Nice T-Beam board for Helium Mapping. NO OLED Display!

For LILYGO® TTGO T-Beam V1.1

The TTGO T-Beam v1.1 is the best all-in-one board for Helium network Mapping.
I use this software build https://github.com/Max-Plastix/tbeam-helium-mapper and it runs perfectly on the T-Beam v1.1

This kit does NOT include the 0.96" OLED display that is commonly included with the LilyGo TTGO T-Beam! You must purchase and solder it on separately.

ESP32, LoRaWAN with antenna, GPS with antenna, Bluetooth, two user buttons and a reset, WiFi, 18650 battery holder & charger, all in one package.
The board has a nice AXP192 power manager on it for power control.
All in all, great value, but you can find them for a similar price with an OLED display included in the kit.

only one of two GPS devices worked properly.

For LILYGO® TTGO T-Beam V1.1 ESP32

I ordered two devices.
Fast delivery and service with tracking information - good.
The first device works as expected - the 2nd device though...

>>>>> message to the seller Lilygo / https://hackaday.io/LILYGO
I spent some time playing around with the LilyGo.
Initially I had some trouble with the GPS which was fixed by the resetGPS sheet. (see attached screen shot)

When I tried to setup the LoRa communication with two devices, I found out that the 2nd device still did not recover the GPS through the reset GPS sheet.

I also flashed back the factory firmware with the esp32 flash tool - the GPS still does not work on the 2nd device.
I would like to replace or refund this 2nd device.
Could it be done together with a new order of two additional devices?

Unfortunately, the seller "Lilygo/https://hackaday.io/LILYGO" has not answered regarding replacement/refund of the 2nd device yet.

Lots of fun!

For LILYGO® TTGO VGA V1.4 Controller

I've only had it for a while and haven't gotten around to building anything with FabGL yet, but it's a great little product, and I've already gotten my money's worth from it from playing around with the various sketches available and investigating VIC-20 development.

If I were to make any improvements to it, it would be to space the connectors further apart to allow USB to PS/2 adaptors to be plugged in for the mouse and keyboard. Also, the default Space Invaders sketch could do with an update as the version preloaded onto it lacks sound, but the most recent version has sound. These are *very* minor quibbles though.

It was a bit late in arriving because it was stuck in Luxembourg for quite some time, but that's not the seller's fault and just something for buyers to be aware of.

For the sketch problem you mentioned, we flashed factory program before shipment for customers to develop by themselves and also shared sample code in product link. If you have any need in use, feel fee to contact us at any time, and we will check and solve it for you :) . As for logistics, usually we provide relatively stable logistics , but please note the time can only be used as a reference in advance , and it needs to be determined according to the actual transportation situation, Have a nice days.

Really impressive device

For LILYGO® T-WATCH-2020 V2 GPS IPS

Most IOT developer boards are bulky or only for porotype purpose. But this watch is really well built and can be used for daily usage.
Well done Lilygo team.

Tested : Touch, TFT, GPS, SDCard, BMA, Power/interrupts, RTC, WiFi. everything is working with no issue.

Observed small heating issue sometimes; not a major problem.

Apart from that, this is the best thing a developer could get for this price.

Response from Lilygo | Jan. 25, 2022

Thank you for your feedback. We are also working hard to develop some convenient products for customers. If you have any suggestions, feel free to contact us at any time. We will also consider it to optimize our products.

fun development board, but documentation is not complete!

For LILYGO T5-4.7 inch E-paper ESP32 V3 version

Instructions aren't very clear. I would like to know how I can convert stock JPEG images and convert them to 4 bit monochrome images. It would also be nice to see every function of the library be better explained with some more examples.

Response from Lilygo | Jan. 25, 2022

Since everyone's project is different, we only provide a simple sample code for customers to develop their own projects. If you have any questions during use, please contact us at any time, we will check and give you solutions . we will also continue to optimize the our sample code, thank you for your feedback.
