1.2 Block Diagram of the development board

Figure 4: The main sections of the DWM1001 Module Development Board

Figure 4 shows the main sections of the Module Development Board. A brief overview of these sections is given

below with further details given in later sections of this document.

The DWM1001 module is based on Decawave's DW1000 Ultra Wideband (UWB) transceiver IC, which is an

IEEE 802.15.4-2011 UWB implementation. It integrates UWB and Bluetooth antenna, all RF circuitry, Nordic

Semiconductor nRF52832 and motion sensor [1].

The USB connection can provide power to the Module Development Board and also allows for the capability to

flash the DWM1001 module and furthermore to debug software running on the DWM1001 module.

The Power Supply takes its input from USB or from a Battery or from a connected Raspberry Pi. It powers the

module and the other devices on the Module Development Board. It can also charge a connected battery when

powered by USB or the Raspberry Pi.

Two buttons and a number of LEDs are provided for end user applications. A header to interface to the

Raspberry Pi is also provided.
