Akwụkwọ ntuziaka onye ọrụ ARDUINO CC2541 Bluetooth V4.0 HM-11 BLE
Okwu mmalite
Nke a bụ modul SMD BLE ejiri mee ihe na BLE Bee na Xadow BLE. Ọ dabere na mgbawa TI cc2541, na-eme ka ọnụ ọgụgụ netwọọdụ siri ike wuo ya na ọnụ ahịa ụgwọ ihe dị ala yana dabara nke ukwuu maka sistemụ oriri ike ultralow. Modul ahụ pere mpe ma dịkwa mfe iji, yana ngwa ngwa emepụtara emebere ya, ị nwere ike wulite nkwukọrịta BLE ngwa ngwa site na iwu AT ya. Na-akwado nkwukọrịta BLE na iphone, ipad na gam akporo 4.3.
