Nqe lus piav qhia

NodeMCU yog qhov qhib IoT platform. Nws yog programmed los ntawm kev siv Lua scripting language. The platform yog raws eLua qhib qhov haujlwm. Lub platform siv ntau qhov haujlwm qhib, xws li lua-cjson, spiff. Qhov ESP32 NodeMcu no muaj cov firmware uas tuaj yeem ua haujlwm ntawm ESP32 Wi-Fi SoC chips, thiab kho vajtse raws li ESP-32S cov qauv. Nws yog WiFi + Bluetooth kho vajtse uas tuaj yeem nkag tau los ntawm WiFi thiab Bluetooth.

Nta:

Muaj zog ua haujlwm kho vajtse IO raws li arduino

  • micro USB chaw nres nkoj rau lub zog, lub cajmeem thiab debugging
  • Siv Nodejs cov lus zoo sib xws los sau cov ntawv thov network
  • Tus nqi qis tshaj WIFI module

Qhov ntev: 5.5 x 2.8 x 0.1 cm

Hauv qhov kev qhia no, txuas LED's anode rau ESP32's p21 thiab LED's cathode rau ESP32's GND

Kauj Ruam 3: Qauv Qauv Cai

Rub tawm qhov qauv piv txwv no.

Kauj ruam 4: Uploading

Tom qab ua tiav kev kho vajtse sib txuas, koj yuav tsum tso qhov chaws (rub tawm ntawm nplooj ntawv dhau los) rau hauv ESP32 los ntawm kev siv lub micro USB. Ua ntej xa cov cai, koj yuav tsum nruab ESP32 tus tsav tsheb rau hauv koj Arduino IDE, koj tuaj yeem tshawb xyuas ntawm no.
