Design Guidelines
Reference circuit design of the HPYKE24
Recommended module packaging design dimensions
PCB Layout and Placement
For optimal performance of the WiFi module
Option 1: Place the module aligned to the edge of the application PCB or leave
the antenna area out of the application PCB, as illustrated in the figures
below.
Option 2: Leave the antenna clearance area void of any traces, components, or
copper on all layers of the application PCB if you are going to use the on-
board chip antenna
Note:
Do not place plastic or any other dielectric material in contact with the antenna.
Power Supply
Recommend 3.3V voltage with a current supply above 500mA.
It is suggested to use an LDO for power supply; if a DC-DC design is used, it
is recommended to control the ripple within 30mV.
It is advised to reserve space for a dynamic response capacitor in the DC-DC
power supply circuit to optimize output ripple during large load changes.
It is recommended to add ESD protection devices to the 3.3V power supply
interface
GPIO Pins
The HPYKE24 includes some GPIO ports and it is recommended to connect a 10-100
ohm resistor in series with the I/O port. This can suppress overshoot and
stabilize the voltage levels on both sides. It also helps with EMI and ESD
protection.
For special I/O ports with pull-up or pull-down configurations, refer to the
usage instructions in the specification. This can affect the module’s startup
configuration.
The module’s I/O ports operate at 3.3V. If the main controller’s I/O voltage
level does not match the module, a level-shifting circuit will be needed.
If the I/O ports are directly connected to peripheral interfaces or pins, it
is recommended to reserve space for ESD protection devices near the terminals
on the I/O traces.
Soldering Recommendations
It is recommended that final PCB assembly of the HPYKE24 module follows the
industry standard as identified by the Institute for Printed Circuits (IPC).
Sometimes a PCB must be reflowed multiple times based on the nature of the
design and components used or limitations of the assembly line. During a
single reflow cycle, every component is exposed to and stressed with high
temperature. Exposing parts to high temperature for multiple times can damage
the parts. It is always recommended to avoid more than two reflow cycles of
the parts.
The figure below illustrates the recommended reflow profile that follows IPC /
JEDEC-020, and the peak temperature should not exceed 250℃.

antenna, this antenna is sold with the module.
Notice to OEM integrator
The end user manual shall include all required regulatory information/warning
as shown in this manual. The OEM integrator is responsible for testing their
end product for any additionalcompliance requirements required with this
module installed. If the final product contains circuits of other FCC PART 15
Subparts, the final host product still requires Part 15 Subpart B compliance
testing with the modular transmitter installed. The intended use is generally
not for the general public, it is generally for industry/commercial use. The
connector is within the transmitter enclosure and can only be accessed by
disassembly of the transmitter that is not normally required, the user has no
access to the connector. Installation must be controlled. Installation
requires special training. This device complies with Part 15 of the FCC Rules.
This equipment should be installed and operated with a minimum distance of 20
cm between the radiator and your body.
Operations in the 5.15-5.25GHz band are restricted to indoors usage only.
