Lilygo T-Echo with Meshtastic

In today’s video, we’re going over the Lilygo -T-Echo. The only current ready to go out of the box Meshtastic device (other than flashing the firmware). But will it become my new go-to device?

A proper cell phone should be your go to. It's 2024.

Antennas is ⅛ or ¼ or ½ or 1 of the bandwidth real width. The 900 Band is around 33cm. ½ is 16, 5cm, ¼ is 8, 25cm and ⅛ is 4, 125cm. Best is full length but a 33cm is to big. A antenna for 915 can also work for 1800MHz and 450MHz. 459x2=918MHz. It is tuned for 915MHz.

Awesome video! 👏 We really appreciate your clear breakdown of the LilyGo T-Echo and how it works with Meshtastic. Thanks for always providing valuable content to our community! #Meshtastic

Got 2 of these last week, immediately upgraded the batteries to 1300mah size, and changed the garbage antennas. Lasts 4 days on a 1300mah.

I wish I understood what you were talking about and how these devices had a realistic real world use. I'm just getting into it and it has a high learning curve.

FINALLY someone using a suitable microcontroller for low-power applications like this! It's never made sense to me why Lilygo and others have stuck with the ESP32 platform for low-power, portable applications given that it doesn't exactly do very well on the power consumption front and is *massively* overkill for the simple task of text messaging.

Just used your link to buy a T-Echo. Love your vids!

Nice. Got mine in the mail today. Can’t wait to test them out in the mountains of Colorado in a couple weeks.

This seems cool, but I’ve watched multiple videos (this channel and others) and still have no idea what a real-world use-case would be for this. For example, if I had a node at my house, could I go out to the store and text back to my home? Can I send this out with my kids and they text me when they are ready to be picked-up? Will the signal strong enough to use in buildings? What’s the range?

These seem like super basic questions to me, yet no one seems to have a video explaining actual usage. What am I missing?

[Dolmdemon]

I really dig your content. I keep coming back to your videos in my efforts to figure out what I want in deploying meshtastic devices. Good work bro.

[HamRadio]

Great video. Link shows sold out for now, so I'll keep watching for them.

Ive been looking toward these as a relay for 'going bush' here in Australia; set up a 'base station' at camp that has internet/mobile data to connect to other people for comms and emergency, and take one with me on long bush walks or hiking out further. Would be a great idea and I have even started talking to Australia's National Parks service about adding LoRa/Meshtastic to 'high points' in places like the Blue Mountains in NSW and walking tracks along the East Coast of Australia

You can snip the tip of the Nb-iot 20cm antenna. About 17 or 18mm takes it to about 915, a little less to tune to 907. Just take a few mm off at a time while measuring on the VNA. Just make sure to replace the rubber tip for each measurement--it matters.

1km - 250km. Depends on environment and set up.

It really good people are working hard to develop mesh network.

[yamez]

Key point over other Lora compatible Meshtastic models is the lower powered screen and battery management efficiently.

I know a lot of those antennas are tuned for HTs where you act as a ground plane. It may be worth while testing come with a small counterpoise. I use thin solid core wire just wrapped around the outside terminal to test this personally. I also wonder how some GMRS antennas do since I think they tune for 462, so 924 shouldnt be awful either. Also put in my order for the TH-D75A at HRO today. Looks like it went up in price over the 74, but I still think its worth.

Hi. Great job and You found my battery extension back cover project. Thanks 😊

[brandonduggan]

You might have a video on this already but I’d like to see your full set up with meshtastic and how you use it

[utvwerxoffroadfabdesign]

So can this be connected to a phone via Bluetooth to integrate ATAK usage as well?
