[sdiy] ATSamD4 Breakout Board

[Eric Brombaugh]

The ebay breakout boards that Mikko linked don't have the ST-Link 
programmer on the board while the Nucleo boards from ST do - that means 
all you need to program & debug them is a USB cable, and the ST-Link 
interface also provides a serial port that's handy for interfacing with 
the running system.

The Teensy boards use a Freescale Kinetis MCU that's based on a Cortex 
M4 core. That's considerably more feature-ful than the Coretx M0, with 
more memory, more peripherals and faster clock speed than the low-end 
STM32 and SAMD parts we were discussing, but it's also a fair bit more 
expensive.
