Nkọwa ọrụ:
PmodWiFi na-enye nkwado IEEE 802.11b/g/n maka ngwa agbakwunyere na ọnụego data nke 1 na 2Mbps. Emebere ya maka iji ya na ezinụlọ Microchip microcontroller (PIC18, PIC24, dsPIC33, na PIC32) yana Microchip TCP/IP Stack.
1.1 interface:
Isi nzikọrịta ozi nwere PmodWiFi bụ ụgbọ ala SPI. PmodWiFi na-enyekwa ntụtụ nkwụsịtụ dị ala na-arụ ọrụ (~INT) yana ntụtụ RST maka nrụpụta ngwaike.

Ịnye ọkụ:
PmodWiFi chọrọ 2.7V-3.6V ọkọnọ voltage. A 3.3V ike ọkọnọ voltage dị na bọọdụ sistemụ Digịlent niile wee nye ya dịka akụkụ nke ọkọlọtọ 12-waya Pmod interface. Gbaa mbọ hụ na a na-agbapụ bọọdụ sistemụ iji nye 3.3V na modul tupu itinye ike na bọọdụ ahụ.
Maka ozi ndị ọzọ, rụtụ aka na mpempe akwụkwọ data MRF24WB0MA dị na Microchip's websaịtị.
gafereview
PmodWiFi na-enye ohere Wi-Fi site na Microchip® MRF24WG0MA Wi-Fi™ redio transceiver modul. Ndị ọrụ nwere ike ịkọrọ IEEE 802.11g mgbawa nnabata site na SPI wee nweta ọnụego data ruru 54 Mbps.
Atụmatụ gụnyere:
- IEEE 802.11 transceiver RF kwekọrọ
- Zipụ data na 1 na 2 Mbps ruo 400 m
- Adreesị MAC pụrụ iche ahaziri iche
- Igwe PCB agbakwunyere
- Asambodo ụkpụrụ redio maka US, Canada, Europe na Japan
- Asambodo Wi-Fi
- Obere PCB maka atụmatụ mgbanwe 1.7" × 1.0" (4.3 cm × 2.0 cm)
- Njikọ Pmod 12-pin nwere interface SPI
- Na-agbaso nkọwapụta Interface Pmod Digilent 2A
- Ọbá akwụkwọ dị na etiti akụrụngwa

Interface
Isi nzikọrịta ozi nwere PmodWiFi bụ ụgbọ ala SPI. Ntụtụ RST na-enye onye ọbịa ihe nrụpụta ngwaike dị ala na-arụ ọrụ maka PmodWiFi. PmodWiFi na-enyekwa ntụtụ nkwụsịtụ obere ọrụ (~INT), nke PmodWifi na-ekwu na ọ dị ala mgbe data dị maka ngwaọrụ nnabata. The ~INT ahịrị na-de-kwadoro elu mgbe nnyefe data zuru ezu. Ọsọ SPI SCK nwere ike iru 25 MHz.
