mtunda wolumikizana ndi 240m
Mphamvu yotumizira kwambiri 7DBM
Zapakhomo 2.4G chip SI24R1
2.4G SPI mawonekedwe a RF gawo
2Mbps kuthamanga kwa ndege
Kuthamanga kwachangu kufala
Chithunzi cha Si24R1
Wolemera muzinthu
Zabwino kwambiri RF kukhathamiritsa debugging
Mtunda woyezedwa 240m (malo omveka komanso otseguka)
Pogwiritsa ntchito 16M mafakitale crystal oscillator, zolakwa zafupipafupi padziko lapansi 10PPM (-40 ~ 85 °) ma module athu onse amayesedwa ndikuyesedwa kuti atsimikizire kuti gawo lililonse likugwira ntchito.
Chip mwayi
SI24R1 ndi chilengedwe chochepa mphamvu, mkulu-ntchito 2.4GHZ wailesi ma frequency transceiver chip, opangidwa otsika mphamvu opanda zingwe ntchito, ntchito pafupipafupi osiyanasiyana 2400MHZ-2525MHZ, thandizo kwa 2MBPS, 1MBPS, 250KBPS deta mitengo itatu.
Mphamvu yotumizira ya SI24R1 ndi + 7DBM (yosinthika), njira yozimitsa ndi 1UA yokha, ndipo kumvera kolandira ndi -83DBM @2MHZ. M'mapulogalamu ogwiritsira ntchito makadi, chip chimagona nthawi zambiri, kotero kuti mphamvu zonse za SI24R1 ndizochepa kwambiri ndipo zimatha kukwaniritsa zaka zoposa 3 za nthawi yogwira ntchito.
SI24R1 imagwiritsa ntchito kapangidwe kabwino kapakhomo ndi kupanga, zomwe zimatsimikizira kuti magwiridwe antchito ndi mtengo wake ndi wopikisana kwambiri.
SI24R1 idapangidwa movomerezeka mu 2012, yokhala ndi kusasinthika kwazinthu zabwino, kukhazikika kwapamwamba, komanso kutsika mtengo, ndipo idapambana kuzindikira kwamakasitomala pokonzekera.
