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

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

hubby has purchased 2 now so it must be good! I can't comment on the specifics but if he bought 1, then turned around and bought another It has to be all that! shipping was unusually fast (didn't ship from amazon)too!

Seller was very responsive to a shipping question when Amazon reported item delivered when it wasn’t yet delivered. Seller provided information from post office delivery report that allowed me to track down item which was still located at post office facility, not delivered. Item was delivered after a visit to post office facility. The item was received satisfactorily packaged and protected, and I had it programmed and operational within an hour. I would buy another one from this seller without hesitation.

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.

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.

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.

I flashed this with OpenMQTTGateway and I can control my 433MHz devices with ease.

Ordered two the first failed in a day. Next one would not work. Unable to load software. Was for lora satellite monitoring.

Funciona muito bem. Fácil configurar.

Un module LoRa/ESP32 complet et idéal pour les projets IoT avancés J’ai acheté cette carte LILYGO TTGO LoRa32 (433 MHz) pour un projet IoT basé sur LoRa et ESP32, et elle tient parfaitement ses promesses. Le module est très complet : LoRa, WiFi, Bluetooth, écran OLED, lecteur micro‑SD… tout est intégré sur une seule carte, ce qui simplifie énormément le développement. Ce que j’ai apprécié Le module LoRa fonctionne très bien : portée correcte et communication stable en 433 MHz. L’ESP32 offre suffisamment de puissance pour gérer plusieurs tâches en parallèle (LoRa + WiFi + affichage). L’écran OLED intégré est très pratique pour afficher des informations sans ajouter de composants externes. Le lecteur micro‑SD permet de stocker des logs ou des données de capteurs. L’antenne SMA fournie améliore nettement la portée par rapport aux modules avec antenne PCB. Compatible avec de nombreux projets open‑source (Paxcounter, capteurs LoRa, passerelles simples, etc.). La carte est bien assemblée, propre, et les soudures sont de bonne qualité. Ce que j’ai moins aimé La documentation officielle est assez limitée, il faut souvent se référer aux projets GitHub ou aux forums. La consommation est un peu élevée si on active LoRa + WiFi + OLED en même temps. Pas de boîtier fourni, il faut en imprimer un ou en acheter un séparément. Pour qui c’est idéal Pour les makers et développeurs qui veulent un module LoRa complet et prêt à l’emploi. Pour les projets IoT longue portée (capteurs, compteurs, tracking, monitoring). Pour tester Paxcounter ou d’autres firmwares LoRa déjà existants. Pour ceux qui veulent un ESP32 polyvalent avec écran intégré. Verdict Un excellent module LoRa/ESP32, complet, puissant et très polyvalent. Parfait pour les projets IoT avancés ou pour expérimenter avec LoRa. Très bon rapport qualité‑prix pour une carte aussi équipée.

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

Buon prodotto. Utilizzati per LoRa MeshCom e LoRa APRS da RadioAmatore (433 MHz). Amazon top.

Funktioniert gut... Super Qualität... Schnelle Lieferung.... Gut verpackt... Wird nun als igate für aprs benutzt. DG6BDO
