Seems like a cool project, but with such weak specs what can one actually do with this?
This thing is like 5x more MHz with 8x more RAM than an Arduino. 18MHz and 128kB is plenty.
Remember: the Apollo flight computer (Moon landing) was accomplished with 2MHz and 4096 bytes of RAM. Even the Arduino is more computationally powerful than the Moon Lander.
arduinos run at 16 MHz
I stand corrected.
they actually could be made to run at 20 MHz with some software tweaks. But sram is still much less
That's what confused me.
Modern versions of ATMega (ex: the AVR DD) run at 4MHz by default, even if they can go up to 24MHz. Looking back at ATMega328p (which powered the Arduino Uno, aka the one that got popular), the ATMega328p defaults to 1MHz. (IE: 8MHz internal oscillator with 1/8 clock division == 1MHz overall)
