Getting quite an upgrade!
Arduino evolves with Renesas-based 32-bit Uno R4 versions (electronicsweekly.com)

 

Looks potentially interesting but no mention of price which is pretty important. We‘ll have to wait and see…

 

From good ole AliX. Heck they might even be the real thing, maybe... Kinda intriguing as to what the LED matrix might do.

 

I may buy one... Only £15.48 here.. Worth it just for the 12 bit DAC on pin A0.. I want to see how fast I can cram out a decent sine wave..

It looks like nice bare-metal motor-control hardware I'd use without the Arduino framework. It seems to be missing a general single/double precision FPU but does have a Trigonometric Function Unit (TFU)

They have CANFD (CAN with Flexible Data-rate) so it's compatible with the home embedded network I'm building out for projects.

Edit: This is not the processor they used on the R4, see my updated comments below. This model has a huge number of variations.

Hello,

There also seems to be a wifi version announced:

I screwed up. The 48MHz version they used on the R4 does have a FPU but critically doesn't have CAN FD. Bummer.

At the risk of starting an argument my view is that this is a sad attempt to play catch-up

Sad, because the Arduino UNO was such an amazing pioneer of easy to use processor boards, probably used worldwide by most students and hobbyists which has influenced a generation of young engineers. The ESP32 and others have leaped ahead with on board WiFi, bluetooth etc. 48MHz is four times as fast but the basic Seeduino XIAO has had 48MHz for ages and faster clock speeds are commonplace. The UNO R3 at 16MHz struggled to analogRead() at 9kHz - the XIAO can do 70kHz.

And they've kept the exact same footprint with the annoying pin offset. Okay for backward compatability with all the shields out there but difficult for anyone using strip board to build their own circuits around the UNO. Whilst this was a good ploy to encourage manufacturers of various shields it's contributed to a reluctance of users to design and build their own shields. I actually had some special strip board made.

CAN bus is a nice addition. The LED matrix is bordering on pointless if you plan to add a shield on top to actually do something in the real world. Better to have included an area where users could mount some additional components, or maybe an H Bridge for driving a motor.

I hope it works for them - but I personally doubt it.

 

They say R4 is backward compatible to R3, but they changed the I/O current spec. It wasn't "correct" for R3 anyway.

They also don't mention how much EEPROM R4 has.
