just the one. That way if there is a poor/dirty/damaged contact using a 20pin power supply switching to using a 24pin power supply will allow access to the 2nd 12v rail.

N64 freak Posted November 10, 2021 Author Report Share Posted November 10, 2021 @finalman They are connected together already on the pcb design. Quote Link to comment Share on other sites More sharing options...
finalman Posted November 10, 2021 Report Share Posted November 10, 2021 (edited) My mistake as I was looking at the bottom my the PCB I bought a few years ago and couldn't see the join between the two. Also couldn't see it on the dirtypcbs pictures. Turns out it's on the top of the PCB. Edited November 10, 2021 by finalman Quote Link to comment Share on other sites More sharing options...
braxtron Posted April 11, 2022 Report Share Posted April 11, 2022 (edited) What is the FET doing on this board? ping @N64 freak (sorry) Edited April 11, 2022 by braxtron Quote Link to comment Share on other sites More sharing options...

Oh sorry wrong Fett… Fets normally do power modulating tasks. Like dumping excess voltage for instance. They do also have other handy capabilities.

KaosEngineer Posted April 12, 2022 Report Share Posted April 12, 2022 There's a BJT NPN transistor (MMBT3904) and an LM1117 3.3Vdc voltage regulator. What FET? Quote Link to comment Share on other sites More sharing options...
braxtron Posted April 12, 2022 Report Share Posted April 12, 2022 sorry, bjt, not fet. still wondering what the transistor is doing Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted April 12, 2022 Report Share Posted April 12, 2022 1 hour ago, braxtron said: sorry, bjt, not fet. still wondering what the transistor is doing I believe it converts the ATX power supply's Power On signal to an Xbox-compatible Power On signal. However, I don't have a schematic of the board to know for sure. Quote Link to comment Share on other sites More sharing options...
