LILYGO LoRa32 433Mhz ESP32 TTGO Development Board

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.

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.

Llegó en perfecto estado. Todo bien funcionando 24/7 para TinyGS

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!

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

My first one of these had a bad display. Yet was functional. So dropping a star. Since have bought two more and they work well. Also will work as Meshtastic radios.

Bought this to sniff a Watchman oil tank monitor and feed data into home assistant. It works but the software and configuration takes some working out, more so if not a full on software engineer, got there in the end.

Funciona muito bem. Fácil configurar.

Order delivered during the estimated timeline. I used the transparent plastic housing which came with the board as a case for the board. Besides the 2 holes needed for the microUSB cable and the antenna, I drilled some holes for air ventilation. I flashed the board with OpenMQTTGateway so that I can pick up my 433 MHz devices and integrate them into my HomeAssistant. Flashing and integration into HA went straight forward, so I run it it for couple of hours to identify my own 433 MHz sensors. I let it run for couple of days, though the board memory got flooded and the board go unresponsive sometime afer 24-36 hours and it needed restart. After digging around for some solutions, I ended up with two useful solutions: disabling the decoding of unused protocols and turning off discovery caching. You can do this by sending the coresponding commands using MQTT Explorer. Google AI was quite usefull in recommending the proper commands to run. In HomeAssistant I am monitoring the CPU temperature and the minmemory board parameters and I implemented also two automations which should send notifications to my mobile in case the board minmemory goes below certain value or the temerature goes above certain value. The board is running stable for more than a week now, average CPU temp is ~48 degree Celsius, average free minmemory ~44 kB.

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.

Ho acquistato questa LILYGO LoRa32 433 MHz principalmente per utilizzarla con Meshtastic o per piccoli progetti di ricerca radiosonde e, nel complesso, sono rimasto molto soddisfatto dei risultati (cambiando antenna nella fase successiva). La scheda è compatta ma offre tutto quello che serve per questo tipo di progetto: display OLED da 0,96", ESP32, connettività Wi-Fi e Bluetooth e lettore per scheda SD. Il display, pur essendo piccolo, è molto utile per avere rapidamente sotto controllo le principali informazioni senza dover necessariamente utilizzare lo smartphone. Ha il GPS, quindi è adatto ad esempio per la ricerca di radiosonde. Per quanto riguarda l'utilizzo con Meshtastic, la scheda si è comportata molto bene ed è risultata stabile nell'uso quotidiano. La qualità generale della ricezione e della trasmissione dipende naturalmente da diversi fattori, ma nel mio caso ho ottenuto risultati decisamente migliori dopo aver sostituito l'antenna originale con una di qualità superiore e più adatta all'utilizzo che ne faccio. La differenza rispetto all'antenna fornita di serie è stata evidente soprattutto in termini di affidabilità dei collegamenti. Anche la gestione tramite ESP32 è comoda e rende la scheda molto versatile. L'OLED è un'aggiunta davvero utile, mentre dimensioni e consumi la rendono adatta anche a realizzare un nodo portatile. La costruzione è buona considerando il prezzo e, una volta configurata, la scheda si è dimostrata affidabile. Naturalmente bisogna prestare attenzione alla scelta dell'antenna e a utilizzare componenti compatibili con la frequenza prevista, perché una buona antenna può fare una differenza importante nelle prestazioni radio. Per chi vuole realizzare un nodo Meshtastic a 433 MHz senza spendere cifre elevate, la considero un'ottima scheda. Nel mio caso, con la sostituzione dell'antenna, ho ottenuto prestazioni molto soddisfacenti e una buona stabilità. Un prodotto che ricomprerei senza problemi. Ho usato la sua scatola originale in plastica per creare il mio nodo
