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. c) It is strongly recommended that the user place the antenna of the Bluetooth module close to the edge of the backplane as far as possible when laying out the PCB, as shown in the figure below, so as to ensure the good performance of the antenna. Fig 9 Recommended PCB layout Waiting for your suggestion at anytime. 11 E-mailsales@eardatek.com ModuleEWN-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 4.7uF~10uF capacitor is connected in parallel at 3_3VD output to filter out the interference. A bead is connected in series at 3_3VD output. The bead and capacitor must be placed as close to the module as possible. If you need to share +3.3V with other circuits, consider whether the current of the shared power supply is sufficient. Fig 10 Power supply Circuit schematic Waiting for your suggestion at anytime. 12 E-mailsales@eardatek.com 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 ModuleEWN-8258FAT1CA1 include:

1. keeping away from the source of interference;

2. Adding shields to avoid interference leakage;

3. Reasonable layout to eliminate interference. 12.3.1 Interface interference When HDMI uses the 74.2MHz frequency, its 33x frequency is in the 2.4G band of BT, which will seriously interfere with the BT signal. If the HDMI frequency is 148.5MHz, although the 16x frequency is not in the BT band, the isolation of the frequency is not good, and the BT signal will be interfered to some extent. If the distance between the HDMI interface and the BT module on the PCB is less than 5cm, the HDMI output display will interfere with the BT signal, resulting in problems such as BT connection failure and throughput drop. Therefore, keep the location of the BT module away from the HDMI port on the hardware layout to avoid interference. At the same time, if the BT antenna is built-in the motherboard, its placement must also be carefully considered to be far from the interface interference. If the antenna is placed in an incorrect position, even if the module is shielded, the interference signal is coupled through the antenna, which will eventually result in a lower BT throughput. (Note: In addition to interference, the placement of the internal antenna should also evaluate the effect of the metal interface, motherboard, and housing material on the antenna impedance.) Waiting for your suggestion at anytime. 13 E-mailsales@eardatek.com ModuleEWN-8258FAT1CA1 12.3.2 The main chip interferes with DDR Fig 11 HDIM and USB interference 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. Waiting for your suggestion at anytime. 14 E-mailsales@eardatek.com Fig 12 Main chip and DDR interference 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 ModuleEWN-8258FAT1CA1 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".
