The SOM provides the basic common set of features with minimal integration efforts for end users.
It contains the following:
•Snapdragon 212 (APQ8009) application processor
•1GB LPDDR3 RAM
•4GB eMMC Flash
•PM8916-1 PMIC for Peripheral LDOs, Boost Regulators, Battery Charging

3.7.2 SOM RF Interfaces for Wi-Fi and Bluetooth Antennas
The Wi-Fi/BT module on the SOM includes the following RF antenna interfaces:
•ANT0: Wi-Fi antenna 1
•ANT1: Wi-Fi antenna 2
•ANT2: Bluetooth antenna
Wi-Fi antennas: The ANT0 port is for one of the two Wi-Fi antennas and ANT1 is for the other Wi-
Fi antenna. Since the Wi-Fi module uses 2x2 MIMO technology and operates in both the 2.4GHz and
5GHz bands, two dual-band antennas are required to be connected to achieve the full performance of
the Wi-Fi interface. By default, both antenna ports are connected to the carrier board PCB antennas
labelled “WLAN ANT1” and “WLAN ANT2” via coaxial cables. Other suitable antennas may be used
by connecting them directly to the Wi-Fi antenna ports on the module with MHF4 coaxial connectors.
Bluetooth antenna: The ANT2 port is for a dedicated Bluetooth antenna. By default, this port is
connected to the carrier board PCB antenna labelled “BT” via a coaxial cable.
The Wi-Fi/BT module is designed with a dedicated Bluetooth antenna port so that the Bluetooth and
Wi-Fi antennas can be physically separated in the end product to provide better isolation between
them. This is done to improve concurrent Wi-Fi and Bluetooth operation. The greater the separation
between antennas, the better the concurrent Wi-Fi – Bluetooth performance will be.
For details on how the Wi-Fi module connects to the on-board PCB antennas on the carrier board,
refer to section Error! Reference source not found..
3.7.1 SOM RF Interface for GNSS Antenna
The SOM includes one U.FL type coaxial connector for the GNSS receiver antenna, with a +2.7v bias
on it to provide power for an active GNSS antenna. By default, this port is connected to the carrier
board PCB antenna labelled “GPS” via a coaxial cable. If desired, a suitable GNSS antenna with a
U.FL connector could be connected directly to the SOM antenna port by carefully removing the carrier
board coaxial cable.
For more information about connecting a GPS antenna to the development kit see section 3.8.15Error!
Reference source not found. below.
Note that the GNSS receiver may not be supported by all SW versions. Please refer to the latest SW
Release Notes document to confirm support.

Note 1: The 12V DC still needs to be plugged in should user needs the following power rails to
power any device on the carrier board:
•MB_VREG_5P0
•MB_VREG_3P3
•MB_VREG_1P8
•VREG_5P0_HDMI
•MB_ELDO_CAM0_DVDD
•MB_ELDO_CAM1_DVDD
•MB_ELDO_CAM1_VCM
Note 2: See Section 3.8.4 and Section 3.8.5 for setting up the development kit to be powered by a
battery
