Module：EWN-8258FAT1CA1 12 Reference design 12.1 RF a) Under the antenna and in the two directions indicated by the arrow, avoid covering the ground, routing and placing metal components. It is better to directly hollow out the PCB in this area. Fig 8 Antenna b) It is recommended not to use any components within 30mm of the module antenna area, and the module baseboard should also avoid wiring and covering the ground as much as possible.
Module：EWN-8258FAT1CA1 12.2 Power supply requirement The module power supply voltage is DC+3.3V. The power supply design needs to consider the output current and power interference. The power supply current design needs to reserve 50mA. To avoid the +3.3V power supply from interfering with other circuits on the motherboard, it is recommended to supply to the module using the regulator circuit alone. the recommended DC-DC circuit structure shown in the figure below. A 4.
Module：EWN-8258FAT1CA1 12.3 Motherboard interference avoidance Motherboard interference comes from: high-speed data interface (HDMI), the Operating frequency of main chip, DDR, DC-DC power supply. The method of avoiding interference according to the characteristics of various signals is also different. The main methods of interference avoidance include: 1. keeping away from the source of interference; 2. Adding shields to avoid interference leakage; 3. Reasonable layout to eliminate interference. 12.3.
Module：EWN-8258FAT1CA1 Fig 11 HDIM and USB interference 12.3.2 The main chip interferes with DDR Because the main chips operate at about 800MHz or DDR2 operate at 667MHz, 3x frequency of 800MHz and 4x frequency of 667MHz are near 2.4GHz band. It must to place BT modules and antennas far away from the main chip and DDR. It is strongly recommended that the main chip be isolated from the DDR by a shield. As shown in the figure below.
Module：EWN-8258FAT1CA1 12.4 Recommended secondary reflux temperature curve T he number of reflux shall not exceed 2 times, and the tin feeding height of the half hole of the module shall be no less than 1/4. The lead-free reflux curve requirements of BT module products are shown in figure 13： Fig 13 Furnace temperature curve Note: 1. The maximum furnace temperature of the module is 260℃, don't exceed this temperature. 2. The gold plating thickness of the module pad is 2u".

Module：EWN-8258FAT1CA1 FCC Statement 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.
Module：EWN-8258FAT1CA1 ISED Statement English:This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesired operation of the device. The digital apparatus complies with Canadian CAN ICES‐3 (B)/NMB‐3(B).
Module：EWN-8258FAT1CA1 Important Note: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the ISED authorization is no longer considered valid and the ISED Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate ISED authorization.
