WaveForm Generator Open IP

Here is a great KickStarter project
An OpenIP waveform generator
https://www.kickstarter.com/projects/nickjohnson/tsunami

Here are the OpenIP files at Github
Here is the PDF schematic
Useful documents have been provided about the Theory of Operation and how to use this device.

MCP4241    is a digital potentiometer
D1               does peak voltage detection
FOX924B      is an oscillator for the microprocessor   16MHz
AD9838
IC6             is an oven stabilized oscillator
CN1           is flash memory


I would like to see an expansion connector that includes
==   SCK , MOSI , MISO ,
==   Any spare I/O pins from the ATMEG processor [ IO13 ,  ]

I really like this board and I want to hack a ARM based micro onto the circuitry ..... possibly using micro-python or pharo smalltalk.


Questions:
What is CN1 ?
What are J3 and J4 for ?
Is there a BOM ?

TOF Time of Flight Sensor VL6180

This is a fascinating sensor.  I have not been able to find out the details of how it works. It appears to use infrared light.  

There is an 80 page datasheet plus some other info.    Here is a 2 page blurb on theory.
There is an evaluation kit.
Sparkfun.com has a kit.   There are some comments at Sparkfun.
Prices are ~ $6 for chip and ~ $20 for eval board
