Description
Microchip’s RN4020 Bluetooth Low Energy Module pro-
vides a highly integrated solution for delivering low-power
Bluetooth 4.1 solutions. The advanced command inter-
face offers rapid time to market. The RN4020 module
complies with Bluetooth specification version 4.1. The
module integrates RF, a baseband controller, and a com-
mand API processor, making it a complete Bluetooth Low
Energy solution. The RN4020 can be used with ultra-low
cost microcontroller for intelligent Bluetooth Low Energy
applications. For simple sensor applications, the RN4020
internal scripting capabilities enable basic functions to be
implemented without the need for external host MCU or
software development tools.

4.0 PHYSICAL DIMENSIONS
Figure 4-1 shows the physical dimensions for RN4020
module. Figure 4-2 illustrates the recommended PCB
layout. It is recommended that when laying out the
carrier board for the RN4020 module, the areas under
the antenna, RF test point (semi-circular pad), and
shielding connections do not contain surface traces,
ground planes, or exposed vias.
Figure 4-3 specifies the recommended mounting
details. For optimal radio performance, it is recom-
mended that the antenna end of the RN4020 module
protrudes at least 31 mm beyond any metal enclosure.
Figure 4-4 shows an example of good and acceptable
positioning of the RN4020 on the host PCB.

8.1.2 RF EXPOSURE
All transmitters regulated by FCC must comply with RF
exposure requirements. KDB 447498 General RF
Exposure Guidance provides guidance in determining
whether proposed or existing transmitting facilities,
operations or devices comply with limits for human
exposure to Radio Frequency (RF) fields adopted by
the Federal Communications Commission (FCC).
This module is approved for installation into mobile
and/or portable host platforms and must not be co-
located or operating in conjunction with any other
antenna or transmitter except in accordance with FCC
multitransmitter guidelines. End users must be pro-
vided with transmitter operating conditions for satisfy-
ing RF Exposure compliance.
8.1.3 HELPFUL WEB SITES

oratory Division Knowledge Database (KDB):

8.2 Canada
The RN4020 module has been certified for use in Can-
ada under Industry Canada (IC) Radio Standards
Specification (RSS) RSS-210 and RSSGen. Modular
approval permits the installation of a module in a host
device without the need to recertify the device.
8.2.1
LABELING AND USER
INFORMATION REQUIREMENTS
Labeling Requirements for the Host Device (from Sec-
tion 3.2.1, RSS-Gen, Issue 3, December 2010): The
host device shall be properly labeled to identify the
module within the host device.
The Industry Canada certification label of a module
shall be clearly visible at all times when installed in the
host device, otherwise the host device must be labeled
to display the Industry Canada certification number of
the module, preceded by the words “Contains transmit-
ter module”, or the word “Contains”, or similar wording
expressing the same meaning, as follows:
Contains transmitter module IC: 6514A-RN4020
User Manual Notice for License-Exempt Radio Appara-
tus (from Section 7.1.3 RSS-Gen, Issue 3, December
2010): User manuals for license-exempt radio appara-
tus shall contain the following or equivalent notice in a
conspicuous location in the user manual or alterna-
tively on the device or both:
This device complies with Industry Canada license-
exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not
cause interference, and (2) this device must accept
any interference, including interference that may
cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Indus-
trie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux con-
ditions suivantes: (1) l'appareil ne doit pas produire
de brouillage, et (2) l'utilisateur de l'appareil doit
accepter tout brouillage radioélectrique subi, même
si le brouillage est susceptible d'en compromettre le
fonctionnement.
Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010): User manuals for transmit-
ters shall display the following notice in a conspicuous
location:
Under Industry Canada regulations, this radio trans-
mitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the trans-
mitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotrop-
ically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
Conformément à la réglementation d'Industrie Can-
ada, le présent émetteur radio peut fonctionner avec
une antenne d'un type et d'un gain maximal (ou
inférieur) approuvé pour l'émetteur par Industrie Can-
ada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il
faut choisir le type d'antenne et son gain de sorte
que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à
l'établissement d'une communication satisfaisante.
The above notice may be affixed to the device instead
of displayed in the user manual.
8.2.2 RF EXPOSURE
All transmitters regulated by IC must comply with RF
exposure requirements listed in RSS-102 - Radio Fre-
quency (RF) Exposure Compliance of Radiocommuni-
cation Apparatus (All Frequency Bands).
This module is approved for installation into mobile
and/or portable host platforms and must not be co-
located or operating in conjunction with any other
antenna or transmitter except in accordance with
Industry Canada's multi-transmitter guidelines. End
users must be provided with transmitter operating con-
ditions for satisfying RF Exposure compliance.
