From the project
Indoor localization based on the DecaWave DW1000.
The PolyPoint system consists of several PCBs centered around TriPoint, the core UWB ranging module.
1. TriPoint: Triangular module which contains all necessary hardware for using the DecaWave DW1000. It has castellated headers so it can be soldered onto a carrier board to add indoor localization functionality to any device.
2. TriTag: Portable carrier board designed to be used as an indoor localization tag. Has TriPoint on one side and a BLE radio on the other.
