WebThe fastest Arduino suitable for most applications is the Arduino Due, with a clock speed of 84 Mhz and a typical cost of $40. A faster processor can be found on the Portenta H7, which can run up to 480 Mhz. The Portenta however is targeted at real-time image processing and AI applications and is not as suitable as the Due for most projects.
