Arduino UNO R4 coming shortly

Andrew J
Andrew J over 2 years ago

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…

    Yes the board will have two different version with the WiFi version containing ESP32-S3 module which is pretty rich in features. It has upto 16MB of flash memory option(dont know which one Arduino-R4 will have) but surely that will add lots of features in addition to Renesas MCU.

    It will also have CAN bus controller integrated for those who are specifically missing this feature for automation projects.

    Also if you are a library owner or a maintainer than you can apply for free board which you can use to port your library and then submit it. Great chance for open-source contributions.
