Important Hardware Additional Information
STM32 Nucleo with Expansion boards - Hardware Overview (5/8)
1.For F4xx STM32 Nucleo motherboard, there is an hardware conflict between the X-NUCLEO-IKS01A2 expansion board and the X-NUCLEO-CCA02M2 expansion board through the Arduino UNO R3 extension connector. The hardware conflict is onto 5,6 and 7 pin of the CN9 arduido
a)For X-NUCLEO-IKS01A2:
•In the pin 5 (SB27) and 6 (SB26) there are the interrupts INT1 and INT2 for LSM6DSL component (used for the feature hardware)
•In the pin 7 (SB25) there is the interrupt for LPS22HB component
b)For X-NUCLEO-CCA02M2:
•In the pin 5 (SB7) there is the clock for the Microphones
•In the pin 6 (SB15) there is the clock x2 for the Microphones
•In the pin 7 (SB17) there is the connection for the microphone PDM34 (solder bridge open as default)
2.For F4xx STM32 Nucleo motherboard, there is an hardware conflict between the X-NUCLEO-IKS01A3 expansion board and the X-NUCLEO-CCA02M2 expansion board through the Arduino UNO R3 extension connector. The hardware conflict is onto 5,6 and 7 pin of the CN9 arduido
a)For X-NUCLEO-IKS01A3:
•In the pin 5 (SB43) and 6 (SB45) there are the interrupts INT1 and INT2 for LSM6DSL component (used for the feature hardware)
•In the pin 7 (SB47) there is the interrupt for LPS22HB component
b)For X-NUCLEO-CCA02M2:
•In the pin 5 (SB7) there is the clock for the Microphones
•In the pin 6 (SB15) there is the clock x2 for the Microphones
•In the pin 7 (SB17) there is the connection for the microphone PDM34 (solder bridge open as default)
For this reason the hardware features are not available for F4xx STM32 Nucleo motherboard (The related gpio pins is not configured).

3.With L4 STM32 Nucleo motherboard:
a)before to connect the board X-NUCLEO-CCA02M2 with the STM32 L4 Nucleo motherboard through the Morpho connector layout onto X-NUCLEO-CCA02M2 board:
•close the solder bridges SB12, SB16 (red highlight) and open the solder bridges SB7, SB15 and SB17 (green highlight - To enable the signal clock from L4 Nucleo motherboard)
•if additional microphones are plugged in the board, close the solder bridge SB17.
b)before to connect the X-NUCLEO-IKS01A2 expansion board with the X-NUCLEO- CCA02M2 expansion board:
•remove the solder bridge SB25 if additional microphones are plugged onto X- NUCLEO-CCA02M2 board
c)before to connect the X-NUCLEO-IKS01A3 expansion board with the X-NUCLEO- CCA02M2 expansion board:
•remove the solder bridge SB47 if additional microphones are plugged onto X- NUCLEO-CCA02M2 board

STM32 Nucleo with Expansion boards - Hardware Overview (7/8)
BlueNRG-2 library does not work with the stock firmware that is loaded in the BLE module of X-NUCLEO-BNRG2A1 expansion board.
For this reason:
•first of all, it is needed to solder on X-NUCLEO-BNRG2A1, if it is not soldered, a 0 Ohm resistor at R117.
•Then you can use a standard ST-Link V2-1 with 5 jumper wires female-female together with STSW-BNRGFLASHER software tool (currently available only for Windows PC) in order to update the firmware of the BLE module of X-NUCLEO- BNRG2A1.
You need to connect the J12 pins of the X-NUCLEO-BNRG2A1 to the pins of the ST-Link V2-1 as shown in the picture and follow the steps show in the next slide.
In particular we have the following connections:

1.install the ST BlueNRG-1_2 Flasher Utility and open it, then select the SWD tab
2.Erase the flash memory of the BlueNRG-2 chip
3.Download the Link Layer Only firmware for the BLE module from the following link DTM_LLOnly.bin
4.Load the Link Layer Only firmware in the ST BlueNRG-1_2 Flasher Utility and then press the "Flash" button
5.If you need to restore the stock firmware of the BLE module of X-NUCLEO-BNRG2A1, you can repeat the procedure using this firmware image DTM_Full.bin
6.If you should find some issues during the update process, you can try to repeat the procedure closing the J15 jumper on the X-NUCLEO-BNRG2A1 expansion board.
