240m ka mamao kamaʻilio
ʻO ka mana hoʻouna kiʻekiʻe 7DBM
Kipa 2.4G kūloko SI24R1
2.4G SPI interface RF module
2Mbps ka holo wikiwiki
ʻOi aku ka wikiwiki o ka hoʻouna ʻana
ʻO ka chip Si24R1
Waiwai waiwai
ʻOi aku ka maikaʻi o ka RF optimization debugging
Ana ka mamao 240m
Ke hoʻohana nei i ke kiʻekiʻe kiʻekiʻe 16M industrial crystal oscillator, frequency error earth 10PPM (-40 ~ 85 °) nānā a hoʻāʻo ʻia kā mākou mau modula āpau e hōʻoia i ka hana o kēlā me kēia module.
ʻO ka pōmaikaʻi chip
ʻO SI24R1 ka mana haʻahaʻa haʻahaʻa, kiʻekiʻe-hana 2.4GHZ radio frequency transceiver chip, i hoʻolālā ʻia no nā noi uila haʻahaʻa haʻahaʻa, ka nui o ka hana ʻana o 2400MHZ-2525MHZ, kākoʻo no 2MBPS, 1MBPS, 250KBPS ʻekolu mau helu data.
ʻO ka SI24R1 ka mana hoʻouna he +7DBM (hiki ke hoʻololi ʻia), ʻo 1UA wale nō ka huli ʻana i kēia manawa, a ʻo ka ʻike loaʻa ʻo -83DBM @2MHZ. Ma nā noi kāleka ikaika, ua hiamoe ka chip i ka hapa nui o ka manawa, no laila, haʻahaʻa loa ka hoʻohana ʻana i ka mana holoʻokoʻa o ka SI24R1 a hiki ke hoʻokō maʻalahi ma mua o 3 mau makahiki o ka manawa hana.
Hoʻohana ka SI24R1 i kahi hoʻolālā hale maʻemaʻe a me ke kaʻina hana hana, e hōʻoiaʻiʻo ana i ka hana a me ke kumu kūʻai.
ʻO SI24R1 i hana nui ʻia i ka makahiki 2012, me ke kūpaʻa huahana maikaʻi, ke kūpaʻa kiʻekiʻe, a me ke kumu kūʻai, a lanakila i ka ʻike lokahi mai nā mea kūʻai aku ma ke kahua o ka hoʻomākaukau.
