Design Guidelines 6.1 Reference circuit design of the HPYKE24 module. Figure 4. Reference schematic 6.2 Recommended module packaging design dimensions Figure 5. Module package 6.3 PCB Layout and Placement 8 / 14 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. Figure 6. Recommended Layout 6.4 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. 9 / 14 6.5 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. Figure 7. Voltage level-shifting circuit 10 / 14 7. 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. 11 / 14 8. Certifications FCC Statement 1.
