Ithimba le-Raspberry Pi likhiphe i-RP2040 board-on-chip ene-40nm yezakhiwo: I-Raspberry Pi Pico.
Imifanekiso ye-RP2040
- I-Dual-core Arm Cortex-M0+ @ 133MHz
- 264Kb RAM
- Isekela inkumbulo ye-Flash efika ku-16MB ngebhasi elizinikele le-QSPI
- Isilawuli se-DMA
- 30 izikhonkwane ze-GPIO, ezi-4 zazo zingasetshenziswa njengokufakwa kwe-analog
- 2 UART, 2 SPI kanye nezilawuli ezingu-2 I2C
- 16 amashaneli e-PWM
- Isilawuli se-USB 1.1 esinosekelo lwemodi yokusingatha
- 8 Imishini yezwe ehlelekayo ye-Raspberry Pi I/O (PIO).
- Imodi yokuqalisa yesitoreji esikhulu se-USB enokusekelwa kwe-firmware nge-UF2
I-Raspberry Pi Pico yakhelwe njengebhodi yoqobo, engabizi (kuphela $4) ye-RP2040. Iqukethe i-RP2040 eno-2 MB wememori ye-flash kanye ne-chip yamandla esekela ama-voltage okokufaka ukusuka ku-1,8 ukuya ku-5,5 V. Lokhu kuvumela i-Pico ukuthi inikwe amandla ngemithombo ehlukahlukene, okuhlanganisa amabhethri amabili noma amathathu AA ochungechungeni noma asuka kweyodwa. ibhethri ye-lithium-ion.
Amabhodi asuselwe ku-chip ye-RP2040 nawo azotholakala maduze kubakhiqizi bezinkampani zangaphandle:
