5 | P a g e 1 Description The SPBT4.0DP is an easy to use Bluetooth Smart Ready module, compliant with Bluetooth v4.0. The module is among the smallest form factor available which provides a complete RF platform. The SPBT4.0DP enables electronic devices with wireless connectivity, not requiring any RF experience or expertise for integration into the final product. The SPBT4.0DP module, being a certified solution, optimizes the time to market of the final applications. The module is designed for maximum performance in a minimal space including fast speed UART and 8 general purpose I/O lines, several serial interface options, and up to 800 kbps transmission speed with SPP service active, 250kbps with iAP2 service active. Optimized design allows the integration of a complete working Bluetooth modem, including antenna, in the minimum possible size; only an additional external LPO (low power oscillator) is required to enable low power mode capability. The SPBT4.0DP is a surface mount PCB module that provides fully embedded, ready to use Bluetooth wireless technology. The reprogrammable Flash memory contains embedded firmware for serial cable replacement using the Bluetooth SPP profile. Embedded Bluetooth DATA PACKAGE (DP) firmware is a friendly interface, which realizes a simple control for cable replacement. The SPBT4.0DP supporting SPP, iAP2 and Bluetooth Low Energy proprietary Data Exchange profiles, it provides communication with Android, smartphone, and the newest Apple® iOS Bluetooth enabled devices. An Apple authentication IC is required to exchange data with an Apple device or access an Apple device application. The DP FW includes the Bluetooth iAP2 profile capable of recognizing the Apple authentication chip. Customers using the Apple authentication IC must register as developers to become an Apple certified MFI member. License fees may apply, for additional information visit: http://developer.apple.com/programs/which-program/index.html. Certified MFI developers developing electronic accessories that connect to the iPod®, iPhone®, and iPad® gain access to technical documentation, hardware components, technical support and certification logos. Customized firmware for peripheral device interaction, power optimization, security, and other proprietary features may be supported and can be ordered pre-loaded and configured.

Note: - All unused pins should be left floating; do not ground. • All GND pins must be well grounded. • The area around the module should be free of any ground planes, power planes, trace routings, or metal for 6 mm from the module antenna position, in all directions. • Traces should not be routed underneath the module. 6.1 Reflow soldering The SPBT4.0DP is a high temperature strength surface mount Bluetooth® module supplied on an 18 pin, 6-layer PCB. The final assembly recommended reflow profiles are indicated here below. Soldering phase must be executed with care: in order to avoid undesired melting phenomenon, particular attention must be paid to the set-up of the peak temperature. Here following some suggestions for the temperature profile based on the following recommendations. Table 5.

(Part. 15.21) In the case where an OEM seeks Class B (residential) limits for the final product, the following statement must be included in the final product manual: Note: 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. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. In the case where an OEM seeks the lesser category of a Class A digital device for the final product, the following statement must be included in the final product manual: Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his expense.
