 # M5StickC DCF77 HAT
 
 Basic hat implementation of a DCF77 receiver for M5StickC-Plus or compatible ESP32 devices. This firmware uses a improvement of Arduino-DCF77 library, it is using events callback to improve the GUI and signal representation.

 ## Device
 
 The current firmware was tested on 77.5KHZ single frequency device. It is the 4 pins version and it was bought here in [Aliexpress](https://www.aliexpress.com/item/1005005254051736.html).
