Arduino UNO R4 coming shortly

Andrew J

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.

  • Yes this is a curious addition to the Arduino family. The spec isn't ground breaking but it is very sturdy for Arduino-type applications. I see clock speed is set at 48MHz, with 32kB of SRAM and 256kB of flash. There are two interesting offerings. First, is that the board has a power regulator that can handle with 24V, which they say has an improved thermal design. Cool. And the second is that it provides a CAN bus. Also cool. I suspect this product will suit industrial applications quite well.
