Footnotes

1. Projects from a tutorial are 100% fine! We just want to ask so we can count how people are using tutorials. ↩

2. OnBoard Live is a special version of OnBoard where you can earn more money for designing advanced boards. Check out the #onboard-live channel on our Slack! ↩

3. Hacky Holidays is a limited time PCB event, design a holiday-themed PCB this Winter, and get it shipped. ↩

i just realized hacky-holidays also requires you to submit a wokwi link- https://wokwi.com/projects/418734710495370241

sorry I was going to change my rp2040 to a xiao rp2040 to be safe with the button/usb port but jlc doesn't have it so I'll just stick with this and hope for the best 😭

Hi @CoolCoderSJ, thanks for your Hacky Holidays Submission, just before we review your pull request, we need to ask you a few preliminary questions.

1. Does your PCB require a battery, either a LIR2032 or a CR2032?
2. Is your PCB complex (parts-wise) and or requires Standard Assembly?
3. About how long have you been working with electronics or PCB design?

Lastly, if you haven't done it already, we'll be needing your position and bill of materials (BOM) files. These files can be found in .csv file formats and should be in your /src directory with them named appropriately. Also, please be sure you've supplied all your JLCPCB Part or LCSC Part numbers, if you need help, please message in #hacky-holidays.

[CoolCoderSJ]

1. Yes, an LIR2032
2. It wasn't initially designed to be, but JLCPCB seems to require standard assembly for neopixels now (tl;dr yes)
3. ~a few weeks probably

[Scott170c]

I love the way your PCB looks, just a small detail... the rounded parts of your PCB look low-res. Is this on purpose?

[CoolCoderSJ]

Not really - I had just taken an image of a snowglobe and outlined it
I can try cleaning up the outline if it's going to come out too sharp

[Scott170c]

The outline isn't a big issue, but if you would like it to look better when displaying it I would highly recommend!

Really, really cool submission, but Hacky Holidays requires the use of a XIAO Esp32c3 not an RP2040! If you need the extra performance the RP2040 offers we could make an exception. I'd love to get this shipped!

[CoolCoderSJ]

hi, I was under the impression any MCU is okay! the canvas in the channel says it just has to be under $3 and support economic assembly. Not sure about perf requirements, I think the Xiao should be able to handle 10 neopixels and 2 buttons just the same. I can switch it over!

Yup you're all good! I read that as Xiao RP2040, which had me concerned since JLCPCB stopped selling Xiao components (afaik)!

Hi Shuchir!

I've just sent you your grant for OnBoard. You should have received an invite in your email. There will be instructions on how to use your debit card attached should you need them. Please remember to upload your receipts when you make purchases.

Also, unfortunately, we're unable to offer support with reimbursements for customs fees, including reimbursements using leftover grant funds. Please keep this in mind before you make any purchases. More info in the OnBoard community shipping doc.

I'm looking forward to seeing your PCB be manufactured! Send pictures in the #electronics channel on Slack once you get it! Please don't hesitate to reach out if you have any questions!

Best regards from Hacky Holidays and enjoy Chinese New Year!
P.S. You will also be receiving two LIR2032's.

[CoolCoderSJ]

thank you!
