6.5  Micro SD Card Slot 

The SmartRF06EB has a micro SD card slot for connecting external SD/MMC flash devices (flash 
device not included). A connected flash device is available to the mounted EM via a SPI interface, 
giving  it  access  to  extra  flash,  enabling  over-the-air  upgrades  and  more.  Table  8  shows  an 
overview of I/O signals related to the micro SD card slot. 
 
The micro SD card is powered from the 3.3 V power domain (HI_VDD).

6.6  Accelerometer 

The SmartRF06EB is equipped with a BMA250 digital accelerometer from Bosch Sensortech [6]. 
The  accelerometer  is  available  to  the  mounted  EM  via  an  SPI  interface  and  has  two  dedicated 
interrupt lines. The accelerometer is suitable for application development, prototyping and demo 
use. Table 8 shows an overview of I/O signals related to the accelerometer. 
 
The recommended operating condition for the accelerometer is a supply voltage between 1.62 V 
and 3.6 V. The min (max) operating temperature is -40 (+85)
