Board Description and Getting started
The X‐NUCLEO‐IDB04A1 is a Bluetooth low energy evaluation board to allow expansion of the
STM32 Nucleo boards. It is compatible with the Arduino UNO R3 connector layout, and is designed
around BlueNRG, a Bluetooth low energy, low power network coprocessor compliant with BTLE
4.0 and the BALF‐NRG‐01D3, an ultra‐miniature balun optimized for ST BlueNRG RFIC, which
integrates matching network and harmonics filter. The X‐NUCLEO‐IDB04A1 interfaces with the
STM32 MCU via SPI pin, and the user can change the default SPI clock, the SPI chip select and SPI
IRQ by changing one resistor on the evaluation board. The excellent performance of BlueNRG and
the best matching between BlueNRG and BALF‐NRG, X‐NUCLEO‐IDB04A1 passed the RF TEST for
Japan Radio Law certification with higher margin above the specification values as well as it is FCC
certified (FCC ID: S9NIDB04A1).

Getting started
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.

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.

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.

Hardware description
UM1765
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.
