are you able to do soldering to put the coin cell on the back

## Seve — 2026-08-11T20:47:18.019000+00:00

otherwise we have to pay for two sided assembly which is fine but it is pretty simple to solder if you do do it

## Seve — 2026-08-11T20:47:31.422000+00:00

or you could do all the soldering for this board b/c it's quite simple to put together i think

## Seve — 2026-08-11T20:47:45.692000+00:00

looks pretty good, i like the speaker symbol

## Seve — 2026-08-11T20:48:02.983000+00:00

i would say the schematic buttons part could be made much simpler by putting the resistor and button inline

## mohan-bee — 2026-08-12T02:57:52.480000+00:00

How do you program this ? if you are going to use a external attiny programmer then you don't have to assemble , also I see a cap in bottom .. keep that in top itself , for the coin cell holder yea you can easily solder .. if you can't some shops do that ig.

## Seve — 2026-08-12T03:02:30.844000+00:00

yea you need some kind of way to program e.g. test points, i think via swd

## Seve — 2026-08-12T03:02:33.987000+00:00

add a jst port

## Seve — 2026-08-12T03:02:43.681000+00:00

then we can easily do it in lab

## mohan-bee — 2026-08-12T04:42:21.257000+00:00

hey also in the  i see the S1 has 4 pins but sch rep as 2 pin switch take look.

## Seve — 2026-08-12T05:26:50.941000+00:00

yea cuz two are internally connected

## ! Rushabh | Linux Shill — 2026-08-12T14:34:58.214000+00:00

Yeah, I can do it

## Seve — 2026-08-12T16:54:56.173000+00:00

noise

## Seve — 2026-08-12T16:54:59.072000+00:00

*noice

## Seve — 2026-08-12T16:55:11.354000+00:00

so maybe mark that coin cell as doNotPlace and save us from two sided assembly costs

## Seve — 2026-08-12T16:55:20.828000+00:00

you can also check out the cost of both options and lmk

## ! Rushabh | Linux Shill — 2026-08-12T20:01:29.846000+00:00

Actually, I’ve never ordered a PCB before, so I’m not really sure how the ordering process works or how to check the cost. I tried using JLCPCB, but it only shows a $2 + shipping special offer for my first order, so I can’t see what the regular price would be.

<@757706909351411845>

## Seve — 2026-08-12T20:08:25.334000+00:00

yea you have to go all the way to checkout, make sure to select that you want the top side assembled

## Seve — 2026-08-12T20:08:35.283000+00:00

<@398467566588264449> can help you as well, we should have a video tutorial at some point

## mohan-bee — 2026-08-13T02:55:17.185000+00:00

Hye can we order together <@452450065941004289>

## mohan-bee — 2026-08-13T02:55:31.692000+00:00

I will help you through

## mohan-bee — 2026-08-13T03:07:04.742000+00:00

maybe will also cutout the delhivery and import duty tax !

## mohan-bee — 2026-08-13T03:07:17.215000+00:00

which alone gets upto $50

## mohan-bee — 2026-08-13T03:21:35.762000+00:00

<@757706909351411845> wdyt ?

## Seve — 2026-08-13T03:22:43.157000+00:00

🤷 i would just order separately to get it to your house etc haha

## mohan-bee — 2026-08-13T03:23:48.350000+00:00

but that will like blow up to $100 just for delivery and import tax!! For both . maybee after received here we will deliver through local providers

## Seve — 2026-08-13T03:28:31.596000+00:00

Its not a huge deal, i want people to work with jlcpcb support

## mohan-bee — 2026-08-13T09:53:37.400000+00:00

<@452450065941004289>  keep your via 0.3mm 

minViaHoleDiameter="0.3mm"
      minViaPadDiameter="0.45mm"

## ! Rushabh | Linux Shill — 2026-08-13T11:05:36.985000+00:00

done

## ! Rushabh | Linux Shill — 2026-08-18T19:10:09.705000+00:00

i was wondering if we could order this

## Seve — 2026-08-18T19:16:10.041000+00:00

go for it

## Seve — 2026-08-18T19:16:14.642000+00:00

you're going to need a programmer tho

## Seve — 2026-08-18T19:16:29.725000+00:00

make sure you understand the programming procedure and have an SWD breakout maybe with a JST connector

## mohan-bee — 2026-08-18T19:25:18.243000+00:00

maybe you can assemble 2 boards ?

## mohan-bee — 2026-08-18T19:25:55.456000+00:00

is that switch ?

## ! Rushabh | Linux Shill — 2026-08-18T19:26:01.060000+00:00

yes

## mohan-bee — 2026-08-18T19:26:58.973000+00:00

ig this has lot of stock , https://jlcpcb.com/partdetail/C49023765

## ! Rushabh | Linux Shill — 2026-08-18T19:27:46.860000+00:00

not this, the keyboard one

## mohan-bee — 2026-08-18T19:30:09.510000+00:00

maybe this works https://jlcpcb.com/partdetail/HanElectricity-CPG151101D13/C49234235

## mohan-bee — 2026-08-18T19:31:36.605000+00:00

this footprint is different maybe you need to tweak your design too for this

## ! Rushabh | Linux Shill — 2026-08-18T19:32:38.261000+00:00

ATTINY cna be programmed with an UNO

## ! Rushabh | Linux Shill — 2026-08-18T19:32:45.868000+00:00

i already have an UNO

## Seve — 2026-08-18T19:51:39.557000+00:00

yea but do you have something exposed so that you can connect to the attiny
