Kua huraina e te kaupapa Raspberry Pi te papa Raspberry Pi Pico 2 hou, he whanaketanga anō o ngā papa Pico iti me Pico W, e rua ngā mea e mau ana i tētahi pūmana iti motuhake. Kei te hangaia te papa i tētahi whare Sony, ā, e wātea ana mō te $5. Pērā i ngā papa Pico o mua, ko te tauira hou he mea hanga tuatahi mō te whakamahi me ngā rorohiko Raspberry Pi, te whakawhanake i ngā pūnaha tāmau, me ngā pūnaha whakahaere taputapu. Kei te whakamaheretia kia tukuna he tauira Pico 2 W me te tautoko Nihokikorangi me te Wi-Fi (2.4GHz 802.11n), i runga i te maramara Infineon CYW43439, i muri mai i tēnei tau.
He mea rongonui te papa Pico 2 mō tana whakamahinga o te pūmana iti RP2350 hou. Ki te whakatauritea ki te RP2040 i whakamahia i ngā tauira o mua, he kaha ake te tukatuka ARM Cortex-M33 matua-rua me te DSP me te waeine pūwāhi-maru, e rere ana i te 150 MHz (ki te whakataurite ki te ARM Cortex-M0+ 133 MHz i whakamahia i mua). Hei tāpiri, kei roto ko ngā matua Hazard3 e rua me te hoahoa huinga tohutohu RISC-V, ka taea te whakawhiti i te wā whakaara hei whakakapi i ngā matua ARM Cortex-M33.
Kei roto i te maramara he 520 KB o te RAM o roto (i mua ko te 264 KB), e tautoko ana i ngā waeine mahara QSPI PSRAM o waho, ā, e tuku ana i ngā āhuatanga haumarutanga whakarei ake. Kei te papa Pico 2 te 4 MB o te QSPI Flash, he rua te nui o te mahara o te tauira o mua. Hei tāpiri, he tino hototahi te papa ki ngā tauira o mua e pā ana ki ngā atanga taputapu me ngā pūmanawa e whakamahia ana mō te whakawhanaketanga tono.
Kei roto i te maramara RP2350 ngā taputapu kua hangaia hei tiaki i ngā whakaekenga werohanga hapa, ā, e tautoko ana i te hangarau Arm TrustZone, ka taea te whakamahi hei manatoko i ngā raraunga whakaara mā te whakamahi i tētahi waitohu mamati, ā, e whakarato ana i ngā tohutohu mō te whakateretere i ngā tataunga hash SHA-256 me te whakaputa tau matapōkere pono (TRNG, True Random Number Generator). Hei tāpiri, kei roto ko te 8 KB o te mahara hōtaka kotahi-wā, e āhei ai te tuhi raraunga kāore e taea te whakarerekē, te muku rānei i muri mai.
Ka taea te whakawhanake i ngā tono mā te whakamahi i te C, C++, MicroPython, CircuitPython rānei. Ka taea te whakawhanake i te C/C++ mā te whakamahi i te ētita Visual Studio Code, e wātea ana he tāpiri motuhake mōna. He rawaka ngā āheinga o te maramara hei whakahaere i ngā tono ako mīhini, e wātea ana hoki he tauranga o te anga TensorFlow Lite. Mō te urunga whatunga, e taunakihia ana te puranga whatunga lwIP, kei roto i te Pico SDK mō te whakawhanaketanga tono C, me te pūmanawa MicroPython anō hoki.
I tua atu, i pānuitia ngā hononga mahi tahi me 4D Systems, Adafruit, Bus Pirate, Cytron, Hellbender, Ignys, Invector Labs, Melopero, NewAE, Pimoroni, Seeed, Solder Party, SparkFun, Switch Science, ThisisNotRocketScience, Tiny Circuits, me Wiznet, nāna nei i whakarite ā rātou ake putanga o ngā papa me ngā taputapu e hangai ana ki te pūmana iti RP2350. Ko ngā hua e whakawhanakehia ana ko: ngā parenga gen4-RP2530, te papa Adafruit Feather RP2350 Arduino-hototahi, ngā papa whanaketanga Bus Pirate 5XL me Bus Pirate 6, te pūmana whakahaere Cytron IRIV I/O ahumahi I/O, te pūmana whakahaere karetao MOTION 2350 Pro, ngā papa whanaketanga Hellbender RP2350 me Ignys RP2350, te papa Challenger+ RP2350 BConnect, Melopero Perpetuo LoRa me NewAE RP2350, Pimoroni Tiny 2350, Plasma 2350, PGA2350, Seeed XIAO RP2350, Solder Party RP2350 Stamp, SparkFun Pro Micro me Switch Science Picossci2, ThisIsNotRocketScience Bopp & Steve sound effects synthesizer, te papatohu kēmu Tiny Circuits Thumby Color.
