1.1 Hardware requirements
The
X-NUCLEO-IDB04A1
is an expansion board for use with STM32 Nucleo boards (please
refer to UM1724 on www.st.com for further information). To function correctly, the STM32
Nucleo board must be connected to the X-NUCLEO-IDB04A1 board as shown in Figure 2
below.
Figure 2. X-NUCLEO-IDB04A1 plugged to STM32 Nucleo
board
The interconnection between the STM32 Nucleo and the X-NUCLEO-IDB04A1 has been
designed to permit the use of any STM32 Nucleo board, although the optimal combination is
obtained using the NUCLEO-L152RE or NUCLEO-L053R8 hosting the ultra-low power
STM32.

1.2 System requirements
Using the Nucleo boards with the X-NUCLEO-IDB04A1 expansion board requires the
following software and hardware:
a Windows PC (XP, Vista, 7, 8) to install the software package
a USB type A to Mini-B USB cable to connect the Nucleo to the PC
Installation of the board firmware package (order code: X-CUBE-BLE1) and the BlueNRG
graphical user interface utility on the user’s PC requires the following:
At least 128 MB of RAM
40 MB of hard disk space available
The X-CUBE-BLE1 firmware and related documentation is available on www.st.com.

2 Hardware description
This section describes the X-NUCLEO-IDB04A1 features and provides information which
could be useful for understanding the board schematics.
2.1 X-NUCLEO-IDB04A1 board
The board allows the user to test the functionality of the BlueNRG processor. It hosts the
innovative BALF-NRG-01D3 balun & harmonic filter and its functionality can be exploited
using the firmware package contained in the X-CUBE-BLE1. It is fundamental to program
the microcontroller on the STM32 Nucleo board. Please refer to user manuals UM1724 and
UM1725, available on www.st.com.
The BlueNRG processor and the STM32 Nucleo board are connected through connectors
CN5, CN6, CN8 and CN9 (see Table 1 for details). The pins indicated with an asterisk (*)
represent an alternative pin for that specific function, i.e. SPI_IRQ could be moved from
CN8.1 to CN5.2.

The board also includes:
– a high frequency 16 MHz crystal
– a low frequency 32 kHz crystal for lowest power consumption
– a BALF-NRG-01D3 balun & harmonic filter
– an EEPROM M95640-RMN6P to store the board parameters
Not mounted:
– a JTAG connector to program the BlueNRG processor
– an SMA connector for the external antenna
2.1.1 Current measurements
To monitor the power consumption of entire BlueNRG X-NUCLEO-IDB04A1 board, jumper
U5 can be used, inserting an ammeter probe between pins 1 and 2 of the connector. Since
the power consumption of BlueNRG during most of its operating time is very low, an
accurate instrument in the range of few uA may be required.

this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including any interference that may cause undesired
operation.
This device uses, generates and radiated radio frequency energy. The radio frequency
energy produced by this device is well below the maximum exposure allows by Federal
Communications Commission (FCC).
The X-NUCLEO-IDB04A1 is FCC certified (FCC ID: S9NIDB04A1).
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.
