Description:
This DCF receiver module plus antenna receives a very accurate timing signal from Germany. The signal can be received up to 1500 km from it's source (City of Frankfurt). The signal is broadcasted on 77.5 kHz with a pulse every second (see also the DCF Wiki page). This module can be used with any micro-controller, like Arduino, to get the right time accurate on the second, plus the actual date.

Specifications:

• Operating Voltage 1.2 .... 3.3 V
• Current < 90 uA
• Receiver frequency 77.5 kHz
• Size of mini circuitboard (without antenna) lxwxh: 15x11x8 mm
