I like people that try to get the most out of the integrated peripherals in creative ways. It's a dying craft in a world where a 300 MHz "micro" is just a dollar away.
What kind of 300MHz MCU can you find for a dollar?
Welll.... the RP2040 is a dollar and can be overclocked to 300MHz (peripheral clocks get a little weird around that point, but they can be clocked down).
The name polpo sounds familiar - are you creator of PicoGus?
