FAQ

What is the actual range of this device?

The range depends on the environment and the antenna used. With a clear line of sight (peak-to-peak), it can exceed 20–30 km. In urban areas, expect a range of between 500 m and 2 km.

Is the device ready to use?

Yes, the Meshtastic firmware is pre-installed. Simply screw on the antenna, turn on the device, and pair it with your smartphone via Bluetooth.

Can I replace the included antenna?

Absolutely. The ThinkNode M1 uses a standard RP-SMA connector, so you can connect a high-gain antenna or a fixed antenna mounted on your roof.

Does the screen display received messages?

Yes, the E-Ink screen lets you read the latest messages, see nearby stations, and check your current GPS location without taking out your phone.

Is it weatherproof?

The ABS casing is sturdy and sealed, but it is not IP67-certified. We recommend protecting it from direct rain or using it in a protective case in extreme conditions.

Why choose the ThinkNode M1?

  • Hardware reliability: Designed by Elecrow with high-quality components (Nordic, Semtech).
  • Ease of use: The physical switch for GPS and the rotary knob make it more intuitive to use than single-button models.
  • Open ecosystem: Hardware fully open to modifications and compatible with Meshtastic community updates.
  • Compact design: Ultra-lightweight and compact, it fits easily in a pocket or clips onto a backpack.
