usb-c charging for 3ds/3dsxl/new3ds/new3dsxl --- ![front side](pictures/front.png) ![back side](pictures/back.png) what? --- a pcb that lets you convert a 3ds to usb type c charging ok cool i want one --- now comes the unfortunate part... this pcb uses *castellated holes* which adds a large base price when ordering it. (e.g. 5 of these cost ~37€, 30 cost ~40€ at jlc as of this writing) if you know me irl i have some of the v1 boards left over, they have some flaws but they work v1? the pcb says v2?? i'm confused, what changed --- in the first version of this board there were still a few issues. the changes from v1 to v2 are as follows: - fix hole spacing. in v1 the holes were barely aligned enough to work without adding wires everywhere, in v2 those should be much better - shorten the pcb. this avoids having the pcb intersect with the lower case of the 3ds, so v1 users have to cut a larger hole into their case - use 0603 resistors instead of 0402 - add some silkscreen - one of the castellated holes is no longer electrically isolated the first version is not available anywhere due to it being obsoleted by v2. ok what's next? --- - [x] design and order v1 - [x] test v1 on actual hardware - [x] learn from it and find improvements - [ ] write blog post and link here - [x] design v2 - [ ] test v2 on actual hardware
