ID: S9NIDB04A1)
May 2015
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-NRG01D3, an ultra miniature balun optimized for ST
BlueNRG RF IC, which integrates matching
network and harmonics filter. The X-NUCLEOIDB04A1 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 BALFNRG-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).

Any changes or modifications to this equipment not expressly approved by
STMicroelectronics may cause harmful interference and void the user’s authority to operate
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-NUCLEOIDB04A1 is FCC certified (FCC ID: S9NIDB04A1).
