Hua kua mutuview
JS7688 kōwae poari matua ko te kōwae WIFI i runga i MTK (Mediatek) MT7688AN SOC kaupapa maramara whakarewahia e Hangzhou Jotale Technology Co., LTD.CPU auau ki runga ki te 580MHz, onboard kōwhiringa 64MB DDR2 RAM/8MB Flash, 128MB DDR2 RAM/16MB Flash, 256MB DDR2 RAM / 32MB Flash whirihoranga, 150M WIFI, waho arahi USB 2.0 Kaihautū, GPIO, UART, I2S, I2C, atanga kāri SD, SPI, PWM, atanga Ethernet, atanga antenna WIFI, etc.
He iti te rahi o tenei waahanga, he iti te kohi hiko, he iti te wera, he pumau i roto i te WIFI me te mahi tuku tauranga whatunga. Ko te whakahaere i te punaha OpenWRT (Linux) ka taea te whakahaere mo te wa roa. Ko te ara iahiko peripheral o te kōwae he tino ngawari. Me taapiri noa he hiko 3.3V DC hei tiimata i te punaha ka taea te whakahaere ma te WIFI. Ko te whakamahi i te hononga ngira whakakikoruatia koura ranei stamp hononga poka e taea e tino pūmau i runga i te pereti raro.
Ka taea te whakamahi i roto i nga tono maha penei i nga kaainga atamai, nga kamera IP, VOIP, rererangi pupuhi mamao, nga punaha aroturuki mamao, ngawari WEB tūmau whatunga, tūmau FTP māmā, tango mamao, waka matakite mamao, me ētahi atu. Ka tino whakawhanakehia e matou te papahoa papa mo tenei poari matua, te hanganga JS7688 poari whanaketanga, me te whakarato i nga korero whakawhanaketanga taipitopito, te whakahaere i te kaiwhakamahi ki te ako, te whanaketanga, nga korero. tomo koa www.jotale.com webpae ki view.

2.2.3 Tohutohu mōkihi
Tuhipoka: “JS7688_convert_board_xxxx.PcbLib” (ko XXXX te nama putanga) JS7688 kōwae PCB mōkihi kei te whare pukapuka kei roto.
Hoahoa tohutoro papapapa
3.1 Iahiko hiko
Ko te tuku hiko voltagKo te e o te papa kaute he 3.3V me te 185mA te waa toharite. Kia mau ai te mahi o te papa kaute, me rahuitia he 500mA o naianei mo te waahanga (i runga i te tono tuturu). Ko te ahua i raro nei ko te hoahoa o te 3.3V hiko hiko o te papaapapa JS7628
MP1482 pūmau maramara supply mana kei te whakamahia i roto i te ahua o runga, e taea te tae 2A putanga nāianei. Ka taea e nga kaiwhakamahi te whiriwhiri mehemea ka whakamahi i tenei tauira, kaore ranei i runga i te ahua o te ahuatanga. Kaore i te tūtohutia ki te whakamahi i te hiko "LDO chip", penei i te AMS1117, ahakoa he maamaa te hoahoa ara iahiko o tenei momo maramara, he iti rawa te kaha o te mahi o naianei, me te wera nui, he ngawari ki te whakaputa i te punaha. hiko tuku hikotage, na reira ka arahi ki te koretake o te punaha.
3.2 Mo nga tauranga GPIO
Ko te INPUT me te putanga voltage o te titi GPIO o MT7628/MT7688 he 3.3V. Ko etahi titi GPIO he kumea, he kumea-iho ranei i roto i te waahanga hei whirihora i te punaha mo te whakaoho MT7628/MT7688. Kia mahara ka timata te poari, kaua te titi GPIO e tapaina ana "humea ki runga" i roto i te "whakataki titi" kia kaua e pehia ki waho ki raro ki te taumata iti, me te titi GPIO e tapaina ana "humea-iho" kaua e pehia ki waho. ki te piki ki te taumata teitei, ki te kore, ka kore e taea e te punaha te mahi noa. Ka taea te whakamahi etahi atu GPIO kia rite ki te tauranga GPIO noa.
3.3 Pūnaha iti o te poari matua
Me hono noa te kaiwhakamahi i nga titi "GND" me "VDD3V3" o te poari matua ki te tuku hiko ki te papa kaute, ka hono i nga titi matua e toru "WDT_RST_N", "EPHY_LED2_N_JTMS" me "WLED_N" me te 10K te kume-iho parenga ki te te whenua, ka taea e te punaha te mahi noa. Ko tenei waahanga kaore e hiahia ki te taapiri i nga totohu wera, engari ki te whakapai ake i te pai o te tohanga wera o te punaha, me ngana ki te hono i nga titi "GND" katoa o te kōwae ki te pereti raro "GND" titi i hangaia e te kaipanui, na. kia pai ake te painga o te wera. Ko etahi atu titi, penei i te tauranga rangatū patuiro, te tauranga whatunga, me etahi atu, ka taea te taapiri kia rite ki nga hiahia o te kaiwhakamahi. Mena kaore koe e hiahia ana, kaua e hono atu. Ka taea e nga kaipanui te korero ki te "JS7628_base_board_xxxxx.pdf"(ko te xxxxx te nama putanga) te raarangi papa papa mo te hoahoa.
Te pāmahana i te wa e rere ana
Mena ka hiahia te kaihoko ki te hoahoa i te papaapapa me te JS7688 stamp kōwae putanga kōhao i roto i te mihini reflow fehokotaki'anga, whakarongo ki te reflow fehokotaki'anga tihi emperature e kore e nui ake 240 ℃, ki te kore, kia meinga te reira kino ki te JS7688 stamp kōwae poka.

Tauākī FCC
Ka tutuki tenei taputapu ki te wahanga 15 o nga Ture FCC. Ko te mahi kei raro i nga tikanga e rua e whai ake nei: (1) Kare pea tenei taputapu e whakararu kino, a (2) me whakaae tenei taputapu ki nga pokanoa ka tae mai, tae atu ki te pokanoa ka puta he mahi kino. Ko nga huringa me nga whakarereketanga kaore i tino whakaaehia e te roopu kawenga mo te hanganga ture ka whakakorehia te mana o te kaiwhakamahi ki te whakahaere i nga taputapu.
Tuhipoka: Kua whakamatauria enei taputapu, kua kitea e u ana ki nga rohe mo tetahi taputapu matihiko Class B, i runga i te wahanga 15 o nga Ture FCC. I hoahoatia enei rohe ki te whakarato i te whakamarumaru tika mai i nga pokanoa kino i roto i te whakaurunga whare. Ka mahia e tenei taputapu nga whakamahinga ka taea e ia te whakaputa i te hiko auau reo irirangi, a, ki te kore e whakauruhia, ka whakamahia i runga i nga tohutohu, ka raru pea nga korero reo irirangi. Heoi, karekau he taurangi ka kore e puta he pokanoa ki tetahi whakaurunga. Mena ka raru nga taputapu i runga i te reo irirangi, pouaka whakaata ranei, ka taea te whakatau ma te whakaweto i nga taputapu, ka akiakihia te kaiwhakamahi ki te ngana ki te whakatika i te pokanoa ma te kotahi, neke atu ranei o nga tikanga e whai ake nei:
- Whakahoahoa, nukuhia ranei te antenna whiwhi.
- Whakanuia te wehenga i waenga i te taputapu me te kaiwhiwhi.
- Honoa te taputapu ki tetahi putanga i runga i te ara iahiko rereke mai i tera e honoa ana te kaiwhiwhi.
- Korero atu ki te kaihoko, ki tetahi tohunga hangarau reo irirangi/TV mo te awhina.
Ko te WIFI Module i hangaia kia rite ki te korero a FCC. Ko te ID FCC ko 2AXEE-JS7688. Ko te punaha kaihautu e whakamahi ana i te WIFI Module me whai tapanga e tohu ana kei roto te FCC o te modular
ID:2AXEE-JS7688. Kaua e whakaurua tenei waahanga reo irirangi ki te whakakotahi me te mahi i te wa kotahi me etahi atu reo irirangi i roto i te punaha kaihautu ka hiahiatia etahi atu whakamatautau me te whakamana taputapu hei mahi i te wa kotahi me etahi atu reo irirangi.
I hangaia te kōwae WIFI mo te hoahoa PCB kiato. Me whakauru me te whakahaere me te kaihautu me etahi atu tawhiti iti o te 20 henimita i waenga i te radiator me to tinana. Hei ū ki nga ture FCC e whakawhāiti ana i te mana whakaputa RF morahi me te rongo tangata ki te iraruke RF, ko te nui o te whiwhinga antenna tae atu ki te ngaronga taura i roto i te ahuatanga pukoro-anake me kaua e neke ake i te 5dBi i te roopu 2.4G. Ko te WIFI Module me ona antenna me kaua e noho tahi, e mahi ranei i roto
hono atu ki tetahi atu kaikawe, antenna ranei i roto i tetahi taputapu manaaki.
Ka whakauruhia e tenei waahanga he atanga antenna IPEX, me hoko te kaiwhakamahi me te whakauru i te antenna kia rite ki nga tohutohu.
Panui ki te kaiwhakauru OEM
Ko te waahanga WIFI kua hangaia mo te hoahoa PCB kiato.Me whakauru me te whakahaere me te pona. Ka taea e OEM te whakauru i te kōwae ki roto i te kaihautu ma te tauranga USB o te kōwae, engari me tohu ko te tauranga swipe o te kōwae me whakauru tika ki runga i te mata hei whakarite i te mahi noa o te mahi NFC.
Kei roto i te pukapuka-whakamutunga nga korero mo te ture/whakatupato pera me te whakaatu i tenei pukapuka. Ko te kaiwhakauru OEM te kawenga mo te whakamatautau i a raatau hua-mutunga mo etahi atu whakaritenga tautukunga e hiahiatia ana me tenei waahanga kua whakauruhia.
Me whakauru ngaio te taputapu Ko te tikanga kaore e whakamahia mo te marea. Ko te hononga kei roto i te kopae tuku ka taea te uru atu ma te wetewete o te kaiwhakawhiti kaore e hiahiatia ana, kaore te kaiwhakamahi e uru ki te hono. Me whakahaere te whakaurunga. Me whakangungu motuhake tenei taputapu ki te Wāhanga 15, Wāhanga C, Wāhanga 15.247 o nga Ture FCC.
