1 Getting started
This section describes the hardware requirements for the X-NUCLEO-IDB04A1 evaluation
board.
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 connected 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.

4/13 DocID026346 Rev 3
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 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.
To change the default pin SPI_CLK and SPI_IRQ, the user must disassemble, respectively,
R10 and R12, and assemble R11 and R16.

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 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 microamps may be required.
