Buy the RAK radio module for the band that is legal where you use it: EU868 in Europe, US915 in the US, others elsewhere. Checking the local rules is your part of the build.

Tools

  • 3D printer
  • Soldering iron with a tip for heat-set inserts
  • Hot air gun
  • Crimping tool for 2.8 mm terminals
  • Multimeter
  • Knife, needle files, M2 and M3 screwdrivers

Build time

Around 2-3 hours, if you have basic soldering and crimping skills and the tools above. A first build with less practice takes longer.

Firmware

The radar firmware is free and open source. The guide walks you through flashing it, and the firmware page always has the latest build.

For your own use

The pack is licensed for personal use. You may build RBakens for yourself. You may not sell printed parts, built units or the files, or share the files.

Safety

RBaken runs on a LiPo battery. Follow the battery maker's instructions, charge with 5 V USB-C only, and never leave a charging device unattended. You build and use it at your own risk.

Rather not build it yourself? Back the limited test batch, or ask for a pre-assembled kit.
