Introduction
The Spatial OEM development kit allows developers to quickly test and integrate Spatial OEM into
prototypes and low quantity products. It provides the user with access to all of Spatial OEM's
interfaces with a number of convenient connection options.
.1 Kit Contents
The Spatial OEM Development Kit includes:
1. 1x Spatial OEM Module (pre installed)
2. 1x OEM Development Board
3. 1x GNSS Antenna
. 1x Mini USB to USB A cable
5. 1x U.FL to U.FL cable (pre installed)
Attention

3 Quick Start
The Spatial OEM development kit is ready to function straight out of the box using the USB
interface. It is recommended that users familiarise themselves with Spatial OEM through the
Spatial Manager software prior to starting their own integration.
1. If you are using Windows, install Java from http://www.java.com.
2. Download Spatial Manager from the Advanced Navigation website.
3. Open Spatial Manager by double clicking on it. If this does not work, right click and choose
open with → Java
. Screw the GNSS antenna onto the board connector finger tight and place the antenna in an
area with a view of the sky.
5. Plug one end of the USB cable into the development board and the other end into your
computer.
6. Click connect in Spatial Manager. If the connection indicator does not turn green,
disconnect and try selecting another serial port.
3.1 Troubleshooting
If the serial port does not show up when the OEM development board is plugged in, the system
may require drivers. These are available from http://www.ftdichip.com/Drivers/VCP.htm.

4 OEM Development Board Overview
The OEM development board is a configurable PCB that provides developers with easy access to
all of the features of the Spatial OEM module through a number of different interfaces. Illustration 1
shows an image of the OEM development board.
Illustration 1: Labelled OEM development board

Spatial OEM Development Kit Manual
Page 6 of 20
Version 3.0
4.1 Spatial OEM Module
The Spatial OEM module connects to the development board through a micro 20 pin board to
board connector. Four M1.6 stainless steel screws bolt into precision stand-offs and ensure rigid
mechanical mounting to the development board. All development boards are shipped with a Spatial
OEM already mounted to allow immediate use out of the box. If you wish to remove the Spatial
OEM from the development board please refer to the Spatial OEM Reference Manual for mounting
and removal instructions. Please note that the board to board connector is fragile and the module
should be removed with care.
4. Serial UART to USB Converter
An FTDI FT232R USB to serial UART converter chip is included on board to allow the Spatial OEM
to interface directly to a computer through USB. Two status LEDs indicate the flow of data to and
from the USB port.
USB drivers for all operating systems can be downloaded directly from FTDI's website at
http://www.ftdichip.com/Products/ICs/FT232R.htm.
All development boards are shipped with this interface enabled as standard.
4.3 Dual RS 3 Transceiver
A Linear Technology LTC280 dual channel serial UART to RS232 transceiver is included on the
development board to allow developers to communicate with the Spatial OEM module via RS232.
The LTC280 allows baud rates of up to 1000000 baud.
Channel 1 of the LTC280 is for use with the primary serial port on the Spatial OEM Module and
Channel 2 of the LTC280 is for use with GPIO 3 (RS232 TX 2) and GPIO (RS232 RX 2).
Connection to the RS232 level signals is through a 3x2 2.5 mm header, see Illustration 2. This
header is on the left of the board and allows developers to attach wires or headers as needed.
Please note that by default the LTC280 is disabled. Switch 1 turns it on, please see section 5.1.

Version 3.0
4.4 GPIO Header and Status LEDs
Users have access to 6 multi-purpose GPIO pins from Spatial OEM. These are available on the
7x2 2.5 mm header, see Illustration 3. Four of these pins (GPIO 1- ) are also connected to LEDs
on the development board. When using a GPIO in certain input functions, the LED can cause
interference with the signal. In this situation, the LED's resistor should be removed. When using
the GPIO lines for off board functions it is important to note that these signals are not protected
against static charges, over-voltage or over-current events. Failure to protect the signals may result
in damage to Spatial OEM. Other pins on the GPIO header include a regulated 3.3V supply from
Spatial that can supply up to 50mA, Spatial's reset line and the external voltage input (VEXT).
4.5 RF Connection
Spatial OEM connects to a GNSS antenna through a miniature onboard U.FL connector. Due to
the fragile nature of this connector, a U.FL to SMA adapter is supplied on the development board. It
is recommended to use this adapter during development to prevent damage to the Spatial OEM
U.FL connector.
For applications where the development board is placed inside an enclosure it is recommended

that developers use a U.FL to SMA cable assembly. These assemblies are available from most of
the large electronics distributors.

5 Configuration and Operation
5.1 Configuration Switches
The OEM development board contains a DIP switch array that allows the user to route signals
between the USB to serial converter RS232 converter and GPIO header. The configuration switches
are shown below in Illustration 4 in their default positions. The default position routes Spatial's
primary serial port to the USB to serial converter and has GPIO 3 and GPIO 4 connected only to the
GPIO header. Please see Table 1 for the configuration switch functions.
Switch Default Function
1 Off Power on RS232 transceiver.
When the RS232 transceiver is powered on GPIO 3 and will be connected
to RS232 TX 2 and RS232 RX2 respectively. It will no longer be possible to
use GPIO in a TTL level mode. The primary serial port TX will also be
connected to RS232 TX 1 but the primary serial port RX will only be
connected to RS232 RX 1 if switch 2 is turned on.
2 Off Connect primary serial port RX to RS232 transceiver (RS232 RX 1). Please
note that only one of the switches 2,3 or should be turned on at once to
prevent short circuit.
3 Off Connect primary serial port RX to USB serial converter. Please note that
only one of the switches 2,3 or should be turned on at once to prevent
short circuit.
Off Connect primary serial port RX to GPIO header (UART RX). Please note
that only one of the switches 2,3 or should be turned on at once to prevent
short circuit.

5. Power source
The development board has two power source options; USB power (5V nominal) or an external
power source. By default, the development board is configured to use USB power. The external
power source can be fed into the board through VEXT on either the GPIO header of RS232 header
and can be any voltage between V and 36V. Please refer to the Spatial OEM Reference Manual
for full power supply requirements. The power source is selected by a three way switch, please see
Illustration 8 and Illustration 9.

7. Optional Enclosure
The OEM Development Board can be installed into an optional off the shelf enclosure for more
rugged testing if required. The development board will fit inside a Hammond 1550Z106BK or
1550Z111BK heavy duty, watertight enclosure. These enclosures can be purchased from Digikey,
Mouser, Element 1 and many other electronics distributors.
Please take care to ensure that all signals from the OEM development board that are routed out of
any enclosure design are protected against ESD and other potential electrical hazards that may
damage Spatial OEM.
