9. Intelligentdatacontroland no anyextra programsrequired
Evenforhalfduplexcommunication, no anyexcessiveprogramsrequired. All RFsystem
datasending/receivingand other On-the-Flyconversion and controlare performedby
HAC-UM transceiversautomatically.
10. Lower power consumption &Sleep function
With+5Vpower,thereceivecurrentisless than32mA,thetransmitcurrentisless than
42mA, and thesleepingcurrentis less than 5µA.
With+3.3Vpower,thereceivecurrentisless than26mA,thetransmit currentisless than
36mA, and thesleepingcurrentis less than 5µA.
11. High reliability, small and light
Byusingmonolithicradio-frequencyintegratedcircuit and single-chipMCU,the
transceivers haveless peripheralcircuits, high reliability, and lowfailure rate.
12. More options ofconfigurableantennas foruser differentapplications.
