Hoʻohālikelike o nā mea hana
1. CC2640R2F: He 7mm * 7mm volumetric patch type BLE4.2/5.0 Bluetooth chip i hoʻokumu ʻia e Texas Instruments (TI), me kahi kumu ARM M3 i kūkulu ʻia. Ma ke ʻano he mana hou o CC2640, ua hoʻomaikaʻi maikaʻi ʻia ʻo CC2640R2F ma ke ʻano o ke kākoʻo ʻana i nā protocols a me ka hoʻomanaʻo.
2. NRF52832: He puʻupuʻu Bluetooth BLE5.0 i hoʻokuʻu ʻia e Nordic Semiconductor (Nordic), me kahi kumu ARM M4F i kūkulu ʻia. ʻO NRF52832 kahi mana hou o NRF51822. ʻOi aku ka ikaika o ka mana helu a me ka ʻenehana helu floating-point.
Hoʻohālikelike o chipset
1. CC2640R2F: E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, CC2640R2F aia ʻekolu core kino (CPU). Hiki ke hoʻohana kūʻokoʻa i kēlā me kēia CPU a i ʻole kaʻana like RAM/ROM. Hoʻokō kēlā me kēia CPU i kāna mau hana ponoʻī a hana pū me ka hoʻokō ʻana i kahi kaulike ma waena o ka hana a me ka hoʻohana ʻana i ka mana i ka nui loa. ʻO nā hana nui o ka Sensor controller ka mana peripheral, ADC sampling, SPI kamaʻilio, a me nā mea ʻē aʻe. Hoʻemi nui kēia hoʻolālā i ka ʻōnaehana CPU ala ala pinepine a hoʻemi i ka hoʻohana mana.
2. NRF52832: E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, ʻo nRF52832 kahi SoC hoʻokahi-core, ʻo ia hoʻi ma hope o ka hoʻomaka ʻana i ka BLE protocol stack, ʻo ka protocol stack ka mea nui loa. ʻOi aku ka haʻahaʻa o ka papahana noi ma mua o ka waihona protocol, a hiki ke hoʻopili ʻia ka hana i nā noi me nā koi manawa maoli kiʻekiʻe e like me ka mana kaʻa. I ka mākeke mea hiki ke hoʻohana ʻia, pono ka mana computing ikaika, akā i nā noi ʻē aʻe, e like me ka hōʻiliʻili sensor a me ka hana maʻalahi he mau koho maikaʻi nō hoʻi.

CC2640R2F a me NRF52832 Hoʻohālikelike o nā hiʻohiʻona
1. Kākoʻo ʻo CC2640R2F i ka BLE4.2 a me BLE5.0, he 32.768kHz uaki oscillator i kūkulu ʻia, kākoʻo i ka honua holoʻokoʻa laikini ISM2.4GHz alapine, a ua kūkulu ʻia i ka hana kiʻekiʻe a me ka mana haʻahaʻa Cortex-M3 a me ka Cortex-M0 kaʻina hana ʻelua. Nui nā kumuwaiwai, 128KB FLASH, 28KB RAM, kākoʻo 2.0 ~ 3.6V mana lako, lako mana ʻoi aku ma mua o 3.3V hiki ke hōʻoia i ka hana maikaʻi loa.
2. NRF52832 puʻupuʻu hoʻokahi, hiki ke maʻalahi 2.4GHz multi-protocol SoC, kākoʻo iā BLE5.0, alapine alapine 2.4GHz, 32-bit ARM Cortex-M4F kaʻina, hāʻawi uila 3.3V, laulā 1.8V ~ 3.6V, 512kB flash memory + 64kB RAM , kūpono ka loulou ea me nRF24L a me nRF24AP series.
I kēia manawa, loaʻa iā Feasycom ka module Bluetooth FSC-BT630 e hoʻohana ana i ka chipset NRF52832, a ua hoʻohana ʻo FSC-BT616 i ka chipset CC2640R2F.
