N64 USB-C PD Trigger Blank
Description
This is the STL file from a post I made on reddit here: https://www.reddit.com/r/n64/comments/l4bsi7/my_usbc_power_delivery_n64_for_on_the_go/ Here is a quick parts list with amazon links, note I don't make any money off these links, not trying to make money off this just trying to educate. Note that everything can be gotten a lot cheaper from like ebay or aliexpress. Parts list: EBL XL6009 Boost Module 4A https://www.amazon.com/gp/product/B08GSCS2TX/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 XL4015 5A Buck Step Down Converter https://www.amazon.com/gp/product/B079N9BFZC/ref=ppx_yo_dt_b_asin_title_o01_s02?ie=UTF8&psc=1 USB-C Type-C PD Trigger Module 12v https://www.amazon.com/gp/product/B08681QG7W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Notes about what everything does. The N64 power supply simply needs to produce 12v and 3.3v. The USB-C power deliver trigger is used to negotiate with a USB-C battery bank or charger (like the macbook pro charger) and ask it to provide 12v power. One really annoying thing I learned is that it's actually uncommon for a USB-C power delivery charger to support 12v they usually only support 20v and 9v. Even though the USB-C trigger is configured to request 12v, if the charger can't support that it will provide the trigger with 9v instead which isn't good for the N64. So the boost converter here is used to boost 9v to 12v if we so happen to not get 12v from the power source. If we do get 12v then the boost converter will pass along that 12v. The Buck step down converter is used to produce 3.3v from either 12v or 9v. Both of these converters are variable and use a pot to adjust the output. For the output to the N64 I just reused the original one. Note that it has 5 leads coming out of it, but 2 are for ground, 2 are for 3.3v and one is for 12v. The N64 phone were supply actually has the pin out labeled right on it. Everything wired up is very simple, USB-C power deliver trigger in parallel with the two converters. Their out - are all wired up to produce the ground. The out + of the boost converter to the 12v line and the out + of the step down converter to the 3.3v lines. Note you do need a multimeter for this mod since both converters require you to tap in the correct output voltage. Also the N64 requires ~20 watts, so as long as your battery or charger can supply that you are all good! I also made a custom 3D printed insert to hold the USB-C trigger and make the finished product look good. If people are interested I can post the cad file or stl file. Note the 3D print wasn't amazing and I ended up just using hot glue for most of the support, so the file will most likely need some tweaking to be print-and-play. Next I'm going to do a similar mod to my gamecube so I can have one plug for all my systems.
