Looking to get into LoRa mesh communication? Meshtastic.org has a thorough introduction and resources to get you started:
Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike ham radio operations.
These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages.

Ditch the smart phone and communicate with your buddy by building this set of walkie talkies! A Feather ESP32-S3 Reverse TFT runs Arduino code that uses the ESP-NOW wireless protocol to send and receive I2S audio packets, up to 10 seconds each. The w.FL antenna adds extra range to communicate at longer distances indoors or outdoors.
