Description

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).

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-NUCLEO-

IDB04A1 is FCC certified (FCC ID: S9NIDB04A1).
