Arduino UNO R4 coming shortly

Saw this today: Arduino UNO r4 on the official site.

Renesas processor, 32-bit, 256MB ram CAN bus and more. Should really open up new projects and give the Mega a run for its money. Actually makes you wonder what they might do with that one now.

Neat. What's also great to see is they are continuing to invest in the arduino library catalog

Hmm. An interesting development indeed. Still 5V, but the loss of AVR doesn't feel like Uno to me ... But perhaps a good move overall ... I wonder how it stacks up to the SAMD-family that has been running…

Looks good! I might actually want to finally use an Uno! However this could be a bit of a pain, unless VCC can be changed to 3.3V, otherwise level shifters will be needed with 3.3V logic. Granted lots…

Now this is going to be interesting.

What is hidden behind the yellow box and what will be the price?

Fun fact: there is already a UNO R4 plus on the market, but it is just a knock-off 8 bit micro with clever marketing.

I am not certain it is hiding anything. The colored rectangles could be decoration.

I did find it interesting that Massimo and Fabio (CEO) were at the Arduino Day event in Chicago, where they announced it via live stream. Yet, they did not have one with them.

The answer is chip shortage as always. They don't know yet, if they can buy the processor in BGA-400 or SOIC-8.

Pin variation is because they can extend product's life based on "number of remaining pins/number of socket insertions" graph as in famous Signetics Write-only-memory datasheet?
