Kev sib piv ntawm manufacturers
1. CC2640R2F: Nws yog 7mm * 7mm volumetric thaj hom BLE4.2/5.0 Bluetooth nti launched los ntawm Texas Instruments (TI), nrog ib tug built-in ARM M3 core. Raws li kev hloov kho tshiab ntawm CC2640, CC2640R2F tau txhim kho tag nrho ntawm kev txhawb nqa kev cai thiab kev nco.
2. NRF52832: Nws yog BLE5.0 Bluetooth nti tso tawm los ntawm Nordic Semiconductor (Nordic), nrog rau ARM M4F core built-in. NRF52832 yog qhov hloov kho tshiab ntawm NRF51822. Cov tub ntxhais hloov kho tshiab muaj lub zog siv hluav taws xob ntau dua thiab cov cuab yeej siv hluav taws xob floating.
Kev sib piv ntawm chipset
1. CC2640R2F: Raws li pom hauv daim duab hauv qab no, CC2640R2F muaj peb lub cev cores (CPU). Txhua CPU tuaj yeem siv nws tus kheej lossis sib koom RAM / ROM. Txhua CPU ua nws txoj haujlwm thiab ua haujlwm sib koom tes, ua tiav qhov sib npaug ntawm kev ua haujlwm thiab kev siv hluav taws xob mus rau qhov loj tshaj plaws. Lub luag haujlwm tseem ceeb ntawm Sensor controller yog peripheral control, ADC sampling, SPI kev sib txuas lus, thiab lwm yam. Thaum lub system CPU dormancy, Sensor controller tuaj yeem ua haujlwm ntawm nws tus kheej. Qhov kev tsim no zoo heev txo qhov system CPU wake-up zaus thiab txo hwj chim noj.
2. NRF52832: Raws li pom nyob rau hauv daim duab hauv qab no, nRF52832 yog ib leeg-core SoC, uas txhais tau hais tias tom qab pib BLE raws tu qauv pawg, pawg txheej txheem yog qhov tseem ceeb tshaj plaws. Qhov tseem ceeb ntawm daim ntawv thov kev pab cuam yuav qis dua li cov txheej txheem txheej txheem, thiab kev ua haujlwm yuav raug cuam tshuam rau hauv cov ntawv thov nrog lub sijhawm tiag tiag xws li kev tswj lub cev muaj zog. Hauv kev lag luam khoom siv hnav, xav tau lub zog siv hluav taws xob muaj zog, tab sis hauv lwm yam kev siv, xws li kev sau cov sensor thiab kev ua haujlwm yooj yim kuj yog kev xaiv zoo.

CC2640R2F thiab NRF52832 Kev sib piv ntawm cov yam ntxwv
1. CC2640R2F txhawb nqa BLE4.2 thiab BLE5.0, muaj ib qho built-in 32.768kHz moos siv lead ua oscillator, txhawb lub ntiaj teb no daim ntawv tso cai-dawb ISM2.4GHz zaus band, thiab muaj built-in high-performance thiab low-power Cortex-M3 thiab Cortex-M0 dual-core processors. Muaj peev txheej, 128KB FLASH, 28KB RAM, txhawb nqa 2.0 ~ 3.6V fais fab mov, fais fab mov ntau dua 3.3V tuaj yeem lav qhov kev ua tau zoo tshaj plaws.
2. NRF52832 ib nti, hloov tau yooj yim 2.4GHz multi-protocol SoC, txhawb BLE5.0, zaus band 2.4GHz, 32-ntsis ARM Cortex-M4F processor, muab voltage 3.3V, ntau yam 1.8V ~ 3.6V, 512kB flash nco + 64 kB RAM, cov huab cua txuas tau sib xws nrog nRF24L thiab nRF24AP series.
Tam sim no, Feasycom muaj Bluetooth module FSC-BT630 uas siv NRF52832 chipset, thiab FSC-BT616 siv CC2640R2F chipset.
