Hi everyone! I'm finishing a library for the controller chip, so I can make a custom board using it, for me at least it will be very useful, if anyone is interested, I may upload it here. It's not hard to do, I know, but it's boring, takes some hours of our days lol. Of course I still have to test it on a printed board to see if the pads are really alligned, but they do seem in place. I'm using as a reference the controller pinout from here. I intend on doing a smaller board, and pinout for the controller pak I modded to not use batteries. Do you guys think it's worth it? Edit 1: Spoiler Since I plan on making the custom board, I mapped the controller pak as in the image: Pins are as follow.: Spoiler: Pinout 1 = E2 2 = E3 3 = E4 4 = E5 5 = Battery? Have to test more 6 = E7 7 = E8 8 = E9 9 = E10 10 = E11 11 = E12 12 = E13 13 = E16 14 = GND 15 = E32 16 = E30 17 = E29 18 = E28 19 = E27 20 = N/C 21 = E26 22 = E25 23 = E24 24 = E23 25 = E22 26 = E21 27 = E20 28 = Seems to be VCC The U1 chip, named PWIC, seems to be a step down, but I didn't find anything about it online yet, 99% sure it's just a converter. The bigger white box named C1 connects to pin 31/15 VCC, and to ground. Not sure if any of those are necessary to function, or if the chip can work on it's own, when connected to the E-pins. As far as I can tell, the FM28V020 works by putting it in place, that's what I tested. By it's datasheet, pin 28 really is VCC and it works off of 2,0 to 3,6 V, and should be 3,3V. The datasheet also says.: "A 0.1uF decoupling capacitor should be placed close to pin 28 (VDD) and the ground side of the capacitor should be connected to either a ground plane or low impedance path back to pin 14 (VSS). It is best to use a chip capacitor that has low ESR and has good high frequency characteristics." Edit 2: Spoiler So I will make/have someone to make this board, here it's a picture of it, if it works I will share here the board layout + the libraries I made for the project (The cap I will use is not ideal on the memory chip, but here it's hoping lol). The buttons placement is a mess, didn't have much time to organize that, the board can probably be made smaller, but I'm not particularly good at this board designing thing. I could share the groundings, I could make the analog connections pins instead of pads... And a lot of other improvements. Anyway let's see if it works... Edit 3: Spoiler So, while I wait for MONTHS, for the board to arrive in my country, I will list a few things here for a next revision of this board: Integrate the board with the analog solution for the N64 (Analog stick, micro controller etc) Redo (remove) the many ground pads, which are unecessary space on the board DONE Release the files on my github page Release a bonus design which I'll use on my own portable, integrating all the buttons, aswell as the analog sticks in one board, ready to be placed on case. Add also the rumble functionality aswell as the already present on the board controller pak, but since I don't have those clone paks that have this functionality, I won't do this for now. But will be a nice feature.[/S] Here it's a picture of the new board design, without the unecessary ground pads.
