Aikin Raspberry Pi ya ƙaddamar da sabon allo, Rasberi Pi Pico 2, wanda ke ci gaba da haɓaka ƙananan allunan Pico da Pico W, sanye take da microcontroller na ƙirarsa. An kera allon a masana'antar Sony kuma ana samunsa akan $5. Kamar allunan Pico da suka gabata, sabon samfurin yana da niyya da farko don rabawa tare da kwamfutocin Raspberry Pi, haɓaka tsarin da aka haɗa da tsarin sarrafawa na na'urori daban-daban.
