AMB2300 manual V2.3 3/16 Released: 28.01.2010
1 Brief description
Bluetooth-Modul with UART-interface and
integrated Chip-antenna
Bluetooth Class 2 module
Bluetooth Specification 2.0 compatible
Support of Bluetooth Audio
Integrated profiles: SPP, GAP, SDAP
Supported profiles: DUN, OBEX, HSP etc.
AMBER wireless provides with the AMB2300 a certified, qualified listed Bluetooth-module,
based on LMX9830 from National Semiconductor. This compact and inexpensive Bluetooth-
module is qualified for a serial data or audio transmission.
The module has an integrated chip-antenna and can be placed into a circuit like a SMD-part.
AMB2300 comes with an integrated firmware with the complete Bluetooth Stack (Bluetooth 2.0).
A Point-to-Point connection and a Point-to-Multipoint (Piconet) connection are supported by the
firmware. Up to seven active links (Piconet) and one SCO-link (Audio) is possible.
The module can be integrated easily in a system. According to the application and the settings
the AMB2300 can work as a stand-alone-slave-module e.g. as a virtual cable replacement in
combination with any other commercial Bluetooth system.
An evaluation kit AMB2300-EV is available.

2.1 Default settings
All parameters are stored inside the internal EEPROM. See [1] and [2]. In the Bluetooth
environmnent, the device announces itself as a BNC4-XXXXXX (Device Name), whereas
XXXXXX has to be replaced by the device’s Bluetooth address.

The signal level is equivalent to the power supply voltage (2.9V to 3.6V) of the AMB2300 and
has to be matched, if the host system is working with a different signal level.

Caution: in contrast to OP4 and OP5, OP3 must not use a pull-up resistor!
OP3, OP4 and OP5 are pulled down in AMB2300, therefore these pins for the low level are not
to be switched at GND. Here an example of circuit:

3Not connected if not used
4In as-delivered condition the antenna connection is internally not connected

Figure 2 Circuit suggestion
2.2.3 UART interface RX_BT, TX_BT, RTS#_BT and CTS#_BT
The interface serves for communication with the AMB2300. Hardware handshake is used
(RTS/CTS). If this should not be supported by the host system, RTS#_BT and CTS#_BT must
be short circuit or CTS#_BT put on Low levels. This can lead however to data loss due to
overrun! We recommended therefore urgently to use handshake.

2.3 Dimension
AMB2300 has 1mm x 2mm soldering pads with a grid of 2mm to be soldered direct on a
motherboard.
Figure 4 Dimensions
3 Hardware integration
3.1 Layout recommendation
To achieve the maximum of range no metal (ground, strip line, components, etc..) has to be
near the antenna, as shown hatched in the following figure. The antenna should have a

AMB2300 manual V2.3 8/16 Released: 28.01.2010
distance of 8mm to any ground, strip line or component. Most suitable is to place the antenna at
the margin of the motherboard.
Figure 5 Antenna layout
Caution: The AMB2300 is not isolated on the bottom side, so even if there are
normally no short circuit problems because of the solder resist, an isolation should
be placed between AMB2300 and motherboard in case of any copper on the top side
of the motherboard underneath the AMB2300.
3.2 Power supply
For a reliable operation of the module, the power supply has to be provided with a slew rate
over 3V per 500 microseconds. Take care of having no voltage on any pin until the power
supply is turned on properly (Tip: Pay attention to remaining charges of smoothing capacitors).
3.3 Soldering & Reflow
On demand there are taped–automatic assembly –and vacuum sealed –reflow
solderable –components available.
The temperature curve depends on the motherboard its character, like the number and
conditioning of parts, etc. Please ask your manufactor.
Depending on the limit values of the components following limits are not allowed to
excess
o260°C max. 40s (LMX)

AMB2300 manual V2.3 9/16 Released: 28.01.2010
o250°C max. 20s (Chip-antenna)
o200°C max. 120s (Chip-antenna)
The following drawing shows the example of the temperature curve of a 31cm² PCB assembled
on one side.
Figure 6 Example of a temperature curve
Caution: Soldering profile has to be adapted corresponding to the conditions on the
motherboard.

3.4 Recommendation for footprint

3.5 External antenna
The AMB2300 can be optionaly operated with an external antenna. In addition the red marked
condenser (100pF 0603) must, as are changed above shown in its position. The lateral antenna
connection is available then for a coaxial cable or a wire antenna.
Caution: These steps should only be accomplished by persons with good HF
knowledge, since this kind of connection can involve high error potential! By these
measures the warranty and the permission expire!

5 Minimum connection to run the AMB2300
In order to realize a radio transmission, the following connections of the AMB2300 have to be
wired:
VCC, GND Power supply
RX, TX UART data
RTS, CTS UART handshake; if does not need: short RTS and CTS or contact CTS at GND
(without flow control it can come to overrun and lost data)
OP3 High (connect to VCC)
OP4, OP5 Configuration UART, see chapter 2.2.3 (open or 1KΩ pull-up)
All other pins don’t need to be connected.
