Raspberry Pi projekts ir izstr\u0101d\u0101jis jauno Raspberry Pi Pico 2 plati, kas turpina mini pl\u0101t\u0146u Pico un Pico W att\u012bst\u012bbu, kas ir apr\u012bkotas ar pa\u0161izstr\u0101d\u0101tu mikrocontrolieri. Plati ra\u017eo Sony r\u016bpn\u012bca un t\u0101 ir pieejama par 5 dol\u0101riem. T\u0101pat k\u0101 iepriek\u0161\u0113j\u0101s Pico pl\u0101tes, jaunais modelis galvenok\u0101rt ir paredz\u0113ts kop\u012bgai izmanto\u0161anai ar Raspberry Pi datoriem, k\u0101 ar\u012b ieb\u016bv\u0113to sist\u0113mu un da\u017e\u0101du ier\u012b\u010du vad\u012bbas sist\u0113mu izstr\u0101dei.

Pico 2 plate ir iev\u0113rojama ar jauno mikrocontrolieri RP2350, kas, sal\u012bdzinot ar iepriek\u0161\u0113jo mode\u013cu mikrocontrolieri RP2040, ietver jaud\u012bg\u0101ku divkodolu ARM Cortex-M33 procesoru ar DSP un peldo\u0161\u0101s komata apr\u0113\u0137inu bloku, kas darbojas ar 150MHz frekvenci (iev\u0113roti iepriek\u0161 bija ARM Cortex-M0+ 133 MHz). Turkl\u0101t ir iek\u013cauti divi izv\u0113les Hazard3 kodoli ar RISC-V komandu kopas arhitekt\u016bru, kurus var p\u0101rsl\u0113gties iel\u0101d\u0113jot, lai izmantotu viet\u0101 ARM Cortex-M33 kodolu. <\/p>\n
