Technische Daten
Das Herz des Rasperrry Pi Pico W ist der RP2040, ein von der Raspberry Pi Foundation entwickelter Microcontroller auf Basis eines Dualcore ARM M0+ Kerns.
Die CPU kann mit bis zu 133MHz getaktet werden. Es stehen 264 KByte RAM und 2 MByte Flash zur Verfügung. Für die Wlan- und Bluetoothanbindung sorgt das Infineon IC CYW43439. Eine Messung der CPU-Frequenz ergibt 125MHz:
>>> import machine
machine.freq()
125000000
