1. Table 11 Step by step guide with Yes and No answers Question Do you wish to make your design compatible with both the cB 0701 01 and the cB 0702 01 module Are you going to integrate the OEM Serial Port Adapter in a metal enclosure Do you wish to use logic level UART mode when communicating with the OEM Serial Port Adapter Are you using a 5V host system Is low power consumption important Do you wish to connect LEDs to the OEM Serial Port Adapter Do you want to detect the status of the module with a controller Do you wish to utilize the restore switch Yes The PCB outlines are larger on the cB 0702 01 module which have to be considered if high components are placed near the module see Chapter 5 There is a little variation in the Voltage power supply and logic levels between the modules and the cB 0702 01 has higher peak current consumption because of higher output power see Section 2 3 The internal antenna models cannot be used Use the OEMSPA13x or OEMSPA33x See Section A 2 1 2 for electrical design See Section A 2 2 Figure 20 for electrical design The power consumption can be reduced by enabling the stop mode see Table 5 The stop mode is controlled with the DSR pin see Section 0 See Section A 2 3 for design examples for connecting the LEDs See Chapter 3 Table 8 for status detection and Section A 2 3 for electrical design See Section A 2 3 3 for electrica2. This connector has a height of 3 0mm 03 option and this has to be considered if components are to be mounted on the motherboard under the OEM Serial Port Adapter board The connector is also available with a height of 6 0mm and 10 0mm 06 and 10 option The AB option is for alignment pin on the bottom side of the connector The connector is available with M2 threaded inserts M option in part no that fit the mounting holes on the board see Section 5 1 3 You may screw the OEM Serial Port Adapter board directly into these inserts If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nut on the backside of the motherboard Another way to mount the module is to use press fit nuts on the motherboard and skip the M2 threads on the connector skip the M option see Section 5 5 for more information about press fit nuts See Figure 13 for more information about the connector and necessary measurements on the motherboard The large mounting holes on the motherboard are designed for press fit nuts and could be smaller if press fit nuts are not used see Section 5 1 3 A La NGI y The lt S wo 8 to Ne t Dimmension for pressfit nut ro 9 FSI 120 lalililililililililalililalilililililigt y gt PCB Outline cB 0701 01 PCB Outline cB 0702 01 Figure 13 Host PCB layout mm for FSI
