XDK uses a Bluetooth low energy controller compliant to Bluetooth specification v4.0.
Key parameters:
Protocol: Bluetooth v4.0 – 2.4GHz
TX Power: -18dBm to +3dBm (programmable)
RX Sensitivity: -80 dBm
Security: AES-128

2.5 SD Card

XDK110 is equipped with a Micro SD card reader that allows the user to store e.g. sensor readout
data or log other events. Due to the processor architecture, SD cards over 32 GB (SD V3
standard) are not supported. Additionally as filesystem are only FAT and FAT32 supported. Please
make sure that the card used supports data transmission via SPI.

2.6 Microcontroller

The XDK110 uses a Cortex M3 MCU of the Silicon Labs' EFM32™ 32-bit microcontroller family. It's
extremely energy efficient and is especially suited for use in low-power and energy sensitive
applications. This allows you to design your applications for efficiency and long battery lifetime
from the very beginning. Details can be found in the
Note: Limitations of energy modes
To make the USB connection fully usable for development purposes, the Energy Modes EM3 and
EM4 of the Gecko MCU are not available on XDK110.
