The receiver decodes the time signals to synchronize the time and date on atomic clocks, which are accurate to within a few microseconds. We designed this product around the awesome receiver chip MAS6180 from Micro Analog Systems (Finland). This module is in particular designed for use with microcontrollers in an operating voltage range of 3.3 or 5V.

The kit includes a high-quality, fine-tuned 77.5kHz antenna with a Q-factor of over 100.

The 77.5kHz Atomic Clock AM Receiver module is compatible with the DCF77 radio station in Mainflingen, Germany, and allows for reception in a radius of about 2000km.
