Hauv no ncej peb yuav ua ib qho kev sib piv: ESP32 vs ESP8266.
Lub ESP32 thiab ESP8266 yog pheej yig Wi-nkaus modules txig haum rau DIY tej yaam num hauv Internet ntawm Yam (IoT) teb. Cov modules tuaj nrog GPIOs, kev txhawb rau ntau hom kev cai xws li SPI, I2C, UART, thiab ntau dua. Qhov zoo tshaj plaws, lawv tuaj nrog wireless tes hauj lwm, uas teev lawv sib nrug ntawm lwm cov microcontrollers xws li Arduino.That txhais tau tias koj tuaj yeem yooj yim remotely tswj thiab soj qab li wi-nkaus, thiab tus nqi tsawg.
Specifications: ESP32 vs ESP8266
Lub ESP32 yog lub ESP8266 successor. Nws ntxiv ib qho CPU tub ntxhais, Wi-nkaus ceev, ntau dua GPIOs, thiab txhawb Bluetooth 4.2 thiab Bluetooth tsawg zog. Ntxiv mus, ESP32 los nrog kov sensors, built-in nrog cov nyhuv sensors thiab qhov kub thiab txias sensors.Lub laug cam yog pheej yig, ESP32 yog me ntsis kim kim.
Cov nram qab no qhia tau hais tias lub ntsiab sib txawv ntawm ESP8266 thiab ESP32 processors.
Ntau GPI nyob rau hauv ESP32
Lub ESP32 muaj ntau lub koob ntxiv ntawm ESP8266, thiab koj tuaj yeem txiav txim siab xaiv cov koob twg hauv UART, I2C, los yog SPI - koj cia li teem caij rau ntawm txoj cai. Qhov no yog ua tau vim yog lub ESP32 nti siv cov kev siv ntau yam uas tso cai rau muab ntau lub zog rau tib tus pin.
Wrapping Up
Yog li, txij ntawm no koj yuav tsum tau nug: Kuv puas tsim nyog tau txais ESP8266 los sis ESP32?
Nws yeej nyob ntawm seb koj xav ua dab tsi. Muaj chaw seem rau ob qho tib si pab pawg, thiab ob leeg muaj kev ncaj ncees thiab kev tsim.
Cov ESP8266 yog pheej yig tshaj li ESP32. Txawm hais tias nws tsis muaj ntau npaum li cov functionalities, nws ua haujlwm zoo xwb rau feem coob ntawm cov yooj yim DIY IoT tej yaam num. Tsis tas li ntawd xwb, vim nws yog "laus dua" nws yog ntau ntau qhov kev txhawb nqa ntawm software, thiab koj yuav nrhiav kev pab yooj yim dua. Txawm li cas los xij, nws muaj qee cov kev txwv thaum nws los txog rau ntawm daim duab khawm GPIO, thiab nws yuav tsis muaj lub koob txaus rau qhov koj npaj siab ua. Yog tias qhov no, koj yuav tsum tau txais ib qho ESP32.
Lub ESP32 muaj hwj chim ntau dua li lub ESP8266, muaj ntau dua GPIO nrog ntau lub zog, Wi-nkaus ceev, thiab txhawb Bluetooth. Ntau tus neeg xav hais tias lub ESP32 nyuaj dua rau kev tshaj li ESP8266 vim nws muaj ntau dua. Nyob rau hauv peb lub tswv yim, nws yog ib qho yooj yim rau kev kawm ESP32 ua lub ESP8266, tshwj xeeb yog tias koj npaj siab mus rau qhov kev kawm nws siv hom Arduino.
Txawm li cas los xij, lub ESP32 muaj qee yam qia ib yam thiab. Ua ntej, nws tseem kim tshaj ESP8266. Yog li, yog tias koj tab tom ua qhov project IoT yooj yooj yim, tus ESP8266 yuav ua tus ua kom yuam kev rau tus nqi qis dua. Ntxiv thiab, vim tias nws tsis ntev los no tshaj li ESP8266, tsis yog tag nrho software tau tsim los ua tus tshaj tawm ntawm ESP32 functionalities, muaj kev pab tsawg, thiab ntau tshaj yoov. Tab sis nyob ntev ces cov teeb meem no yuav raug kho, thiab yuav muaj chaw rau ob qho tib si.
