DESCRIPTION
The Bluegiga APx4 is a small form factor, low
power system-on-module that includes the
latest wireless connectivity standards: 802.11
b/g/n and Bluetooth 4.0. APx4 is based on
Freescale's i.MX28 processor family and runs
an embedded Linux operating system based on
the Yocto ProjectTM. In addition to integrating
the 454MHz ARM9 processor, the wireless
connectivity technologies, Linux operating
system the APx4 also includes with several built
in applications, such as the 802.11
and Bluetooth 4.0 stacks, Continua
v.1.5 compliant IEEE manager and many more.
This combination provides an ideal platform for
designing multi-radio wireless gateways that
enables fast time-to-market and minimum R&D
risks.
The Bluegiga APx4 software can be easily
extended or tailored customizing the Linux
operating system with applications. The
motherboards for the APx4 can be easily
extended to include almost anything from 3G
modems to Ethernet and audio interfaces to
and touch screen displays.
The Bluegiga APx4 is an ideal product for
applications requiring wireless or wired
connectivity technologies and the processing
power of the ARM9 processor, such as health
and fitness gateways, building and home
automation gateways, M2M, point-of-sale and
industrial connectivity.

2 APx4 pin descriptions
The APX4 connector uses a standard DDR1 SO-DIMM connector with 2.5V keying.
Odd numbered pins are located on top layer
Even numbered pins are located on bottom layer
There is a ½ pitch (0.3mm) offset from top layer pins to bottom layer pins.
Note that most receptacles also have 0.3mm offset from odd pins to even pins.
2.1 Receptacle
Suitable receptacles are available from multiple vendors. For example TE Connectivity’s part number
1473005-1, Mouser part number: 571-1473005-1 and Digi-Key’s part number: A99605-ND.
PCB footprint and schematic symbol for the mentioned part number will be available for download
from Techforum in Mentor Graphics’ PADS format.
2.2 Power contacts on the left side
In addition to the 200 pins/finger contacts there are two pairs of plated through holes on the left side of the
module which can be used for powering the module stand-alone (not assembled on any motherboard). The
pitch between the holes is 2.54mm. Leave the holes unconnected if the module is assembled on a
motherboard.
Table 1: Power supply pins
2.3 Debug UART on the right side
On the right side there are four plated through holes for PWM or debug port stand-alone (not assembled on
any motherboard). The vertical distance between the holes is 1.27mm:
