Chikwata cheRaspberry Pi chakaburitsa iyo RP2040 board-on-chip ine 40nm architecture: Raspberry Pi Pico.
RP2040 Tsanangudzo:
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264Kb RAM
- Inotsigira kusvika ku16MB Flash memory kuburikidza nebhazi rakatsaurirwa reQSPI
- DMA controller
- 30 GPIO mapini, 4 ayo anogona kushandiswa seanalog yekupinda
- 2 UART, 2 SPI uye 2 I2C controllers
- 16 PWM chiteshi
- USB 1.1 controller ine host mode rutsigiro
- 8 Raspberry Pi I/O (PIO) inorongwa mamiriro emuchina
- USB misa-yekuchengetedza bhutsu modhi ine firmware rutsigiro kuburikidza neUF2
Raspberry Pi Pico yakagadzirwa seyekutanga, isingadhure (chete $4) bhodhi yeRP2040. Iine RP2040 ine 2 MB ye flash memory uye simba rekupa chip rinotsigira kupinza voltages kubva 1,8 kusvika 5,5 V. Izvi zvinobvumira Pico kuti ishandiswe kubva kwakasiyana-siyana, kusanganisira maviri kana matatu AA mabhatiri akatevedzana kana kubva kune imwe chete. lithium-ion bhatiri.
Mabhodhi akavakirwa paRP2040 chip achakurumidza kuwanikwa kubva kune vechitatu-bato vagadziri:
