Getting Started with Meshtastic (915MHz, US)

Meshtastic is a mesh networking project that utilizes affordable, long-range, and low-power radio hardware to create ad-hoc mesh networks. This guide will help you set up a Meshtastic node and join the network.

Hardware Requirements

  • Meshtastic-compatible device: Popular vendors include RAKWireless, Heltec, and SenseCap. There are several other ESP32 boards with LoRa radios that are compatible as well.
  • Antenna: An antenna with 903MHz minimum and 928MHz maximum frequency range. Typically, best performance is achieved with a 3dBi gain. For detailed information on all antennas and their usage, refer to Meshtastic antenna reports.
  • USB-C PD 15V 20W: Power adaptor and USB-C to USB-C cable.

Important Note

Never power on your Meshtastic device without an antenna connected. This could permanently damage the radio.
