I have the same question

here:

Uno R4 minima quartz or not

Hello all. When I look at the r4 minimim schematics, I see a 16Mhz quartz on it, but this board presentation says it works at 48 Mhz. So what's true ? Is it really a 16 Mhz quartz on the board ? If yes, does the board really running at 48 Mhz ? Thanks [image]
