ESP32 LoRa V3 SX1262 Development Board with 0.96 inch OLED Display 240MHz CP2102 863-928 MHz Antenna for Ar duino Meshtastic LoRawan IOT (Upgraded Antenna)

The Meshtastic radio has truly impressed me with its reliable connectivity and user-friendly features, making off-grid communication easier and more accessible than ever. Its compact design and long battery life make it a perfect companion for outdoor adventures, and the intuitive interface allows for quick setup and seamless operation. The open-source platform and active community support add tremendous value, allowing users to customize and enhance their experience. The only drawback is that the screen can be somewhat fragile, so I recommend handling it with care or using a protective case. Overall, it’s a fantastic device for anyone looking to stay connected in remote areas.

Great boards if power use isn't a factor, they work for Meshtastic, meshtastic is still a hot mess. In the past I have used Heltec development boards for IoT Product development projects and they are high quality and suitable for the job (Depending of course on the exact specs and job one is doing). This board has an ESP32-S3 microcontroller and it's great for components which don't particularly need sleep mode and which need LoRa. Other boards are avaialble from Heltec which are far better for node devices which run on batteries and need to use very little energy so that batteries can last years instead of days. I bought this order to try messing around with Meshtastic and it's been an interesting and enjoyable little project. What I can say is that Meshtastic itself is far from being a product but might qualify in it's current state of readiness as a technology in it's very early days of development. It does work, and it does work more or less predictably, but each component has a very long way to go before one might call it a product, and longer still before it coiuld become a consumer product. The software is still buggy and unintuitive, the structures are unclear and often the software has requirements which are poorly documented for the the use of multiple features which are mutually exclusive. If you enjoy poking around and experiementing then it's great fun. Meshtastic can't effectively be set up on it's own without a computer set up to be a development machine with various packages and configurations. Once it's set up it can be used with just a phone app and the dev board and power supply. For these boards I recommend a power pack rather than a rechargable battery. The boards themselves are great, they work very well, they're high quality and the support community is large and long established. In this last project the boards gave no difficulty at all, all of the challenge was with the Meshtastic software.

Works exactly as it should!

I tested the Meshnology N30 ESP32 LoRa Version 3 with OLED display, and it exceeded my expectations. Here’s why I recommend it: ✔ Long-Range Performance: • Transmitted temperature data over 0.9 miles at 14dBm (25mW) (1.4km) real-world testing (with trees/buildings). • In direct line of sight, you can achieve up to 7 miles at 20dBm (100mW), —perfect for remote monitoring. ✔ Easy to Use: • Built-in OLED screen displays real-time data (temperature, humidity, etc.). • USB-C charging and 1100mAh battery (included in some packages) for portability. • With ESP32 Wi-Fi and Bluetooth microcontroller, you can use it for any other applications • Works with Arduino IDE—Robojax’s YouTube tutorial simplifies setup and coding. ✔ Versatile & Secure: • Transmits text, sensor data, or even images via LoRa (SX1262 chip). • Built-in encryption ensures secure communication. • Optional external antenna for extended range. ✔ Test Results: • Receiver battery lasted 24+ hours; transmitter runtime depends on power settings (lower dBm = longer life). • Temperature triggers worked flawlessly (e.g., LED alerts when temps exceed thresholds). • Watch Robojax’s video for full range tests and sample code—it’s a goldmine for beginners! Pro Tips: • For max range, set TX power to 20dBm (100mW) in the code. • Buy the battery/case combo for portable projects. • Use Meshtastic or LoRaWAN for mesh networking. Ideal for: Weather stations, agriculture, industrial IoT, or secure data transmission. A must-buy for LoRa enthusiasts!

Just what I needed. The first one sent only had one of the two antennas pictured. So I returned the first order. The second one sent had everything I needed. It's working great.
