Raspberry Pi Project tau nthuav tawm Raspberry Pi Pico W lub rooj tsavxwm tshiab, txuas ntxiv kev txhim kho ntawm lub rooj tsav xwm me me Pico, nruab nrog tus tswv RP2040 microcontroller. Cov ntawv tshiab yog qhov txawv los ntawm kev sib koom ua ke ntawm kev txhawb nqa Wi-Fi (2.4GHz 802.11n), ua raws li lub hauv paus ntawm Infineon CYW43439 nti. CYW43439 nti kuj txhawb Bluetooth Classic thiab Bluetooth Low-Energy, tab sis lawv tseem tsis tau suav nrog hauv pawg thawj coj. Tus nqi ntawm lub rooj tsavxwm tshiab yog $ 6, uas yog ob duas las ntau dua qhov kev xaiv thawj zaug. Ntawm thaj chaw ntawm daim ntawv thov, ntxiv rau kev sib koom nrog Raspberry Pi khoos phis tawj, txhim kho cov kab ke thiab kev tswj hwm rau ntau yam khoom siv, qhov kev xaiv Wi-Fi tau muab tso rau hauv lub platform rau kev tsim Internet ntawm Yam (Internet of Things) cov khoom siv sib cuam tshuam ntawm ib qho. network.
RP2040 nti suav nrog dual-core ARM Cortex-M0 + (133MHz) processor nrog 264 KB ntawm on-board RAM (SRAM), DMA maub los, ntsuas kub, lub sijhawm, thiab USB 1.1 maub los. Lub rooj tsavxwm muaj 2 MB ntawm Flash nco, tab sis lub nti txhawb kev nthuav dav txog 16 MB. Rau I / O, GPIO cov chaw nres nkoj tau muab (30 tus pins, ntawm 4 yog muab faib rau cov tswv yim analog), UART, I2C, SPI, USB (tus neeg siv khoom thiab tus tswv tsev nrog kev txhawb nqa rau booting ntawm drives hauv UF2 hom) thiab tshwj xeeb 8 pins PIO ( Programmable I / O lub xeev cov cav tov) los txuas koj tus kheej peripherals. Lub hwj chim tuaj yeem muab tau nyob rau hauv thaj tsam ntawm 1.8 txog 5.5 volts, uas tso cai rau koj siv ntau yam khoom siv hluav taws xob, suav nrog ob lossis peb lub roj teeb AA roj teeb lossis cov roj teeb lithium-ion.
Cov ntawv thov tuaj yeem tsim siv C, C ++, lossis MicroPython. MicroPython chaw nres nkoj rau Raspberry Pi Pico tau npaj ua ke nrog tus sau ntawm qhov project thiab txhawb nqa tag nrho cov yam ntxwv ntawm lub nti, suav nrog nws tus kheej interface rau txuas PIO txuas ntxiv. Rau kev txhim kho rau RP2040 nti siv MicroPython, Thonny kev koom ua ke programming ib puag ncig tau hloov kho. Lub peev xwm ntawm cov nti yog txaus los khiav cov ntawv thov kev daws teeb meem kev kawm tshuab, rau kev txhim kho qhov chaw nres nkoj ntawm TensorFlow Lite lub moj khaum tau npaj. Rau kev nkag mus rau hauv lub network, nws tau thov kom siv lwIP network pawg, uas yog suav nrog hauv cov ntawv tshiab ntawm Pico SDK rau kev tsim cov ntawv thov hauv C lus, nrog rau hauv cov firmware tshiab nrog MicroPython.
