Blumod BMD-200 Module for Bluetooth 4.0 LE
The blumod BMD-200 from Rigado is a powerful, highly flexible Bluetooth Smart module based on the
nRF51822 SoC from Nordic Semiconductor. With a ARM® Cortex™ M0 CPU, embedded 2.4GHz transceiver,
and on-module chip antenna, the BMD-200 provides a complete RF solution with no additional RF design,
allowing faster time to market. The BMD-200 provides full use of the nRF51822’s on-chip peripherals,
allowing for a wide range of applications without the need for an external host microcontroller; simplifying
designs and reducing BOM costs. With an internal DC-DC converter and a voltage supply range of 2.1V to 3.6V,
the BMD-200 can be powered directly from a coin cell or two AAA batteries with ultra-low power
consumption.

Clocks
The BMD-200 module requires two clocks, a high frequency clock and a low frequency clock.
The high frequency clock is provided internally by a high-accuracy 16-MHz crystal as required by the nRF51822
for radio operation.
The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock; or
externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption.

Recommended Copper Keepout
The area under and extending out from the antenna portion of the module should be kept clear of copper and
other metal. The module should be placed at the edge or, ideally, at the corner of the PCB with the antenna
edge facing out.

FCC Certification
The BMD-200 module has a certification from the FCC to be used as a modular transmitter. Devices that
include the BMD-200 must state on the label that it “Contains FCC ID: 2AA9B01”.
FCC Statement
This device has been tested and found to comply with part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
Operation is subjected to the following two conditions: (1) This device may no cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired
operation. Note: Modification to this product will void the user’s authority to operate this equipment.
Note: Modification to this product will void the users’ authority to operate this equipment.
FCC Important Notes:
(1) FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter should be installed and operated with a minimum distance of 20
Centimeter between the radiator and your body and must not be co-located or operating in
conjunction with any other antenna or transmitter.
This equipment complies with Part 15 of the FCC Rules. Operation is subject the following two
conditions：
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
BMD-200 V0.1 CONFIDENTIAL Page 9 of 9
The devices must be installed and used in strict accordance with the manufacturer’s instructions as
described in the user documentation that comes with the product. Modular could be only used in
mobile or fix device, and could not be used in any portable device.
Caution!
The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications to this equipment. Such modification could void the user authority to operate the
equipment.
(2) Co-location Warning:
This device and its antenna(s) must not be co-located or operating in conjunction with any other
antenna or transmitter.
(3) OEM integration instructions：
This device is intended only for OEM integrators under the following conditions：
The antenna must be installed such that 20 cm is maintained between the antenna and users, and
the transmitter module may not be co-located with any other transmit or antenna. The module shall
be only used with the integral antenna(s) that has been originally tested and certified with this
module.
As long as 3 conditions above are met, further transmitter test will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirement with this module installed(for example, digital device emission, PC peripheral
requirements, etc.)
(4) OEM integration instructions：
In the event that these conditions cannot be met (for example certain laptop configuration or co-
location with another transmitter), then the FCC authorization for this module in combination with
the host equipment is no longer considered valid and the FCC ID of the module cannot be used on
the final product. In these and circumstance, the OEM integrator will be responsible for re-
evaluating. The end product (including the transmitter) and obtaining a separate FCC authorization.
(5) End product labeling：
This transmitter module is authorization only for use in device where the antenna may be installed
such that 20 cm may be maintained between the antenna and users. The final end product must be
labeled in a visible area with the following：
“Contains Transmitter Module FCC ID: 2AA9B01
(6) Information that must be placed in the end user manual：
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user’s manual of the end product which integrates this
module. The end user manual shall include all required regulatory information/warning as show in
this manual.
