Module：EWN-8258FAT1HA1 11 Reference design 11.1 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 11 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-8258FAT1HA1 11.2 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-8258FAT1HA1 11.3 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. 11.3.
Module：EWN-8258FAT1HA1 Fig 14 HDIM and USB interference 11.3.2 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-8258FAT1HA1 11.4 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 16 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".
