Butlr Technologies B-WM-01 Wireless Module
Product Description
Butlr wireless module offers a small space envelope and ultra-low power
consumption wireless transmission functionality.
The module comes with 2 orderable models: an onboard ceramic antenna and an
external antenna with an SMA connector. The onboard antenna model is small in
size and can be used for IOT sensing in the large distribution network. The
external antenna model offers flexible connection to a wide range of 2.4GHz
antennas, enabling the product in long-range transmission scenarios.
The design of the wireless module is simple. The module comes with a shield
for signal isolation and protection. The footprint of the module is designed
to be stamp-hole (mouse bit) type, so it’s easy to do both SMT and through-
hole soldering.

RF exposure considerations
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. If the device built into a host as a portable usage,
the additional RF exposure evaluation may be required as specified by§2.1093.
This equipment should be installed and operated with minimum distance 20cm
between the radiator& your body.
Antennas
- The module of B-WM-01-A has one chip antenna and the antenna gain is 1.0dBi.
- The module of B-WM-01-B has one dipole antenna and the antenna gain is 2.0dBi.
- The module of B-WM-01-C has one chip antenna and the antenna gain is 1.7dBi.
Label and compliance information
When the module is installed in the host device, the FCC ID label must be
visible through a window on the final device or it must be visible when an
access panel, door or cover is easily re‐moved. If not, a second label must be
placed on the outside of the final device that contains the following text:
“Contains Transmitter Module FCC ID:2AZPC-B-WM-01” or “Contains FCC
ID:2AZPC-B-WM-01”. The FCC ID can be used only when all FCC ID compliance
requirements are met.
Information on test modes and additional testing requirements
- The modular transmitter has been fully tested by the module grantee on the required number of channels, modulation types, and modes, it should not be necessary for the host installer to re‐test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions).
- The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand‐alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected.
Additional testing, Part 15 Subpart B disclaimer
The final host/module combination need to be evaluated against the FCC Part
15B criteria for unintentional radiators in order to be properly authorized
for operation as a Part15 digital device. The host integrator installing this
module into their product must ensure that the final composite product
complies with the FCC requirements by a technical assessment or evaluation to
the FCC rules, including the transmitter operation and should refer to the
guidance in KDB 996369. For host products with certified modular transmitters,
the frequency range of investigation of the composite system is specified by
rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the
digital device, as shown in Section 15.33(b)(1), whichever is the higher
frequency range of investigation. When testing the host product, all the
transmitters must be operating. The transmitters can be enabled by using
publicly available drivers and turned on, so the transmitters are active. In
certain conditions, it might be appropriate to use a technology-specific call
box (test set) where accessory devices or drivers are not available. When
testing for emissions from the unintentional radiator, the transmitter shall
be placed in the receive mode or idle mode, if possible. If receive mode only
is not possible then, the radio shall be passive (preferred) and/or active
scanning. In these cases, this would need to enable activity on the
communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator
circuitry is enabled. Testing laboratories may need to add attenuation or
filters depending on the signal strength of any active beacons (if applicable)
from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for
further general testing details.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions
- This device may not cause harmful interference, and
- This device must accept any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
