Izikhonkwane zokubopha
I-ESP32-S2 inezikhonkwane ezintathu zokubopha: GPIO0, GPIO45, GPIO46. Imephu yephinikhodi phakathi kwe-ESP32-S2 nemojula imi kanje, engabonwa kuSahluko 5 Schematics:
- GPIO0 = IO0
- GPIO45 = IO45
- GPIO46 = IO46
- Isofthiwe ingafunda amanani amabhithi ahambisanayo kurejista ”GPIO_STRAPPING”.
- Ngesikhathi sokusetha kabusha isistimu ye-chip (ukusetha kabusha amandla, ukusethwa kabusha kwe-watchdog ye-RTC, ukusetha kabusha i-brownout, ukusetha kabusha i-analog super watchdog, nokusetha kabusha ukutholwa kwe-crystal clock clock), amalashi wezikhonkwane zokubophaample voltage ileveli njengamabhithi okubopha okuthi "0" noma "1", bese ubamba lezi zingcezu kuze kube yilapho i-chip yehliswa amandla noma ivaleka.
- I-IO0, IO45 ne-IO46 zixhunywe ekudonseleni phezulu/ukudonsa phansi kwangaphakathi. Uma zingaxhunyiwe noma isekethe yangaphandle exhunyiwe inamandla amakhulu, ukudonsela phezulu/ukudonsela phansi okubuthakathaka okungaphakathi kuzonquma ileveli yokufaka ezenzakalelayo yalezi zikhonkwane zokubopha.
- Ukushintsha amanani ebhithi yokubopha, abasebenzisi bangasebenzisa ukumelana kwangaphandle kokudonsela phansi/ukudonsa, noma basebenzise ama-GPIO osokhaya we-MCU ukuze balawule ivolumu.tage ileveli yalawa maphini uma inikwa amandla ku-ESP32-S2.
- Ngemva kokusetha kabusha, izikhonkwane zokubopha zisebenza njengezikhonkwane ezivamile.

Ukuphathwa Komkhiqizo
Isimo Sesitoreji
- Imikhiqizo evalwe Ku-Moisture Barrier Bag (MBB) kufanele igcinwe endaweni yomoya engancibiliki engu-<40 °C/90%RH.
- Imojula ikalwe ezingeni lokuzwela umswakama (MSL) 3.
- Ngemva kokuqaqa, imojuli kufanele ithengiswe phakathi kwamahora angu-168 ngezimo zasembonini ezingu-25±5 °C/60%RH. Imojuli idinga ukubhakwa uma izimo ezingenhla zingahlangatshezwana nazo.
ESD
- Imodeli yomzimba womuntu (HBM): 2000 V
- Imodeli yedivayisi eshajiwe (CDM): 500 V
- Ukukhishwa komoya: 6000 V
- Ukukhishwa kothintana naye: 4000 V

Qaphela
Solder imojuli ngokugeleza kabusha okukodwa. Uma i-PCBA idinga ukugeleza kabusha okuningi, beka imojuli ku-PCB ngesikhathi sokugeleza kabusha kokugcina.
Amakheli e-MAC kanye ne-eFuse
I-eFuse ku-ESP32-S2 ishiswe yaba yi-48-bit mac_address. Amakheli angempela i-chip ewasebenzisayo esiteshini kanye nezindlela ze-AP ahambisana ne-mac_address ngale ndlela elandelayo:
- Imodi yesiteshi: mac_address
- Imodi ye-AP: mac_address + 1
- Kunamabhulokhi ayisikhombisa ku-eFuse abasebenzisi abangawasebenzisa. Ibhulokhi ngayinye inosayizi wamabhithi angu-256 futhi inesilawuli esizimele sokubhala/sokufunda. Eziyisithupha zazo zingasetshenziswa ukugcina ukhiye obethelwe noma idatha yomsebenzisi, futhi eyodwa esele isetshenziswa kuphela ukugcina idatha yomsebenzisi.

Amadokhumenti Okufanele Uwafunde
Isixhumanisi esilandelayo sihlinzeka ngamadokhumenti ahlobene ne-ESP32-S2.
- Incwadi Yomsebenzisi ye-ESP32-S2
Lo mbhalo unikeza isingeniso ezincazelweni zezingxenyekazi zekhompuyutha ze-ESP32-S2, okuhlanganisa nokungaphezuluview, izincazelo zamaphini, incazelo yokusebenza, isixhumi esibonakalayo se-peripheral, izici zikagesi, njll. - I-ESP-IDF Programming Guide
Ibamba imibhalo ebanzi ye-ESP-IDF kusukela kumhlahlandlela wezingxenyekazi zekhompuyutha kuya kunkomba ye-API. - I-ESP32-S2 I-Technical Reference Manual
Imanuwali inikeza imininingwane enemininingwane yokuthi isetshenziswa kanjani inkumbulo ye-ESP32-S2 kanye nama-peripherals. - Ulwazi olu-oda lwemikhiqizo ye-Espressif
Okufanele Ube Nezinsiza
Nazi izinsiza okufanele ube nazo ezihlobene ne-ESP32-S2.
I-ESP32-S2 BBS
- Lona Umphakathi Wonjiniyela ukuya kuNjiniyela (E2E) we-ESP32-S2 lapho ungathumela khona imibuzo, wabelane ngolwazi, uhlole imibono, futhi usize ukuxazulula izinkinga nabanye onjiniyela.
