Popis
Sériový bluetooth modul s technológiou BLE. Modul má veľmi kompaktné rozmery a nízku spotrebu, preto je vhodný pre projekty napájané z batérie alebo kde je obmedzenie priestoru.
Modul sa ovláda setom AT príkazov a funguje bez problémovo aj s modernými smartfónmi – na obchod play je množstvo aplikácií umožňujúcich pripojenie mobilov ku bluetooth modulu.
Pre viac informácií odporúčame preštudovať video návod alebo datasheet.
