Lots of cognates that are common to many languages make it easier. For those of us that lived and worked through the early years, the idea that a single chip device can now connect to Wi-Fi and the Internet is still somewhat akin to magic. This is Heltec's model, which is at 433 MHz and works very well. TTGO LoRa32 SX1276 OLED with Arduino IDE | Random Nerd Tutorials good news: 868MHz (EU) / 915MHz (US) Version now avaliable on Aliexpress--. I translated the manual from Portuguese and will deliver it to you in a PDF file. The boards LoRa support comes in three different variants, operating at 433MHz, 868MHz, and 915MHz depending on region, with an included SMA antenna. Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa use. This is the ideal board to experiment with LoRa projects. Follow my channel on Youtube and my Blog. This is because the antennas are practically glued and extremely close, but as you move them away from each other, you can see that the signal strength decreases, reaching -124dB when you stop to receive the information. Check the LoRa frequencies used in your country. The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions.
