915MHz ESP32 LoRa V3 Development Board SX1262 0.96 Inch OLED Display WiFi+BLE Lora Kit with LoRa Antenna for Arduino IOT Smart Home (2Sets)

Great LoRa radios. I have enjoyed dealing with DIY malls in general. Great price.

Antenna and fly leads did not come with boards, useless without these!

Great even without using the lora on this device, as an ESP32. Nice built in features, especially the display and charge circuit. Great option to start off with lora. You can easily set up a long range (w/ line of sight) communication (no license required for point to point with just your two devices).

I have been working with ESP-32 boards for awhile. Most of my projects use WiFi or BLE and have their limitations if the WiFi signal is not available or lost.I can think of several useful projects that would benefit using LoRa communications such as battery powered remote sensors. With the ESP32-S3 having such a low power consumption in deep sleep mode, these sensors will not require large battery packs.The boards come preloaded with a test file from Heltec. For more information, drivers and project samples visit the Heltec website. You should be able to plug in a USB-C powerpower cord. In the test code, the unit will check and display if it connected to wifi. It will then display a list of WiFi networks found. Then it will then send a “hello” string via the Lora communications.The display will continue sending the packed indicting the number of time sent and the number received. Along with the send signal level and the received signal level. On the bench with the antennas connected I achieve a perfect 0dB signal. On the bench, the units still should communicate. I had them about 6 feet apart without antenna and -100 Rssi, they were still communicating with no dropped packets. Specs say I still should be able to communicate at -139dB.I then separated the units. Leaving one on my basement workbench and the other all the way out in the garage to simulate my worst signal path. I still was able to connect the 2 units as shown in the pictures.My mind is spinning now thinking of all the possibilities since there are so many things already implemented in to this small package. I may have found a new favorite development board.
