1 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 RF IC, 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-01D3, 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).

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 3

below.

Figure 3. 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.

To change the default pin SPI_CLK, SPI_IRQ and SPI_CSN the user must disassemble,

respectively,R10, R12 and R15, and assemble R11, R16 and R13.

UM1765 Hardware description

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-RMN6TP 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 µA may be required.
