●  Adopt EFM32ZG108F16 + Silicon Labs company Si4455 program

        ●  This test board can be used for communication demonstration with Silabs 4455-LED-434 demo board

        ● The  whole machine is powered by button battery (standard: CR3032), low power consumption mode:

           -The  whole machine sleeps for 1.2s, and the dormant whole machine current is about 0.9uA; wake up RF reception; the 
             whole machine wakes up to work for 2.95ms, so it works periodically.

        ●  RF adopts Si4455 scheme, the physical layer is defined as follows:

           -  Frequency 433.000000MHZ

           -  offset 200KHZ

           -  Modulation 2-FSK

           -  communication speed 250KHZ

           -  using software solutions whitening data, CRC check process

           -  synchronization word format: 0X33333333

           -  receiving variable length data packets <= 64 bytes

        ●  Small size, easy to carry, convenient for users to evaluate and test
