De Raspberry Pi Pico W is een ontwikkelboard, gebouwd rond de krachtige RP2040 microcontroller.
Aan beide zijden van de Pico W zitten 40 GPIO (general-purpose input/output)-pinnen. Deze pinnen worden gebruikt om elektronische componenten aan te sluiten, de Pico W aan computerapparatuur te koppelen en persoonlijke projecten te bouwen. Deze pinnen vormen de verbinding tussen je code en de echte wereld. Je kunt de Pico W gebruiken om je huis te automatiseren, robots te besturen of huishoudelijke apparaten te beheren. Of je kunt gewoon spelen met knoppen, zoemers, sensoren, en leuke widgets en gadgets bouwen.
Dankzij de draadloze mogelijkheden van de Pico W kun je nu ook communiceren met online diensten, gegevens van het internet halen via API’s (application programming interfaces) en informatie draadloos opslaan.
Raspberry Pi Pico RP2040 W
Raspberry Pi Pico W is a microcontroller board based on the Raspberry Pi RP2040 microcontroller chip.
Raspberry Pi Pico W has been designed to be a low cost yet flexible development platform for RP2040 with a 2.4 GHz wireless interface using an Infineon CYW43439. The wireless interface is connected via SPI to the RP2040.
The RP2040 microcontroller chip (“Raspberry Silicon”) offers a dual-core ARM Cortex-M0+ processor (133 MHz), 256 KB RAM, 30 GPIO pins, and many other interface options. In addition, there is 2 MB of on-board QSPI flash memory for code and data storage.
