3. Hardware Design
All unused pins should be left floating; do not ground.
All GND pins must be well grounded.
The area around the antenna should be free of any ground planes, power planes, trace routings, or metal
for at least 6.5 mm in all directions.
Traces should not be routed underneath the module.
ANT 2.4G and ANT 5G:RF bi-directional antenna port matched to 50Ω, molex 1461530100.
RF traces must be as short as possible for best RF performance，like below.
RF traces must be routed on the top layer, far away from other high speed signal traces.
Digital traces should not be placed directly under RF trace layers.
All RF traces must have a solid ground plane below.

The WF60 is a surface mount Bluetooth module supplied on a 18 pin, 6-layer PCB. The final assembly
recommended reflow profiles are:
For RoHS/Pb-free applications, Sn96.5/Ag3.0/Cu0.5 solder is recommended.
Maximum peak temperature of 230° - 240°C (below 250°C).
Maximum rise and fall slope after liquidous of < 2°C/second.
Maximum rise and fall slope after liquidous of < 3°C/second.
Maximum time at liquidous of 40 – 80 seconds.

4. Startup behavior
4.1. RESET and PMUEN
A valid reset shall be obtained by maintaining RESET active (low) for at least two cycles of LPO after
VIN is stable within its operating range. There is no constraint on the activation of the other supplies
during this process.
4.2. SDIO and SPI interface
SDIO 5 is the selection pin; the state of this pin is monitored on the rising edge of RESET.
LOW selects SPI
HIGH selects SDIO
5. Regulatory Compliance
Federal Communications Commission statement:
This module has been tested and found to comply with the FCC Part15.
These limits are designed to provide reasonable protection against harmful interference in approved
installations. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular
installation.
This device complies with part 15 of the FCC Rules. Operation is subject to 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.
Modifications or changes to this equipment not expressly approved by Amp’ed RF Technology may
void the user’s authority to operate this equipment.
The modular transmitter must be equipped with either a permanently affixed label or must be
capable of electronically displaying its FCC identification number
(A) Host labeling requirement: Contains FCC ID: X3ZWFMOD10
The module is a limited single module without completed shielding case, CIIPC or new filing shall
be applied for any host equipment using this module, such as provide the completed shielding case
for this module.
(B) If the modular transmitter uses an electronic display of the FCC identification number, the
information must be readily accessible and visible on the modular transmitter or on the device in
which it is installed. If the module is installed inside another device, then the outside of the device
into which the module is installed must display a label referring to the enclosed module. This exterior
label can use wording such as the following: “Contains FCC certified transmitter module(s).”

To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a
separation distance of 20 cm or more should be maintained between the antenna of this device and
persons during operation. To ensure compliance, operation at closer than this distance is not
recommended. The antenna(s) used for this transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
(C) This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to 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 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.
