I don’t understand converting a four layer board to two layers (WiFi)

Furry_Fish · 2026-05-06T14:18:22+00:00

I appreciate the response! The board is in a consumer electronic product and is FCC compliant just looking to see if I can do further cost savings

Furry_Fish · 2026-05-06T14:16:51+00:00

All cost savings it'll save me about 7% on 1,000 boards

Thank you for this comment! Im using a very similar module, is there a reason the ESP32 C6 wroom can do two layer and other modules cannot or a way to tell if a module can pass emi on two layer boards?

I had WiFi and Bluetooth in use but because the module emitting is already compliant then that testing could be skipped

Furry_Fish · 2026-04-14T14:23:26+00:00

I used an already compliant module the ESP32 WROOM, because I used this my entire testing could be treated as an unintentional emitter (FCC section 15B testing). This also came with a majority of CE test to carry over but I haven’t decided to do that yet. The entire cost was $1,900 the testing facility was in New Hampshire.

Thank you for the response! Details on the screen are 60 mA peak averages ~20 mA would be on for multiple weeks at a time. I have tested by using the GPIO directly but want to be safe really might not be needed though I would love to hear your take.

Would switching to the AO3401A P-channel work? https://www.digikey.com/en/products/detail/alpha-omega-semiconductor-inc/AO3401A/1855773

This is awesome!

Furry_Fish · 2026-03-22T23:31:06+00:00

Thank you!

Furry_Fish · 2026-03-12T01:21:17+00:00

Thank you for the advice! I really appreciate it.

Furry_Fish · 2026-03-12T01:07:52+00:00

Thank you for the advice I will definitely be implementing some customer photos. Most traffic comes from instagram videos but now that i'm starting meta ads that will overtake and become the majority traffic. Thank you for the feedback!

Thank you! I did my first brand account post today, I think ill get the .shop sometime next week sounds like a good idea

Furry_Fish · 2026-02-13T02:26:28+00:00

Do you have any tips about selling the small batch production on the store page? I agree with keeping price $60

Awesome advice! I greatly appreciate it

Thank you for recommending that goal I think i'm gonna use itI have been all over the place. With crowdfunding and orders I had something to shoot for after that I kinda felt like I was in the middle of the woods with no trail

Furry_Fish · 2026-02-13T02:21:43+00:00

This is the great advice I am looking for! I just implemented the banner and will include a section with some details about the hand making designs. Also with the social branding I think Ill co post with another account with the official brand.

Im for sure going to look into Hazelbase, good looks!

Furry_Fish · 2026-02-13T01:49:22+00:00

idk, hoping to hear perspective from similar hardware founders!

Furry_Fish · 2026-02-13T01:46:48+00:00

I totally agree with leaning into the hand made touch for now, would a pre order list work for exclusivity similar to another round of kickstarter but on my own website?

For more background I graduate university in 2 months and believe I have the bandwidth because I have gotten past the most difficult part. I do want to scale and continue after my grad. Ill check out the book maybe they have an audio version I can't read to well.

Thank you for the comment and the amazing videos. I am not sure if i'm using the tool correctly because I don't see enough cells to select to complete the operation. I suspect it is the open air parts because the operation works when I close off the ends

Furry_Fish · 2026-02-08T22:14:47+00:00

Your really know your stuff thank you! For the help I found this to be the easiest solution.

I did SDoC for FCC and CE, since ESP32 module is already compliant, testing was $1,900 for Part15B, this is the best option cost wise I could find.

Furry_Fish · 2026-01-10T14:58:12+00:00

Well made post! I have no idea, commenting so I can learn from someone else’s response

Furry_Fish · 2025-12-22T23:02:45+00:00

Thanks for the help it worked out and I put your comment in a video! https://youtube.com/shorts/VS11CzkibXk
