ESP32 Lub Koob Yees Duab Duab Logging Client qhov project tau mob siab rau siv ESP32 micro-maub los rau kev thaij duab thiab xa mus rau lub hauv paus server ntawm Internet siv WiFi muaj peev xwm ntawm ESP32 module.

Lub rooj tsav xwm loj hauv PCB tau tsim los nrog ob lub hom phiaj tseem ceeb hauv siab:

• modularity
• ncaj qha tus qauv lub koob yees duab module txuas

Txhua ntu muaj rau kev xaj ntawm ntau qhov chaw, thiab piv txwv software muaj nyob xws li Git chaw cia khoom.

Kauj ruam 1: Npaj Schematic

ESP32 PROTO WEB CAM board tau tsim los kom haum raws li cov yam ntxwv:

• txuas rau ESP-32S module board (Wroom) sib xws
• txuas rau lub koob yees duab module lossis davhlau ya nyob twg rau 14 IO pins

• ob ESP32 nco FLASH txoj kev

  • USB RS232
  • RS232 nrog phau ntawv txhaj tshuaj
• cim HW ntaus cim
• RTC
• EEPROM nrog RW/R hloov
• ob qhov khoom siv hluav taws xob ntawm 5V
• sab nrauv siv rau ESP-32s pawg thawj coj saib
• microSD daim npav qhov (socket)
• nyuaj-tuav LED
• DC -DC hloov 5V -> 3V3
• txuas ntxiv rau 3 hmuv IO pins, I2C thiab RS232 cuam tshuam

Schematic muaj nyob hauv PDF cov ntaub ntawv, sib koom ob peb qhov kev tshaj tawm pej xeem muaj los ntawm ntau qhov chaw.

Kauj Ruam 2: PCB Ntau Lawm

Siv yav dhau los tam sim no schematic PCB tau tsim los siv tsim software uas tsim cov ntaub ntawv GERBER hauv ob sab SMT/SMD thev naus laus zis nrog cov ntawv me me kom tau txais kev pab ntawm tes txheej txheem txheej txheem thiab siv PCB cov chaw tsim khoom ITD-tim d.o.o. PCB tau ua hauv ROHS.

Ob peb daim duab nthuav tawm cov khoom kawg.

Kauj Ruam 3: Ua tiav ESP32 PROTO WEB CAM Board

Cov ntsiab lus yog cov laug los ntawm txhais tes feem ntau hauv 0805 thiab 1206 thev naus laus zis siv ROHS cov kab laug sab nrog ob peb lub lauj kaub hlau. Thawj yog cov laug ICs, tom qab ntawd cov ntsiab lus passive, tom qab ntawd cov khoom sib txuas. PCB tau ntxuav nrog isopropyl cawv.

Cov txiaj ntsig kawg tau nthuav tawm nrog ob peb daim duab.

Kauj Ruam 4: Ua tiav ESP32 Lub Koob Yees Duab Duab Logging Client

Txhawm rau ua kom tiav ESP32 Lub Koob Yees Duab Duab Logging Client, ntawm ESP32 PROTO WEB CAM PCB tau ntxiv roj teeb CD2032 rau RTC, thiab lub koob yees duab module nrog OV2640 muaj los ntawm TME raws li lub npe lag luam WAVESHARE 8532.

Txhua lub Cheeb Tsam raug sim siv ARDUINO IDE nrog rau ESP32 ntxiv nrog rau pawg xaiv nrog lub npe "ESP32 Dev Module"

Kauj Ruam 5: Xeem Txoj Cai

Txhua qhov chaws xeem muaj nyob ntawm GitLAB:

• LED lub plawv dhia thiab UniqueUnitID (DS18B20) git repo
• I2C (DS3231 RTC, AT24Cxx EEPROM) git repo
• Lub koob yees duab module git repo
