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 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).
