Mashruuca Raspberry Pi waxa uu soo bandhigay guddi cusub oo Raspberry Pi Pico W ah, kaas oo sii wada horumarinta guddida yar ee Pico, oo ku qalabaysan kontorool RP2040 ah oo iska leh. Daabacaad cusub waxaa lagu kala saaray is dhexgalka taageerada Wi-Fi (2.4GHz 802.11n), oo lagu hirgeliyay gundhigga Infineon CYW43439. Chip-ka CYW43439 wuxuu kaloo taageeraa Bluetooth Classic iyo Bluetooth Low-Tamarta, laakiin weli kuma jiraan guddiga. Guddiga cusub ayaa ku kacaya $6, taas oo laba doollar ka qaalisan dooqa koowaad. Waxaa ka mid ah meelaha codsiga, marka lagu daro la wadaagista kombiyuutarada Raspberry Pi, horumarinta nidaamyada ku-xidhan iyo nidaamyada xakamaynta aaladaha kala duwan, ikhtiyaarka Wi-Fi wuxuu u taagan yahay madal lagu abuurayo aaladaha Internetka ee waxyaabaha dhexmara shabakada.
Chip-ka RP2040 waxa ku jira laba-core ARM Cortex-M0+ (133MHz) processor oo leh 264 KB ee xusuusta gudaha gelitaanka random (SRAM), kontaroolaha DMA, dareeme heerkulka, saacad iyo USB 1.1 kantaroole. Looxa wuxuu ka kooban yahay 2 MB ee xusuusta Flash, laakiin chip-ku wuxuu taageeraa ballaarinta ilaa 16 MB. I/O waxaa jira dekedo GPIO ah (30 biin, 4 ka mid ah waxay u heellan yihiin gelinta analogga), UART, I2C, SPI, USB (macmiilka iyo martigeliyaha oo taageero ka helaya darawallada qaabka UF2) iyo 8 biin oo khaas ah PIO ( Mashiinnada gobolka I/O ee la baran karo) si loogu xidho meelaha kuu dhow. Awoodda waxaa laga heli karaa 1.8 ilaa 5.5 volts, taas oo u oggolaanaysa ilo koronto oo kala duwan, oo ay ku jiraan laba ama saddex baytariyada AA caadiga ah ama baytariyada lithium-ion caadiga ah.
Si loo abuuro codsiyada, C, C++ ama MicroPython waa la isticmaali karaa. Dekadda MicroPython ee Raspberry Pi Pico waxaa si wadajir ah loo diyaariyey qoraaga mashruuca waxayna taageertaa dhammaan awoodaha chip-ka, oo ay ku jirto is-dhexgal u gaar ah oo loogu talagalay isku xirka kordhinta PIO. Deegaanka barnaamijka isku dhafan ee Thonny ayaa loo habeeyey horumarinta RP2040 chip iyadoo la isticmaalayo MicroPython. Awoodaha chip-ku waa ku filan yahay in lagu socodsiiyo codsiyada xallinta mashaakilaadka barashada mashiinka, horumarinta taas oo deked ka mid ah qaab dhismeedka TensorFlow Lite la diyaariyey. Helitaanka shabakada, waxaa la soo jeediyay in la isticmaalo xirmooyinka shabakada lwIP, kaas oo lagu daray nooca cusub ee Pico SDK ee horumarinta codsiyada luqadda C, iyo sidoo kale firmware-ka cusub ee MicroPython.
