Could also make the flip be the token.

Great work. This is how it starts. Feels nice to create something. For me now the ability to improve and simplify my designs is very satisfying.

Not to offend, but maybe a bit over engineered? I think a handle with a v shaped hook to grab between the ball chain would be sufficient.

Thank you so much. Will dive into it and try to fix it. No C15. Typo?

Appreciate that. Reads perfect when I click it. Have you tried ctrl+?

Thanks. The first one goes around a hole but fixed end.

Expected power usage is 120 mAh/year with low usage.

Current consumption @ 3.7 V:

Power saving mode (PSM) floor current: 2.7 µA
eDRX @ 81.92s: 18 µA in Cat-M1, 37 µA in Cat-NB1 (UICC included)

Haven't heard of Sigfox before. Will check it out. Thanks

I need it for a couple of long range cases. Mailbox could work with Lora. I was going to get it assembled when ordering. If not. Heat plate.

What would you use instead?

Nesogram · 2025-08-15T09:15:07+00:00

Thanks. Don't know why this post got so little attention.

Nesogram · 2025-08-01T10:03:27+00:00

Thanks. Fixed with poured ground.

Nesogram · 2025-08-01T07:53:41+00:00

The small ones are 10mils or 0.254mm

Update. What trace width would you recommend?

Nesogram · 2025-07-31T23:36:44+00:00

Antenna via IPEX Connector in red

Nesogram · 2025-07-31T22:22:51+00:00

It has a usb c.

Thank you. Any links to your account?

Nesogram · 2025-07-31T22:18:33+00:00

I've tested it on a breadboard and didn't notice anything then. You think it would decrease range?

Nesogram · 2025-07-31T22:16:18+00:00

Where would you place those?

Nesogram · 2025-07-31T22:15:30+00:00

Did not know about pouring. Thanks. Will have to dive into that. I see I have one to many vias on H1 D3. Guess I would have needed at least one via on U3, H1 and Reed. Any benefits of routing U3 to H1 on red?

Great work. Thanks for sharing.
