240m te tawhiti korero
Te kaha tuku 7DBM
Te maramara 2.4G o te kainga SI24R1
2.4G SPI atanga RF kōwae
2Mbps tere hau
He tere ake te tuku tere
Ko te maramara Si24R1
He taonga nui
Tino pai te RF arotautanga patuiro
Te ine tawhiti 240m (marama me te taiao tuwhera)
Ma te whakamahi i te oscillator karaihe ahumahi 16M teitei, te hapa auau o te whenua 10PPM (-40~85 °) ka tirotirohia, ka whakamatauhia o maatau waahanga katoa hei whakarite i te mahi o ia waahanga.
Te painga maramara
Ko te SI24R1 he maramara reo irirangi 2.4GHZ te kaha iti, i hangaia mo nga tono ahokore iti-mana, te awhe auau whakahaere o 2400MHZ-2525MHZ, tautoko mo te 2MBPS, 1MBPS, 250KBPS e toru nga reiti raraunga.
Ko te SI24R1 te mana tuku he +7DBM (ka taea te whakarite), ko te 1UA anake te huri-whakaweto, a ko te whiwhinga ko te -83DBM @2MHZ. I roto i nga tono kaari kaha, kei te moe te maramara i te nuinga o te waa, na reira he iti rawa te whakapau kaha o te SI24R1, a ka taea e koe te whakatutuki neke atu i te 3 tau o te wa mahi.
Ko te SI24R1 e whakamahi ana i te hoahoa o te whare me te tukanga hangahanga, e whakarite ana i te mahi me te utu he tino whakataetae.
Ko te SI24R1 he mea whakaputa mana i te tau 2012, he pai te rite o te hua, te tino pumau, me te utu-utu, a, i riro i a ia te mihi nui mai i nga kaihoko i roto i te waahi whakarite.
