I have been obliged to help the author that did not understand how a MiniTiouner works, he has just made a copy of the schematic given on Vivadatv forum( Minitiouner and MiniTiounerPro) and has just removed the LNB power supply and others extensions.
So when I read on the documentation that they have "developed" the MiniTiouner-Express that make me smile.
Other thoughts:
The idea to put all components in a compact box is not a good idea( I think), because the whole thing get very hot and it is not a good thing for the components life and more noise can be found on the pcb lines.
there are more noise on I2C ( and perhaps elsewhere) and I2C performance is not so good as MiniTiounerPro where you get very often 100%.
So Minitioune will work more slowly. Look at the timing under the TS leds, with a MiniTiounerPro I get about 110ms with many computers and max of 180ms when I use a little Shuwi tablet or a PIPO (with Atom processor)
What is the value you get?
I cannot say more about the exact performance of this equipment as I don't want to waste more time with it.
Future version of Minitioune I am working"MiniTiounePro"(Minitioune with incorporated Spectrum Analyzer) and/or "DualTioune" (Dual Receiver)) will be no more compatible with the MiniTiouner-Express.

I am sorry to hear this Jean-Pierre, I see the MT sold in EU is a better design, buf or us here is easier and also more economic to get the MT-Express than the one sold in EU, I hope you could keep the suppoer for MT-Express. Thank you.
