The board section labeled BLUENRG-1 (Figure 2: "STEVAL-IDB007V1 board components"

– region B) includes the following main components:



BlueNRG-1 low power system on chip (in a QFN32 package)



High frequency 16 MHz crystal



Low frequency 32 kHz crystal for the lowest power consumption



Integrated balun which integrates a matching network and harmonics filter



SMA connector

For more details, see Figure 24: "STEVAL-IDB007V1 BlueNRG-1"

Power supply

Green LED DL4 (Figure 2: "STEVAL-IDB007V1 board components"

– region G) signals the

board is being powered, either via:



micro USB connector CN5 (Figure 2: "STEVAL-IDB007V1 board components"

–

region C)



two AAA batteries (region F)



an external DC power supply plus micro USB connector

The following table describes the power supply modes available on the STEVAL-IDB007V1

board and corresponding jumper settings.
