Product Overview
The RSCS DW1000 UWB Module is based on Decawave’s DW1000 Ultra-Wideband (UWB)
transceiver IC and the ST Micro STM32F105 ARM processor. It contains all the hardware required to
implement Ultra-Wideband communications (Two-Way Ranging and TDOA location systems) as a
single shielded unit. It integrates antenna, all RF circuitry, power management, and clock circuitry for
the RF components as well as an ARM processor used to run the Ultra-Wideband application being
employed.

Overview
The RSCS DW1000 UWB Module is an IEEE 802.15.4-2011 UWB implementation. It is comprised of the
Decwave DW1000 UWB transceiver and supporting RF components as well as an ST Micro STM32F105
ARM processor which controls the transceiver behavior. The RSCS DW1000 USB Module enables
RSCS, Inc. to incorporate UWB communications and ranging features into a greater variety of products
in an accelerated and more cost effective way.
Functional Description
The IEEE 802.15.4-2011 UWB compliant transceiver inside the DW1000 is capable of generating and
receiving signals on any of six RF bands from 3.5 GHz to 6.5 GHz. However, it is regulated to the 6489.6
MHz center frequency and 499.2 MHz bandwidth by the Control Interface firmware, for use by the
application for communication and distance measurement purposes. The DW1000 generates/receives a
differential signal (RF_P and RF_N). This is converted to/from single ended by a balun. It is in that form
that it connects to the permanently affixed, FCC 15.203 compliant, antenna.
The DW1000 is controlled by the STM32F105 via the SPI interface. This consists of the traditional SPI
signals (CLK, CSn, MOSI, MISO) plus reset (RSTn) and interrupt (IRQ).
Host Interface
The STM32F105 has two main communication paths to the application Printed Wiring Assembly (PWA).
These are by USART (USART3_TX, USART3_RX) and USB (PA12_DP, PA11_DM). Other available pins
include RSTL (which connects directly to the STM32F105 reset pin).
Programming Interface
There are two means of programming the STM32F105. The basic method is by using the JTAG
interface. The traditional JTAG signals (PA15_JTDI, PA14_JTCK, PA13_JTMS, PB3_JTDO, PB4_JTRST)
as well as the USB lines are available for use.
EEPROM Interface
The application PWA shall have a serial EEPROM. Module pin PB8 (Output) is the clock, and PB9 (BiDir)
is the data. One example of such an EEPROM is the STMicroelectronics M24C64-RMN6TP.
General Purpose Input Output (GPIO)
Most of the other pins have dedicated purposes.
a. ARM_PB7 (input) is sampled after RSTL is negated to select module behavior. If low, the module
shall be an “anchor”; if high, it shall be a tag.
b. ARM_PC12_CK (output) indicates, when high, that the module is transmitting.
c. ARM_RESET_CC (output) indicates, when low, that the DW1000 in the module is being reset.
The application board must not drive this signal. If this signal is driven by the ranging board, the
module will not function properly.
The other GPIO pins (ARM_PB5_IO, ARM_PB6_IO) are unused.

Application Information
Application Board Layout Guidelines
When designing the PCB onto which the RSCS DW1000 UWB Module will be solderered, the proximity
of the Module on-board ceramic monopole antenna to metal and other non-RF transparent materials
needs to be considered carefully. Two suggested placement schemes are shown below.
For best RF performance, ground copper should be flooded in all areas of the apllication board,
except in the areas marked “Keep-Out Area”, where there shold be no metal either side, above or
below (e.g. do not place battery under antenna).
The placement schemes in Figure 2 show an application board with no non-RF transparent material
Keep-Out area, or an application board with the antenna projecting off of the board so that the keep out
area is in free-space. In this second scheme it is still important not to place metal components above or
RSCS DW1000 UWB Module DS
below the antenna in a system implementation. It is also important to note that the ground plane on the
application board affects the Module antenna radiation pattern. In Figure 2 belwo the distance of the
Keep-Out area must be a minimum of 10 mm.

Application Circuit Diagram
A simple application circuit integrating the RSCS DW1000 UWB Module need only power the device
and connect the device to a host controller, see Figure 3.
