Gulu la Raspberry Pi latulutsa RP2040 board-on-chip yokhala ndi 40nm zomangamanga: Raspberry Pi Pico.
Mbiri ya RP2040
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264Kb RAM
- Imathandizira mpaka 16MB Flash memory kudzera pa basi yodzipereka ya QSPI
- Woyang'anira DMA
- 30 GPIO zikhomo, 4 zomwe zingagwiritsidwe ntchito ngati zolowetsa zaanalogi
- 2 UART, 2 SPI ndi 2 I2C olamulira
- 16 PWM njira
- USB 1.1 chowongolera chokhala ndi chithandizo chamtundu wa host
- 8 Raspberry Pi I/O (PIO) makina osinthika a boma
- USB mass-storage boot mode ndi chithandizo cha firmware kudzera UF2
Raspberry Pi Pico idapangidwa ngati bolodi yoyambirira, yotsika mtengo (yokha $4) ya RP2040. Lili ndi RP2040 yokhala ndi 2 MB ya kukumbukira kung'anima ndi chipangizo chamagetsi chomwe chimathandizira magetsi olowera kuchokera ku 1,8 mpaka 5,5 V. Izi zimathandiza kuti Pico ikhale yoyendetsedwa kuchokera kuzinthu zosiyanasiyana, kuphatikizapo mabatire awiri kapena atatu AA mndandanda kapena kuchokera kumodzi. batri ya lithiamu-ion.
Ma board otengera RP2040 chip nawonso apezekanso posachedwa kuchokera kwa opanga gulu lachitatu:
