Don't purchase this device if you're thinking of using it for Meshtastic. Technically it almost works. You can send short messages just fine, but long messages are dropped. The included antenna is useless. It was easy to install and configure on my Pi4 and initial tests with very short messages worked, but it quickly became apparent that this was not appropriate for use on LongFast. It might be ok for other modem presets that have shorter TX time.

This is the board that the Meshtastic Linux-native tutorial video uses, and it is fairly simple to install, configure, and send your first "Hello mesh!". The problems come after that when you try to do anything more.The chip on this board apparently can not send too large of a message without the frequency drifting to the point that the receiving radio is unable to decode the packet. The solution is to drop the Tx power so the chip doesn't heat up as much, but from my testing I've gone down all the way to 3dBm and this board still has issues sending messages with more than 133 characters. Just to be able to exchange public keys with another radio I had to drop the Tx power to 10dBm.If you are just looking to get your feet wet and experiment a little bit, this is probably cheap enough to be an option. If you are expecting to deploy a node for daily use, I would recommend finding a more reliable board.

Works with meshtastic on raspberry pi (I'm personally using zero w, but I'm sure it will work on other models, too). It doesn't have a GPS module, so bare this in mind. It's not a showstopper for me as my node is static and the location is static. Great product for it's price.

Das Teil funktioniert problemlos und sitzt 1a auf dem Pi, die Löcher sitzen exakt übereinander, die Pins sind exakt ausgerichtet, alles passt, lässt sic zu einem sehr schlanken System zusammenstecken. Klasse.

Ce module pour Raspberry Pi est disponible en 4 versions (2 gammes de fréquence différentes, à définir en fonction du pays où on se trouve + avec ou sans GNSS pour avoir le GPS en plus).Il permet de communiquer sur des grandes distances avec un gateway qui se chargera ensuite de communiquer avec un serveur.Pour les grandes distances (ou pour économiser de l'énergie) c'est beaucoup mieux que le wifi/bluetooth.Toutes les documentations sont disponibles sur le site du fabricant, il y a de quoi s'amuser.Je recommande vivement !

Hinweise:Dieser Artikel wurde mir durch das Amazon-Vine Programm kostenlos zur Verfügung gestellt.Dies hat keinen Einfluss auf die Bewertung!Kaufgrund:Stetig anhaltende Experimente mit dem Raspberry Pi.Lieferumfang:- SX1262 Board- IPEX Antennenleitung- Magnetische CB Antenne- Pinheader 2x20- SchraubensetErster Eindruck:In Einzelteilen wird das Set zum selbst Löten verschickt.Qualität:Wie von Waveshare gewohnt, ist die Platine sehr gut hergestellt und verarbeitet.Leider habe ich das Board trotz des wie gewohnt von Waveshare bereitgestellte Wiki nicht zum laufen bekommen können.Entweder habe ich beim Löten etwas beschädigt, obwohl ich jeden Kontakt mehrmals nachgemessen habe oder bei der Installation ist mehrmals etwas schief gegangen.Da die Kommunikation über die SPI und nicht über den i2c Bus stattfindet, bekommt man auch nicht direkt zu beginn eine klare Reaktion ob das Board sich registriert hat.Endbewertung:Dem Board wird keine Batterie mitgeliefert, weshalb man sich um dieses Sondermaß selbst kümmern muss.Für ~25€ bekommt man einen Bausatz welcher (wie evtl. wie bei mir) durch einen fehlerhaften Zusammenbau nicht funktionieren kann.Die Qualität jedoch ist sehr gut und hat keine Beanstandungen.

This is the Waveshare hat that exposes raw SPI access. Yes, that's a pain if you're developing your own solution from scratch. But if you want to use RadioLib or Meshtastic, this is the one you want.

Auf dem Produktbild sind Schalter, LEDs und weitere Bauteile, ein SX1262 und GNSS Chip sowie Antennenanschlüsse für beide zu sehen. Das zugeschickte Produkt hat lediglich den SX1262 und einen Antennenanschluss, der Rest fehlt.

I've been working with LoRa and LoRaWAN for a few years in the Arduino world. I'm no expert, but I've mostly been able to accomplish whatever LoRa solution I needed. When I wanted to add LoRaWAN capability to a Raspberry Pi, I assumed I'd have basically the same experience.Nope. And it's not Waveshare's fault, either. If you want to work with LoRa or LoRaWAN with this device, be prepared to take a deep dive into the protocol and develop your own software solution. I've found only one Python library to help me get a head start (chandrawi/LoRaRF-Python on GitHub). There are a couple of cross-platform C/C++ libraries that you could fill in and compile yourself, and that may be what I need to do. But the gist of it is that if you have a requirement for a quick solution, you're probably better off sticking with Arduino or other embedded platform.The reason for knocking off two stars: the documentation for this module on Waveshare's wiki is junk. I've purchased many items from Waveshare and generally consider them to be reputable, but they missed the mark on this.One of the issues is that the wiki mentions a TXEN and RXEN, but these aren't actually exposed on the pinout. They also provide a link to a datasheet for a RF switch IC, which I guess is what they use to switch the SX1262 between TX and RX modes. Further down, they mention a DIO2 pin, but this isn't exposed on the pinout. But the pinout does show a DIO4, but they never say what it's for. Is this a typo? Is DIO4 actually DIO2?The wiki also goes into great detail with fancy infographics on the LoRaWAN stack and examples of how different devices communicate with each other, but this is all generic -- none of it is specific to how this module can be used as a LoRaWAN node or gateway.The other perturbation: there are no schematics. I could very easily clear up the confusion if I had a set of schematics to look at, but nope.So, the fact that I cannot use this readily is mostly my fault for not doing my homework before making the purchase, and I can't blame Waveshare for not providing a ready-to-use software package (although that would have been nice, and I would have gladly paid 2 or even 3 times more for a module that I could use right away). But their confusing/lacking documentation made the experience worse.If you're an expert software developer and experienced in LoRa or other communication protocols, you'll probably be alright with this, it'll just take some time to develop whatever solution you're after. If you're a tinkerer expecting to plug this in and start sending or receiving messages, you'll be frustrated and disappointed.
