3D localization

The system

The localization system at hand consists of at least 4 "anchors" and a "tag".
Each device communicates and ranges with each other through an UWB (Ultra Wide Band) radio.

The anchors are made up of:

# a cortex-m0 processor from ST (STM32f072)
* an UWB device (DWM1000)
* a pressure sensor (LPS25H)
* a 3.3v low noise LDO regulator (MIC5209)
* a single-cell LIPO charger (MCP73831)

The tags are made up of:

* a cortex-m3 processor from ST (STM32f103)
* an UWB device (DWM1000)
* a pressure sensor (LPS25H)
* a high precision IMU (MPU-9250)
* a 3.3v low noise LDO regulator (MIC5209)
* a single-cell LIPO charger (MCP73831)
