X-NUCLEO-IDB04A1 STMicroelectronics

X-NUCLEO-IDB04A1 Bluetooth low energy expansion board based on BlueNRG for STM32 Nucleo Data brief X-NUCLEO-IDB04A1 is officially certificated as a BTLE 5mW module for Japan Radio Law TYPE Certification by Japan government RoHS compliant 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. Features The excellent performance of BlueNRG and the BlueNRG low power, low energy Bluetooth best matching between BlueNRG and BALF- network coprocessor NRG-01D3, X-NUCLEO-IDB04A1 passed the RF BALF-NRG-01D3 balun & harmonic filter TEST for Japan Radio Law certification with Free comprehensive development firmware higher margin above the specification values as library and example for BlueNRG, well as it is FCC certified (FCC ID: S9NIDB04A1). compatible with STM32Cube firmware Bluetooth low energy 4.0 master and slave compliant Compatible with STM32 Nucleo boards Equipped with Arduino UNO R3 connector Very low power consumption: 7.3 mA RX and 8.2 mA TX at +0 dBm Maximum transmission power: +8 dBm Excellent receiver sensitivity (-88 dBm) X-NUCLEO-IDB04A1 is FCC certified (FCC ID: S9NIDB04A1) May 2015 DocID026260 Rev 3 1/5 www.st.com For further information contact your local STMicroelectronics sales office Formal Notices Required by the U.S. Federal X-NUCLEO-IDB04A1 Notices Required by the U.S. Federal Communications Commission (FCC) 1 Formal Notices Required by the U.S. Federal Notices Required by the U.S. Federal Communications Commission (FCC) Any changes or modifications to this equipment not expressly approved by STMicroelectronics may cause harmful interference and void the users authority to operate this equipment.
