LILYGO Meshtastic T-Beam V1.1 18650 Battery Holder

This board is the best of both worlds as it includes both ESP and LoRa communication chips thus it can do IoT and the LoRa would give you the long-range ability for those projects that need to connect/communicate over a longer distance. The LoRa will give you line-of-sight communication between sensors over long distances.
