Personally I'm really stoked about the Uno finally getting a 32 bit ARM core. And an M4 at that! I would've thought maybe a M0+ (like the RP Pico) on the Uno and perhaps an M4 on a hypothetical future Mega update.
Good stuff from Arduino. The AVR on the previous Uno revs was getting quite outdated. Simple to use yes, but the Arduino environment mostly abstracts over that and only "power users" ever need to dive into peripheral registers and whatnot (eg to use interrupts).
- polishdude20 3y agoWhat's the difference between an Arduino arm cortex and just getting an adafruit feather board? They have m4's on them and can be programmed with an Arduino IDE and the same tools.
- auxym 3y agoNot much difference, it's just good to see Arduino coming back as decent competition.
- mmoskal 3y agoWell, this M4 is most likely much slower than Rp2040 (2.5x difference in clock speed plus dual core). At the same clock the difference between M0+ and M4 isn't too dramatic (unless you use FPU).
- Dork1234 3y agoI see no reason for them not to go with the RA4M2 version (with 100mhz clock and more memory). The RA4M1 Only has 32KB of memory, and slow clock. Arm M4 is a superset of M0, so clock for clock M4 should be faster. Given the price point for this board compared to the RP2040, I see no reason to give it such a limited processor.
