New Board Comparisons

Boards to consider:

• Beaglebone Black
• Raspberry Pi 2
• ODROID 2
• Edison

Not looking at:

• FPGAs such as MachXO3L due to their complexity and power consumption concerns
• CI20 due to its size
• Gizmo 2 due to cost and power consumption
• Hummingboard due to lack of documentation

High level pro and cos of each:

Beaglebone Black

Pros:

• Familiar, already using one
• Already own

Cons:

• Weakest CPU
• Somewhat poor support

Raspberry Pi 2

Pros:

• 900MHz quad core A7 CPU
• Open GPU
• Best documentation and community support

Cons:

• May be difficult to obtain
• Highest claimed typical power consumption (0.6A)

ODROID C1

Pros:

• 1.5 GHz quad core A5 CPU (probably 40% faster per core than raspi)
• Lower claimed power consumption (hard to believe)
• On board RTC

Cons:

• Possibly higher power consumption (0.5A claimed)
• Concerns with documentation, GPIO pins, and ability to use GPU for FFT

Edison

Pros:

• Built in WiFi
• Lowest power consumption
• Smallest size

Cons:

• Extra complexity
• Lack of proper USB ports
