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
