Nā Paʻi Kāʻei
ESP32-S2 'ekolu mau pine strapping: GPIO0, GPIO45, GPIO46. ʻO ka palapala ʻāina pin-pin ma waena o ESP32-S2 a me ka module penei, hiki ke ʻike ʻia ma ka Mokuna 5 Schematics:
- GPIO0 = IO0
- GPIO45 = IO45
- GPIO46 = IO46
- Hiki i nā polokalamu ke heluhelu i nā waiwai o nā bits like mai ka hoʻopaʻa inoa "GPIO_STRAPPING".
- I ka wā o ka hoʻonohonoho hou ʻana o ka ʻōnaehana o ka chip (power-on-reset, RTC watchdog reset, brownout reset, analog super watchdog reset, and crystal clock glitch detection reset), nā kī o nā pine s.ample ka voltage like me ke kāʻei ʻana i nā ʻāpana o "0" a i ʻole "1", a paʻa i kēia mau ʻāpana a pau ka mana a pani ʻia paha.
- Hoʻopili ʻia ʻo IO0, IO45 a me IO46 i ka huki huki / huki i lalo. Inā ʻaʻole i hoʻopili ʻia lākou a i ʻole he kiʻekiʻe ka impedance o ke kaapuni waho i hoʻopili ʻia, ʻo ka huki huki / huki ʻana i lalo e hoʻoholo i ka pae hoʻokomo paʻamau o kēia mau pine strapping.
- No ka hoʻololi ʻana i nā waiwai strapping bit, hiki i nā mea hoʻohana ke hoʻohana i nā mea huki huki i lalo/pull-up i waho, a i ʻole e hoʻohana i nā GPIO o ka MCU e hoʻokele i ka vol.tagʻO ka pae o kēia mau pine i ka wā e mana ana ma ESP32-S2.
- Ma hope o ka hoʻoponopono hou ʻana, hana nā pine strapping e like me nā pine hana maʻamau.

- Pono e mālama ʻia nā huahana i hoʻopaʻa ʻia i loko o ka Moisture Barrier Bag (MBB) i loko o kahi kaiapuni noncondensing o <40 °C/90%RH.
- Ua helu ʻia ka module ma ke kiʻekiʻe o ka moisture sensitivity level (MSL) 3.
- Ma hope o ka wehe ʻana, pono e kūʻai ʻia ka module i loko o 168 mau hola me nā kūlana hale hana 25±5 °C/60%RH. Pono e kālua ʻia ka module inā ʻaʻole i hoʻokō ʻia nā kūlana i luna.

Hoʻopili i ka module i hoʻokahi reflow. Inā makemake ka PCBA i nā reflows he nui, e kau i ka module ma ka PCB i ka wā o ka reflow hope loa.
Nā helu MAC a me ka eFuse
Ua puhi ʻia ka eFuse ma ESP32-S2 i 48-bit mac_address. ʻO nā ʻōlelo maoli i hoʻohana ʻia e ka chip ma ke kikowaena a me nā mode AP e pili ana i ka mac_address ma ke ʻano penei:
- Ke ano o ke kahua: mac_address
- ʻano AP: mac_address + 1
- ʻEhiku mau poloka ma eFuse no nā mea hoʻohana e hoʻohana. He 256 mau ʻāpana ka nui o kēlā me kēia poloka a loaʻa iā ia ka mea hoʻoponopono hoʻopau i ke kākau/heluhelu. Hiki ke hoʻohana ʻia ʻeono o lākou no ka mālama ʻana i ke kī i hoʻopili ʻia a i ʻole ka ʻikepili mea hoʻohana, a ʻo ke koena e hoʻohana wale ʻia e mālama i ka ʻikepili mea hoʻohana.

Pono-Heluhelu Palapala
Hāʻawi ka loulou ma lalo i nā palapala e pili ana iā ESP32-S2.
- ESP32-S2 Palapala Hoʻohana
Hāʻawi kēia palapala i kahi hoʻolauna i nā kikoʻī o ka hāmeʻa ESP32-S2, me ka ʻoi akuview, wehewehe pine, wehewehe hana, pili pili, ʻano uila, etc. - Alakaʻi Papahana ESP-IDF
Hāʻawi ia i nā palapala nui no ESP-IDF mai nā alakaʻi ʻenehana a hiki i ka ʻōlelo API. - ESP32-S2 Palapala Kiʻi
Hāʻawi ka manual i ka ʻike kikoʻī e pili ana i ka hoʻohana ʻana i ka hoʻomanaʻo ESP32-S2 a me nā peripheral. - Espressif Products Order Information

Eia nā kumuwaiwai e pili ana iā ESP32-S2.
ESP32-S2 BBS
- He Community Engineer-to-Engineer (E2E) kēia no ESP32-S2 kahi e hiki ai iā ʻoe ke kau i nā nīnau, kaʻana like i ka ʻike, ʻimi i nā manaʻo, a kōkua i ka hoʻoponopono ʻana i nā pilikia me nā hoa loea.
