How Would You RoadTest This System on Module (SOM) for Embedded Linux Applications?

I was handed some information on Microchip's new SOM (PN: ATSAMA5D27-SOM1) for embedded Linux applications. The SOM can be used in Microchip's ATSAMA5D27-SOM1-EK1 dev board or place the module onto your application board.

Featuring an ARM-based MPU, the module is a small-single sided PCB, 40mm x 38mm, industrial temperature grade (-40/+85C) and requires a single 3.3V power supply for operation.

Microchip calls is a "ready to go" Linux solution. It's is supplied with in-house Linux support.

Here are the key features:

System-In-Package (SAMA5D27C-D1G-CU) including:

Arm Cortex-A5 processor-based SAMA5D2 MPU
1Gbit DDR2 SDRAM

On-Board Power Management Unit (MIC2800-G1JJYML)

1Kb Serial EEPROM with EUI-48 Node Identity (24AA02E48T-I/OT)

64Mb Serial Quad I/O Flash Memory (SST26VF064BT-104I/MF)

10Base-T/100Base-TX Ethernet PHY (KSZ8081RNAIA)

40 x 38 mm Module, Pitch 0.8mm, solderable by hand

103 I/Os

Up to 7 Tampers

One USB Device, one USB Host and one HSIC Interface

Shutdown and Reset Control Pins

Independent Power Supplies Available for Camera Sensor, for SD Card and for Backup depending on

Voltage Domains

Operational Specifications:

Main operating voltage: 3.3V ± 5%
Temperature range: -40°C to 85°C
Integrated crystals, internal voltage regulators
Multiple interfaces and I/Os for easy application development

So, what are your thoughts about roadtesting this baby? Feel free to offer your comments below.

(Here's a link to the technical manual.)

The roadtest will include only the SOM (ATSAMA5D27-SOM1) or the ATSAMA5D27-SOM1-EK1 dev board?

Looking at the Microchip documentation that board has a great range of peripherals including:
CAN bus
mikroBUS x2
PMOD x1
LCD Interface
Camera Interface

The Linux distro setup for the board is available at this link http://www.at91.com/linux4sam/bin/view/Linux4SAM/Sama5d27Som1EKMainPage#Demo_archives - this cool site also provides other SAM based board Linux distros so well worth a browse !

To answer the Roadtest question - I guess once Linux is setup and running it would be to try and make something fun/novel based on components/modules available to the tester.

I'd be tempted to see if this could be used to setup a cluster of machines and then run a Docker swarm on it. A quick scan through the datasheet shows that the module itself has the Ethernet PHY on it (rather than the evaluation board), so it should be possible. It would mean designing a custom backplane for it though, so perhaps beyond the scope of a road test.

This is an Exciting Module, reminds me of C.H.I.P .

I would love to see where all can the SoM be integrated. It is small enough to integrate into some really interesting Applications, like
Quadcopter (With some AI capabilities) , House hold appliances, IoT Applications, Smart vehicles, etc. The list goes on and on.

I would be hoping E14 gives couple of the SOM (ATSAMA5D27-SOM1) module for user application and/or the ATSAMA5D27-SOM1-EK1 kit for testing . This way there may be some interesting designs also
