_x005F_x000D_ _x005F_x000D_ _x005F_x000D_ describe: _x005F_x000D_ _x005F_x000D_ DCF receiver module with DCF antenna tuned to signal transmitter DCF77 (Frankfurt 77.5 kHz). The antenna induction signal is sent to the IC for amplification, demodulation, and then identified by the MCU, so that the date and of the timing center can be exactly the same. _x005F_x000D_ _x005F_x000D_ Below you will find important setup and circuit diagrams. _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ Technical Specifications _x005F_x000D_ _x005F_x000D_ Operating voltage: 1.1...3.3 V _x005F_x000D_ _x005F_x000D_ Current consumption: 85 A max _x005F_x000D_ _x005F_x000D_ Receiving frequency: 77.5 KHz _x005F_x000D_ _x005F_x000D_ Board size (without antenna) LxWxH: 22x13.5x1 mm _x005F_x000D_ _x005F_x000D_ Antenna quality: Lx: 60x10mm _x005F_x000D_ _x005F_x000D_ Scope of delivery: 1 piece _x005F_x000D_ _x005F_x000D_ DCF receiver module with antenna _x005F_x000D_ _x005F_x000D_ connect: _x005F_x000D_ _x005F_x000D_ Ground = Pin G _x005F_x000D_ _x005F_x000D_ Operating Voltage = Pin V _x005F_x000D_ _x005F_x000D_ data = pin T _x005F_x000D_ _x005F_x000D_ Power On/Off = Pin P1 _x005F_x000D_ _x005F_x000D_ Important note: _x005F_x000D_ _x005F_x000D_ PIN P1 is an on/off switch and must be set to logic low. _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ The package includes: _x005F_x000D_ _x005F_x000D_ 1*Receiver module _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ _x005F_x000D_
