Good idea Matteo :-) I bought rPI-Pico(-W) and rpi-Pico-2(-W) 4 boards just for testing but I am not familiar with the hw :-) Would it be good to allow users to select clock frequency? If 125MHz -> 200MHz that would imply increased power consumption too? Can it be easily changed at runtime? -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
