LILYGO LoRa32 433Mhz ESP32 Development Board OLED 0.96 Inch SD Card BLE WiFi TTGO Module

I bought a pair of this boards to try out Meshtastic. I had zero experience with these devices, so I just followed the steps in the video bellow. But 1. It is old, the firmware version in it is not longer available. 2. I tried firmware-tbeam-2.2.11.10265aa, but it stuck at the splash screen. 3. Then I tried firmware-tbeam-2.1.23.04bbdc6, but after the setup I got a Critical Fault #6. 4. Tried the other board, same result 5. At this point, I was very close to send the boards back. But I started to wonder that maybe the video is wrong and the boards are OK. 6. Long story short, this device is sometimes referred as "Lilygo Lora", sometimes as "Lilygo TTGO Lora V2.1-1.6" and the right firmware is: firmware-tlora-v2-1-1.6-X.X.X.xxxxxxx.bin In hindsight, I can see that the video was made for a "related product". Anyway, adding a few lines to the description would have saved me (and probably for others too) some time. However, the product works and it does what it supposed to do.

There are all kinds of software for these, apparently, but I use a couple of them to track weather balloons. When the balloons land nearby, I go roaming around and retrieve them. I have five so far. I have two of these receivers: one pairs with the SondeHub website to feed them data and the other is paired with my phone for tracking and locating in the field. A friend designed and printed cases for them. Really cool stuff. Next I'm going to experiment with different antennas for them.

Works great for 433mHz LoRa APRS. I have one as an IGate/Digipeater and one as a Tracker. Other than being a little heavy on battery usage they perform well.

Bought this for use as a Meshtastic node only to find out I had purchased the wrong frequency. It has since been moved to use as part of TinyGS where it's doing very well. We've since purchased a 915Mhz unit for Mesh use and its reach is impressive.

I have used the LilyGo TTGO with good antenna for two fun radio projects - a tiny satellite ground station and a 433 MHz LoRa APRS ground station. 1) TinyGS: After being reflashed with with G4lile0 firmware (Github) the 433 MHz LilyGo TTGO plus a 433 MHz antenna makes a low-cost ground station to receive low-earth orbit LoRa CubeSats. TinyGS ground stations all over the world collect telemetry from various LoRa CubeSat projects. I would highly recommend this build for kids in high school interested in STEM. It may take a bit of assistance. The project does not require a license because it's receive only. 2) iGate: After being reflashed with CA2RXU firmware from github the 433 MHz LilyGo TTGO and a good antenna, the TTGO makes a really nice iGate. An iGate give packets from trackers and comunication devices to be mapped on the internet as well as connect all over the world. This second project requires an Amateur Radio license because it transmits as well as receives. The LilyGo T-Beam is nearly the same board but it adds a GPS chip. Please note that in ITU region 2 (North and South America), there is no ISM band on 433MHz. 433 MHz is an Amateur Radio band. In the US, that's an Amateur Radio Technician license. What I liked: It's the basis for very fun, low cost LoRa-based radio projects. There are many more projects, but these two stand out. The possibilities for hardware expansion and software development are wide open. What I think could be improved: I think the display on the LilyGo TTGO is very small and difficult to read. A larger display would allow more information display area as well as larger fonts for easier reading.

I do not think this board is worth the money ($30) compared to other options out there. The model I received is T3_v1.6.1 20210104 . If you do some research you'll see that it's not recommended for meshtastic, that previous versions of this board had issues with overcharging, and that firmware support is iffy. They should lower the price or bundle in a battery and case if they want to sell at this price point. Buy the T3S3 or a heltecv3 instead. This board just isn't worth the headache when there are so many better options in a similar price range.

I use this for a tinyGS. For better reception build or buy a better antenna. Also works on Meshtastic.

This LoRa board works well. I especially like the on-board on/off mini slide switch that controls whether battery voltage is applied or not, i.e., you don't need an external power switch to keep it from running continuously if a battery is connected. Also nice is the on-board antenna connector which is solidly attached to the board. The quality appears to be good. Nothing on the board is out of alignment, for example. I prefer this board over my Heltec one.

Funciona muito bem. Fácil configurar.

I wanted to learn and play with Metastatic. I picked this up to get started. It was pretty easy to set up and play with. Great for the techno geek who wants to play.

Merci beaucoup pour l'envoi

Use this with RF 433MHz sensors in home assistant , work perfect

Great material and shipment.
