Kuyerekeza kwa opanga
1. CC2640R2F: Ndi 7mm * 7mm volumetric patch mtundu wa BLE4.2/5.0 Bluetooth chip yoyambitsidwa ndi Texas Instruments (TI), yokhala ndi ARM M3 core. Monga mtundu wosinthidwa wa CC2640, CC2640R2F yasinthidwa bwino potengera ma protocol ndi kukumbukira.
2. NRF52832: Ndi chipangizo cha Bluetooth cha BLE5.0 chomwe chinayambitsidwa ndi Nordic Semiconductor (Nordic), chokhala ndi ARM M4F core. NRF52832 ndi mtundu wokwezeka wa NRF51822. Pachimake chokwezedwa chili ndi mphamvu zamakompyuta zamphamvu kwambiri komanso ukadaulo wamakompyuta woyandama.
Kufananiza kwa chipset
1. CC2640R2F: Monga momwe chithunzi chili pansipa, CC2640R2F ili ndi ma cores atatu (CPU). CPU iliyonse imatha kugwiritsidwa ntchito palokha kapena kugawana RAM/ROM. CPU iliyonse imagwira ntchito yakeyake ndikugwira ntchito mogwirizana, kukwaniritsa mgwirizano pakati pa magwiridwe antchito ndi kugwiritsa ntchito mphamvu kwambiri. Ntchito zazikulu za Sensor controller ndi zotumphukira, ADC sampling, SPI kulankhulana, etc. Pamene dongosolo CPU dormancy, wolamulira Sensor akhoza kugwira ntchito paokha. Kapangidwe kameneka kamachepetsa kwambiri ma frequency a CPU kudzuka ndikuchepetsa kugwiritsa ntchito mphamvu.
2. NRF52832: Monga momwe tawonetsera m'chithunzichi, nRF52832 ndi SoC imodzi yokha, zomwe zikutanthauza kuti mutatha kuyambitsa stack ya BLE protocol, stack protocol ndi yofunika kwambiri. Chofunika kwambiri cha pulogalamu yogwiritsira ntchito chidzakhala chochepa kusiyana ndi chiwerengero cha protocol, ndipo magwiridwe antchito angakhudzidwe ndi mapulogalamu omwe ali ndi zofunikira zenizeni zenizeni monga kuyendetsa galimoto. Pamsika wamakina ovala, mphamvu yamphamvu yamakompyuta imafunika, koma muzogwiritsa ntchito zina, monga kusonkhanitsa sensa ndi kukonza kosavuta ndi zosankha zabwino.

CC2640R2F ndi NRF52832 Kuyerekeza kwa mawonekedwe
1. CC2640R2F imathandizira BLE4.2 ndi BLE5.0, ili ndi oscillator ya wotchi ya 32.768kHz, imathandizira gulu la ma frequency la ISM2.4GHz lapadziko lonse lapansi, ndipo ili ndi mawonekedwe apamwamba komanso otsika mphamvu ya Cortex-M3. ndi Cortex-M0 dual-core processors. Zinthu zambiri, 128KB FLASH, 28KB RAM, kuthandizira 2.0 ~ 3.6V magetsi, magetsi ochulukirapo kuposa 3.3V angatsimikizire kugwira ntchito bwino.
2. NRF52832 single chip, yosinthika kwambiri 2.4GHz multi-protocol SoC, kuthandizira BLE5.0, frequency band 2.4GHz, 32-bit ARM Cortex-M4F purosesa, magetsi operekera 3.3V, osiyanasiyana 1.8V ~ 3.6V, 512kB flash memory + 64kB RAM , ulalo wa mpweya umagwirizana ndi nRF24L ndi nRF24AP mndandanda.
Pakali pano, Feasycom ali Bluetooth gawo FSC-BT630 amene amagwiritsa NRF52832 chipset, ndi FSC-BT616 ntchito CC2640R2F chipset.
