Potoloho
3.1. Tsamaiso
WizFi360 e na le potoloho e bonolo haholo. O ka hokela matla ho WizFi360 mme o romela le ho amohela data ka UART1. 'Me u lokela ho ela hloko lintlha tse' nè.
Setšoantšo sa 6. Reference Schematic
- Seta bocha
Reset potoloho e fana ka ho rala ka potoloho ea RC. WizFi360 reset ka bohona ka matla a boemo bo tlase. Haeba phini ea RESET e laoloa ke potoloho e ka ntle, WizFi360 e tla tsosolosa ha boemo bo le ka tlase ho 2.0V.
Boemo bo tlase bo hloka ho tšoarella ho feta 100µs. - PA0
Potoloho ea PA0 e fana ka ho rala 10k hula-up. PA0 e sebelisoa joalo ka pini ea boot, empa ha ho bonolo hore e sebelisoe ho basebelisi ba tloaelehileng. Pini ena e sebelisoa femeng stage. (Mojule oa tlhahiso) - PA1
Potoloho ea PA1 e fana ka ho rala 10k hula-up. Haeba PA1 e le Tlase bakeng sa metsotsoana e 3, paramethara ea hajoale ea UART1 e fetoha boleng ba kamehla (ka kopo sheba taelo ea AT+UART_CUR ho buka ea litaelo ea WizFi360 AT). - WP
Potoloho ea WP e fana ka ho rala tlhophiso ea basebelisi. O tlameha ho laola phini ena haeba o sebedisa mokgwa wa standby. Haeba phini ena e phahame ka Boemo ba Standby, WizFi360 e tla khutlisetsoa ho mokhoa o tloaelehileng oa ho sebetsa.
3.2. Matla
WizFi360 e hloka tšebeliso ea motlakase o khonang ho fana ka 3.0V ho 3.6V le ho feta 500mA. Hobane WizFi360 e sebetsa ka tloaelo ho tloha ho 3.0V ho ea ho 3.6V, e sebelisa ho fihla ho 230mA ea hona joale ea hang-hang. Bophara ba wiring ha boa lokela ho ba ka tlase ho 30mil.
Matla a tsitsitseng capacitor (100nF) e lokela ho behoa haufi le phini ea VCC.
3.3. UART
Setšoantšo sa 7. UART
- UART1
UART1 ke eona puisano e kholo ea UART. Puisano ea taelo ea AT e ka khoneha ka UART1 mme puisano ea data ea khoneha. - UART0
UART0 ha e fumanehe ho basebelisi ba tloaelehileng. UART ena e sebelisoa femeng stage (Tlhahiso ea Module) mme e etselitsoe baetsi ba firmware ba ka hare ba WizFi360.
3.4. SPI
WizFi360 e tšehetsa mokhoa oa puisano oa SPI. Ha motlakase o buletswe kapa o setwa botjha, Haeba phini ya PB13(SPI_EN) e dula e le tlase, e sebetsa ka mokgwa wa puisano wa SPI.
Setšoantšo sa 8. SPI Interface
3.5. ETC
Seboka sena ke tataiso e eketsehileng ea potoloho bakeng sa ho sebelisa WizFi360. Ha ua tlameha ho boloka lenaneo lena. Empa haeba u e hloka, ua e qapa.
- Taolo ea Phallo ea UART
Haeba o batla ho sebelisa UART Flow Control, o hloka ho rala potoloho joalo ka ha ho bonts'itsoe ho Setšoantšo sa 3. PB9 ke CTS1, PB10 ke RTS1.
Setšoantšo sa 9. Taolo ea Phallo ea UART - UART Level Shifter
UART voltage ho WizFi360 ke 3.3V. Leha ho le joalo, MCU ea hau e kanna ea se be le molumotage ea 3.3V. Haeba ho joalo, o hloka Level Shifter ho hokela WizFi360 ho MCU ea hau. O ka rala potoloho ea Level Shifter ka ho sheba Setšoantšo sa 4. Hokela UART ea MCU ea hau.tage ho VCCIO ho Setšoantšo sa 4.

Sebopeho sa PCB
- Bophara ba lithapo tsa motlakase ha boa lokela ho ba ka tlase ho 30mil.
- Ntle le karolo ea antenna ea WizFi360, karolo e ka tlase ea thebe e ka tlameha ho ba le sefofane sa GND.
Setšoantšo sa 12. GND - Lipalo. 6 le Lipalo. 7 ke 2 antenna placement e ka sebetsang hantle ka ho fetisisa. Re khothaletsa bareki ho khetha e 'ngoe ea mekhoa ena e 2 ho etsa moralo oa sebaka. Bakeng sa mokhoa oa bobeli oa ho beha, antenna ea PCB e lokela ho ba bonyane 5.0mm ho tloha mahlakoreng a mabeli a boto e ka tlaase.
