Imiyalelo yeMveliso
Imodyuli ye-MK14 nRF52805 imodyuli yexabiso eliphantsi kakhulu yeBluetooth eyilwe nguMOKOsmart isebenzisa iNordic Bluetooth 5.2SoC-nRF52805 yamva nje.
IMB14 yeBluetooth 5.2 Imodyuli inobungakanani obuncinci be-12.1mmx8.9mm, Uyilo lwe-RF oluye lwahlengahlengiswa ngobuchule ziinjineli zeMOKOsmart, kwaye inokubekwa ngokukhawuleza kwi-PCB yomsebenzisi. Uchungechunge lweMK14 lunenkxaso ye-multi-protocol ye-Bluetooth Low Energy kunye ne-2.4GHz, irediyo yayo inokubonelela ukuya kuthi ga kwi-4dBm ukuphuma kwamandla kunye -97dBm uvakalelo (1 Mbps iBluetooth yamandla asezantsi), ikhonkco kuhlahlo-lwabiwo mali lwe-101dBm, nge 2 I-Mbps yamandla asezantsi e-Bluetooth kwimodi ephezulu kunye nokukhethwa kwesitishi sealgorithm #2 (CSA #2) umsebenzi.
I-MK14 uthotho lwe-Bluetooth nRF52805 yemodyuli ineemodeli ezimbini ezahlukeneyo-iMK14A kunye neMK14B
IMK14A
I-MK14A idibanisa intsebenzo ephezulu ye-PCB
IMK14B
IMK14B isebenzisa isinxibelelanisi se-u.FL kwaye ifuna i-eriyali yangaphandle.
