Te whakataurite o nga kaihanga
1. CC2640R2F: Ko te 7mm * 7mm momo papaki volumetric BLE4.2 / 5.0 maramara Nihokikorangi i whakarewahia e Texas Instruments (TI), me te ARM M3 matua i hangaia. Hei putanga whakahou o CC2640, kua tino pai ake a CC2640R2F i runga i nga tikanga tautoko me te mahara.
2. NRF52832: He maramara Nihokikorangi BLE5.0 i whakarewahia e Nordic Semiconductor (Nordic), me te ARM M4F matua i hangaia. Ko te NRF52832 he putanga whakahou o NRF51822. He kaha ake te mana rorohiko me te hangarau rorohiko ira-rewa.
Whakatauritenga o chipset
1. CC2640R2F: E whakaatu ana i te ahua i raro nei, kei roto i te CC2640R2F e toru nga uho tinana(PTM). Ka taea te whakamahi takitahi me te tiri RAM/ROM ranei. Ka mahia e ia PTM ana ake mahi me te mahi tahi, ka eke ki te taurite i waenga i nga mahi me te whakapau hiko ki te tino nui. Ko nga mahi matua o te kaiwhakahaere Sensor ko te mana peripheral, te ADC sampling, te whakawhitiwhiti SPI, me etahi atu I te wa e moe ana te punaha CPU, ka taea e te kaiwhakahaere Sensor te mahi takitahi. Ko tenei hoahoa ka tino whakaiti i te auau oho-ake PTM me te whakaiti i te kohi hiko.
2. NRF52832: E whakaatu ana i te ahua i raro nei, ko te nRF52832 he SoC-matua kotahi, ko te tikanga i muri i te tiimata o te kawa kawa BLE, ko te puranga kawa kei te tino kaupapa. Ko te kaupapa matua o te hotaka tono ka iti ake i tera o te kawa kawa, ka raru pea te mahinga i roto i nga tono me nga whakaritenga wa-waahi nui penei i te whakahaere motuka. I roto i te maakete taputapu kakahu, me kaha ake te mana rorohiko, engari i etahi atu tono, penei i te kohinga puoro me te tukatuka ngawari he whiringa pai.

CC2640R2F me NRF52832 Te whakataurite o nga ahuatanga
1. Kei te tautoko a CC2640R2F i te BLE4.2 me te BLE5.0, he oscillator karaihe karaka 32.768kHz kua hangaia, e tautoko ana i te roopu auau ISM2.4GHz kore raihana o te ao, a kua hanga-i roto i nga mahi teitei me te iti-kaha Cortex-M3 me Cortex-M0 pūtukatuka rua-matua. He maha nga rauemi, 128KB FLASH, 28KB RAM, tautoko 2.0～3.6V te hiko hiko, te hiko nui ake i te 3.3V ka taea te whakarite i te mahi pai.
2. NRF52832 maramara kotahi, tino ngawari 2.4GHz maha-kawa SoC, tautoko BLE5.0, auau 2.4GHz, 32-bit ARM Cortex-M4F pūtukatuka, supply ngaohiko 3.3V, awhe 1.8V ~ 3.6V, 512kB mahara flash + 64kB RAM , he hototahi te hononga hau ki nga raupapa nRF24L me nRF24AP.
I tenei wa, kei a Feasycom te waahanga Nihokikorangi FSC-BT630 e whakamahi ana i te NRF52832 chipset, me te FSC-BT616 kei te whakamahi CC2640R2F chipset.
