Umhlaba ubonakala ngathi uhanjiswe kakhulu kumacwecwe anjenge Raspberry Pi o Arduino, kuba ngabo abaphumeleleyo kakhulu. Nangona kunjalo, ayingabo bonke abasebenzisi abonelisekileyo zezi bhodi, kwaye bafuna ezinye iindlela. Kungenxa yokuba bafuna izinto ezithile ezahlukeneyo kunala macwecwe asemthethweni, okanye kuba bafuna ukuzama izinto ezintsha. Kuzo zonke, apha ndiza kubonisa zonke iinkcukacha ze I-Sony Spresense.
Le Sony Spresense yi ibhodi yophuhliso compact kwaye isekwe kumbane ophantsi olawulo lwee-microcontroller zamandla aphantsi. Ngokukodwa kwiichips ze-Sony CXD5602 MCU. Ukongeza, iimpawu zabo zithathela ingqalelo injongo abayiliweyo, kwaye oko kukudala iiprojekthi ze-IoT ngokukhawuleza nangokulula. Konke nge-SDK ephambili esekwe kwiNuttX, okanye ikwasebenzisa iArduino IDE, njengaleyo iyahambelana nayo ...
Iimpawu zobugcisa zakwaSony Spresense
Phina
Ibhodi yeSony Spresense yibhodi elula nexabiso eliphantsi exhaswa yi-Sony CXD5602 chip, i-6-core based microcontroller I-ARM Cortex-M4F ngesantya sewotshi esili-156 Mhz. Inememori ye-8MB flash kunye ne-1.5MB ye-SRAM. Ukongeza, yibhodi yophuhliso olunamandla okusebenza kakuhle, kunye nenkqubo yolawulo lwebhetri ephambili yeeprojekthi ezifuna ukugcina.
Kukwafakwe nenkxaso ye- IGPS, iQZSS kunye neGLONASS eyakhelwe-ngaphakathi kunye ne-eriyali ehlanganisiweyo ebhodini. Kwelinye icala, ikwaquka ii-codec eziphezulu ze-HD 192 Khz / 24-bit codecs, iklasi D yokukhulisa, kunye neziphumo ezininzi ze-MIC (ii-analog ezi-4 kunye namajelo asibhozo edijithali). Kwividiyo, ujongano lwekhamera ye-8-bit kunye ne-Sony 8M CMOS sensors nayo ifakiwe.
Ezinye izinto ezenza ukuba le bhodi yeSony Spresense ilungele iiprojekthi IoT emaphethelweni (emaphethelweni), kokubini kubenzi be-amateur kunye neengcali ezifuna ukwenza into nge-DIY kwezinye iinjongo: ezolimo ezinobuchule, ishishini, isixeko esihlakaniphile, i-automation yasekhaya, imilinganiselo, njl.

Izandiso zeHardware
Ukongeza kwibhodi ephambili yeSony Spresense, ikwenzile inani leefayile ze- ulwandiso lwezixhobo zekhompyutha. Phakathi kwezixhobo onokuthi uzongeze ebhodini zezi:
- Ipleyiti yolwandiso-Ungadibanisa ibhodi ephambili kule bhodi yolwandiso inemilinganiselo ephezulu yokwandisa amandla ebhodi ephambili. Umzekelo, ukongeza amazibuko e-USB, ikhadi le-SD, izikhonkwane ezingaphezulu ze-GPIO, iJack yesandi, njl. Ngale ndlela, uya kuba neplate ethe kratya ngokufanayo kunoko kunokuba kuko, umzekelo, Arduino UNO. Ngendlela, ukunyusa ibhodi ephambili kule bhodi yolwandiso kusetyenziswa isikhombisi-mbini esingu-2 B26B (iBhodi kwiBhodi).
- Ikhamera-Emodyuli inokudityaniswa ngokulula kwi-backplane ukongeza amandla e-imaging kwi-Sony Spresense nayo. Kule meko, sisivamvo se-CMOS esenziwe ngu-Sony kunye ne-5.11MP, ngesisombululo se-2608 × 1960. Zonke zibekwe kwipleyiti encinci ye-24x25mm. Inokudityaniswa ngokuthe ngqo kwibhodi ephambili ngentambo ye-loop kunye ne-Y / C RGB RAW kunye neziphumo zeJPEG, kunye nakwibhodi yolwandiso.
Uqala njani ukusebenzisa ipleyiti
Kwimeko apho uthatha isigqibo sokuba ube nelinye lalamacwecwe, kuyinyani ukuba azikho kangako abaqeqeshiweyo ngokubhekisele kwiArduino okanye kwiRaspberry Pi, kuba ayiyibhodi esasazeke kakhulu. Ngaphandle koko, kukho amanye amaphepha kunye neevidiyo malunga neeprojekthi ezinomdla. Ukongeza, uSony uqobo ubeke kwinkonzo yakho ulwazi oluninzi kunye nezifundo zokuqalisa:
Uyithenga phi iSony Spresense
Ukuba unomdla kule bhodi yophuhliso, ngokuqinisekileyo uyazibuza ukuba ungayithenga phi. Ukuba uhlala eYurophu, uneendlela ezininzi onokukhetha kuzo. Phakathi kwezona zibalaseleyo zezi:
- Ivenkile ye-FRAMOS online: Kuyo uya kufumana zombini ibhodi ephambili kunye nezandiso ezikhoyo.
- Ivenkile ye-RS-kwi-Intanethi kuphela: enye ivenkile eyaziwayo apho uya kufumana khona iSony Spresense Main Board kunye nolunye ulwandiso.
- Ivenkile ekwi-intanethi ye-OKDO: efanayo neyangaphambili, njengenye indlela ukuba ukhetha omnye umthombo wentengo.
- IVIDO.AT Ivenkile ye-Intanethi-Ungayifumana ibhodi ephambili yakwaSony, ibhodi yolwandiso kunye nemodyuli yekhamera.
Kwabo bantu basifundayo Ezinye iindawo zehlabathi, emva koko banokukhetha ezinye iivenkile ezikwi-Intanethi kumazwe abo. Ukuzifumana, ungangena eli elinye ikhonkco.
Ewe amaxabisoNjengoko sele ubonile, ibhodi ephambili ixabisa malunga ne-60 euros, ngelixa ulwandiso lunokuthengwa malunga ne-40 euros, kunye nekhamera kwakhona enye i-40 euros.
