Taulimaina o oloa
Tulaga Teuteu
- O oloa ua fa'amaufa'ailogaina i totonu ole Moisture Barrier Bag (MBB) e tatau ona teuina i totonu o se siosiomaga e le fa'afefeteina ole ea ole <40 °C/90%RH.
- O lo'o fa'amauina le module i le maualuga o le maaleale o le susu (MSL) 3.
- A maeʻa ona tatala, e tatau ona faʻapipiʻi le module i totonu ole 168 itula ma tulaga falegaosimea 25±5 °C/60%RH. E tatau ona tao le module pe a le ausia tulaga o loʻo i luga.
ESD
- Fa'ata'ita'iga o le tino o le tagata (HBM): 2000 V
- Fa'ata'ita'iga o masini ua molia (CDM): 500 V
- La'uina o le ea: 6000 V
- Fa'afeso'ota'i fa'ate'a: 4000 V

Manatua
Faʻapipiʻi le module i se tasi toe faʻaleleia. Afai e manaʻomia e le PCBA le tele o toe faʻaleleia, tuʻu le module i luga o le PCB i le taimi o le toe faʻaleleia mulimuli.
tuatusi MAC ma eFuse
Ole eFuse ile ESP32-S2 ua mu ile 48-bit mac_address. O tuatusi moni o loʻo faʻaogaina e le chip i le nofoaga ma AP modes e fetaui ma mac_address i le auala lenei:
- Tulaga tulaga: mac_address
- faiga AP: mac_address + 1
- E fitu poloka i le eFuse mo tagata faʻaoga e faʻaoga. O poloka ta'itasi e 256 bits le lapopo'a ma e tuto'atasi le tusitusi/faitau le fa'atonuina. O le ono o latou e mafai ona faʻaogaina e teu ai faʻailoga faʻailoga poʻo faʻamatalaga tagata faʻaoga, ma o le isi e totoe e faʻaaogaina e teu ai faʻamatalaga faʻaoga.
