The price is way to high to my point of view, especially that is not clear if the TouchScreen LCD is included in that price.
Lets remember that STMDiscovery-F746 is priced at $49 ...

Indeed quite pricey. I think it's clear that the touchscreen won't be included in the $79 price tag since he said that the 'light' version without video ($59) would be cheaper because of excluding the RAM( and not the Display board ).
The dev boards are subsidized to a ridiculous level.
Take for example this board: http://www.digikey.com/product-search/e ... 28-3390-ND
Which has 2x http://www.digikey.com/product-search/e ... 8LTI-LP097

So if you need 2 of those chips you can buy the board for $10 or buy the chips for $30. But Of course they're sill making a profit on the board.

..or little bit more expensive ($78), but better option STMDiscovery-F769.
Anyway it looks like that it is the same display, so we can expect arduino board with this crazy pricetag will be with display as well.

What are the main differences between those F746 and F769 boards except the latest is quite larger ?

@martinayotte more cache, double precision fpu, bigger flash, bigger ram, jpeg codec, one more can bus, and mipi-dsi capability

Yes ! you're right !
I was to lazy to compare both datasheets side-by-side ... :oops:

According to this
http://hackaday.com/2016/05/27/federico ... no-boards/
it seems that the PRIMO has also an STM32F103.
" But on the Primo you get two more controllers: an ESP8266 and an STM32F103."

3 MCUs on board... :roll:
It is a bit difficult for arduino world to handle such complex and probably expensive system.
Connectivity is a good thing but here we have 3 different technologies in separate silicon. ESP for Wifi, Nordic for Bluetooth and STM for USB.
I am waiting more info about it.

Primo looks interesting, but IMHO they should have use the F103RC or F103RE instead of the cut down F103R8

I presume they pre-flash the ESP8266 and nRF52 with firmware and there is an Arduino API to communicate to those devices

Arduino.org seem to be going for the high end of the market, as the cost of a 3 processor board will be far far higher than a Uno


Personally, I would have just produce a board based on a nRF52 as the main processor, as its programmable via GCC (and Nordic produce a SoftDevice (runtime static lib) and gcc compatibe wrapper), and there is already an Arduino core for this (produced by Sandeep Mistry)

Or produce a ESP8266 only board

Or a F103RE only board
