crystal trace path XIN/XOUT has vias in it

label J2 and J3 pin labels

## Seve — 2026-09-06T19:48:49.557000+00:00

are you on the latest tscircuit, schematic trace solver should be drawing this better

## techmannih — 2026-09-06T19:52:04.565000+00:00

Yep it’s the latest version. There might be an issue with the schematic trace solver right now. I’ll try to fix that as well.

## Seve — 2026-09-06T19:52:19.623000+00:00

yea this is pretty close but the schematic is hard to read still

## Seve — 2026-09-06T19:53:38.912000+00:00

i think we should do some new checks for schematic style to enforce that e.g. decoupling capacitors on the same rail are close together

i'm also annoyed about LEDs and their paired resistors not being close together

ALSO very important but some of the LEDs are backwards and that should really be caught

## techmannih — 2026-09-06T19:55:51.435000+00:00

im fixing them

## techmannih — 2026-09-07T05:47:14.244000+00:00

Understood! For the style check, I'll add a new analyzer in circuit-json-schematic-placement-analysis to enforce that decoupling capacitors on the same rail are grouped together.
And I'll update schematic-trace-solver to stop drawing zigzag alternating traces across parallel decoupling caps and instead give them clean local rail/ground labels.

## techmannih — 2026-09-07T05:48:57.159000+00:00

Does that sound right?

## Seve — 2026-09-07T05:52:24.750000+00:00

yea

## techmannih — 2026-09-11T10:47:40.256000+00:00

fixed all these issue

## techmannih — 2026-09-11T10:47:51.632000+00:00

please take a look

## techmannih — 2026-09-11T10:50:01.929000+00:00

<@809856037376491570> <@398467566588264449> also please take a look

## Rishabh — 2026-09-11T14:53:18.366000+00:00

Don't use two layer assembly, the board seems to have enough space to fit all the components on the single top layer

## techmannih — 2026-09-11T15:00:47.357000+00:00

On it

## techmannih — 2026-09-11T16:32:54.209000+00:00

fixed now all component are on the top layer.

## techmannih — 2026-09-12T03:10:47.994000+00:00

<@398467566588264449> please take a look

## Abse — 2026-09-14T16:12:09.760000+00:00

will take a look sry didnt see it

## Abse — 2026-09-14T16:24:51.889000+00:00

<@1067854999889137715> looks good but do check the cautions in the image first

## Abse — 2026-09-14T16:26:54.009000+00:00

also make sure to use the right via size and to use fabrication notes where polarity is needed

## techmannih — 2026-09-15T20:35:45.304000+00:00

yea 
minViaHoleDiameter={0.2}
minViaPadDiameter={0.45}

## Abse — 2026-09-15T20:54:35.976000+00:00

0.3 !!!

## Abse — 2026-09-15T20:54:39.837000+00:00

<@1067854999889137715>

## techmannih — 2026-09-15T20:57:29.488000+00:00

Nah, last time when I was ordering the board, Rishabh told me the same

## Seve — 2026-09-15T21:02:18.932000+00:00

<@1067854999889137715> 0.3 drill is the minimum to avoid extra charges

## techmannih — 2026-09-16T07:28:48.055000+00:00

updated yea now im using 0.3 drill

## techmannih — 2026-09-30T09:51:31.023000+00:00

<@809856037376491570> <@398467566588264449> now all check shorts issue fixed, is it ready for order

## Rishabh — 2026-09-30T10:00:18.254000+00:00

Add schematic text, with the explanation

## techmannih — 2026-09-30T10:47:41.337000+00:00

DONE
