- Tom qab unpacking, lub module yuav tsum tau soldered nyob rau hauv 168 teev nrog Hoobkas tej yam kev mob 25 ± 5 ° C / 60% RH. Lub module yuav tsum tau ci yog tias cov xwm txheej saum toj no tsis ua raws.
ESD
- Tib neeg lub cev qauv (HBM): 2000 V
- Charged-device model (CDM): 500 V
- Cua tawm: 6000 V
- Tiv tauj tawm: 4000 V
Reflow Profile
Daim duab 9: Reflow Profile
Nco tseg
Solder lub module nyob rau hauv ib tug reflow. Yog tias PCBA xav tau ntau qhov rov qab, tso lub module rau ntawm PCB thaum lub sij hawm kawg reflow.
MAC Chaw Nyob thiab eFuse
Lub eFuse hauv ESP32-S2 tau hlawv rau hauv 48-ntsis mac_address. Qhov chaw nyob tiag tiag cov nti siv hauv chaw nres tsheb thiab AP hom sib raug rau mac_address raws li hauv qab no:
- Chaw nres tsheb hom: mac_address
- AP hom: mac_address + 1
- Muaj xya qhov thaiv hauv eFuse rau cov neeg siv. Txhua qhov thaiv yog 256 me me thiab muaj kev ywj pheej sau / nyeem lov tes taw tswj. Rau ntawm lawv tuaj yeem siv los khaws tus yuam sij encrypted lossis cov neeg siv cov ntaub ntawv, thiab ib qho ntxiv tsuas yog siv los khaws cov neeg siv cov ntaub ntawv.
