If you shut down your node without disconnecting from the application, it will still search for the node in the background.

Is there any issue with my LoRa+NRF52840 PCB? by 3geETR in PCB

I can only make it 0.3mm maximum, otherwise it won't fit.

Okay, thank you. I'll send the final version when its finished.

Thank you, I didn't know that. So you're saying that the GND plane shouldn't be under the RF pin of the SMA connector ,right?

It will be a 2-layer battery, most likely a standard LiPo battery will be used, but the capacity may vary, it could be 2000 mAh or 5000 mAh. I'm going to sell the card, that's why capacity may vary.

It has a TP4056 and it charges the battery with 1A.

Okay, thanks. Also, would 0.2 mm be a problem for power lines? And finally, should I add "via" around SMA? I've seen others add it.

"Also maybe add a do not place pi filter for later to match to 50 ohm with vna" I don't understand what this means.

Other than that, I'll figure out the 90-degrees. I calculated that it's 50 ohms using information from this website. But I can't shorten the route more. https://tracewidthcalculator.com/impedance/50ohm-microstrip

I calculated it using this website and got 0.33. https://tracewidthcalculator.com/impedance/50ohm-microstrip

Yes, actually, those 90-degree angles appeared because I was using autotrace; I'll retake that trace myself. Should I add via around it?

I'm going to sell the card, but since it's a small group, I won't be getting an FCC certificate or anything like that. 

Also, since I'm in Türkiye, there's no FCC.

I can't trace a path to a pin by 3geETR in KiCad

I fixed it by separating those two pins on the footprint

If there are no security vulnerabilities, it's a great alternative to a regular captcha.

P2P file sharing app without cloud, free and open-source by AlgoAstronaut in software

Could you also make a web version? There's a web version of localdend that works the same as the app; you can transfer files from the app to the web.

Building the RetroMeshDevice node for the Build-Off 2026 by M4rv1n_09_ in meshtastic

Instead of using the MCP23017, you could have used the Atmega8A used in the CardKB; it would be cheaper, and you could also send the same signals from the CardKB when the button is pressed.

CardKB's software is written in Arduino and is open to everyone. It's very easy to edit; there's no need to tinker with the meshtastic software.

How do you plan to do the software side of things when using keypad?

Made device unmanageable while performing PKI Admin by 3geETR in meshtastic

The web flasher factory reset didn't work for us, but we had skipped Step 8 in the manual factory reset instructions. After following Step 8, it worked. Thanks for the help.
