Izikhonkwane zokubopha
I-ESP32-S2 inezikhonkwane ezintathu zokubopha: GPIO0, GPIO45, GPIO46. I-pin-pin mapping phakathi kwe-ESP32-S2 kunye nemodyuli imi ngolu hlobo lulandelayo, olunokubonwa kwiSahluko sesi-5 seSchematics:
- GPIO0 = IO0
- GPIO45 = IO45
- GPIO46 = IO46
- Isoftware inokufunda amaxabiso eebhithi ezihambelanayo kwirejista "GPIO_STRAPPING".
- Ngexesha lokusetwa kwakhona kwenkqubo yechip (amandla-on-reset, ukusetwa ngokutsha kwe-RTC watchdog, ukusetwa ngokutsha kwe-brownout, ukusetwa ngokutsha kwe-analog super watchdog, kunye nokusetwa kwakhona kwewotshi yekristale yokubona i-glitch), iilatshi zezikhonkwane zokubopha s.ample voltage inqanaba njengamasuntswana okubopha "0" okanye "1", kwaye ubambe la masuntswana de itshiphu inikwe amandla okanye icinywe.
- IO0, IO45 kunye ne-IO46 ziqhagamshelwe kwi-internal pull-up/pull-down. Ukuba azidityaniswanga okanye isekethe yangaphandle eqhagamshelweyo ikwi-impedance ephezulu, ukutsalwa/ukutsalwa kwangaphakathi okubuthathaka kuya kugqiba inqanaba legalelo elingagqibekanga kwezi zikhonkwane zokubopha.
- Ukutshintsha amaxabiso amasuntswana okubopha, abasebenzisi banokufaka ukutsalwa phantsi/ukutsalwa kwangaphandle, okanye basebenzise iGPIOs yeMCU yomkhosi ukulawula ivolthi.tage inqanaba lezi zikhonkwane xa amandla kwi ESP32-S2.
- Emva kokusetha kwakhona, izikhonkwane zokubopha zisebenza njengezikhonkwane eziqhelekileyo zokusebenza.
Jonga kwiTheyibhile yesi-3 yoqwalaselo oluneenkcukacha lwendlela yokuqalisa yezikhonkwane zokubopha.

Phawula
- IFirmware inokuqwalasela iibhithi zokubhalisa ukutshintsha iisetingi ze "VDD_SPI Voltage”.
- I-Internal pull-up resistor (R1) ye-IO45 ayifakwanga kwimodyuli, njengoko i-flash kwimodyuli isebenza kwi-3.3 V ngokungagqibekanga (imveliso nge-VDD_SPI). Nceda uqinisekise ukuba i-IO45 ayiyi kutsalwa phezulu xa imodyuli inikwe amandla yisekethe yangaphandle.
- Ikhowudi ye-ROM ingaprintwa ngaphezulu kwe-TXD0 (ngokungagqibekanga) okanye i-DAC_1 (IO17), ngokuxhomekeke kwi-bit ye-eFuse.
- Xa ixabiso le-eFuse UART_PRINT_CONTROL lithi:
ushicilelo luqhelekile ngexesha lokuqalisa kwaye alulawulwa yi-IO46.- kwaye IO46 ngu-0, ushicilelo luqhelekile ngexesha lokuqalisa; kodwa ukuba i-IO46 ngu-1, ushicilelo luvaliwe.
- IO46 ngu-0, ushicilelo luvaliwe; kodwa ukuba i-IO46 ngu-1, ushicilelo luqhelekile.
- ushicilelo luvaliwe kwaye alulawulwa yi-IO46.

Ukuphathwa kwemveliso
Imeko yoGcino
- Iimveliso ezitywinwe kwi-Moisture Barrier Bag (MBB) kufuneka zigcinwe kwindawo engagungqiyo yomoya we-<40 °C/90%RH.
- Imodyuli ilinganiswe kwinqanaba lobuthathaka bomswakama (MSL) 3.
- Emva kokukhulula, imodyuli kufuneka ithengiswe kwiiyure ze-168 kunye neemeko zefektri 25±5 °C / 60%RH. Imodyuli kufuneka ibhakwe ukuba le miqathango ingasentla ayihlangatyezwanga.
ESD
- Imodeli yomzimba womntu (HBM): 2000 V
- Imodeli yesixhobo esihlawulisiweyo (CDM): 500 V
- Ukukhutshwa komoya: 6000 V
- Ukukhutshwa koqhagamshelwano: 4000 V

Phawula
Solder imodyuli ngokuphinda-phinda okukodwa. Ukuba i-PCBA ifuna ukuhanjiswa kwakhona, beka imodyuli kwi-PCB ngexesha lokuhamba kwakhona kokugqibela.
Iidilesi ze-MAC kunye ne-eFuse
I-eFuse kwi-ESP32-S2 itshiswe yaba yi-48-bit mac_address. Ezona dilesi zisetyenziswa yichip kwisikhululo kunye neendlela ze-AP zihambelana nedilesi ye-mac ngale ndlela ilandelayo:
- Imo yesitishi: mac_dilesi
- Imo ye-AP: mac_idilesi + 1
- Kukho iibhloko ezisixhenxe kwi-eFuse ezinokusetyenziswa ngabasebenzisi. Ibhloko nganye i-256 bits ngobukhulu kwaye inokuzimela ngokubhala / ukufunda ukukhubaza isilawuli. Ezintandathu kuzo zingasetyenziselwa ukugcina isitshixo esifihliweyo okanye idatha yomsebenzisi, kwaye enye eseleyo isetyenziselwa ukugcina idatha yomsebenzisi.
