 ## Version history
+#### v0.9.250
+- added support for DS1307 or DS3231 RTC module (you need to install the RTCLib library in the library manager)
+- setup
+```
+#define RTC_MODULE	DS3231	/* or DS1307	*/
+#define RTC_SDA       <pin>
+#define RTC_SCL       <pin>
+```
+
 #### v0.9.242
 - fixed a hang bug when scrolling through an SD playlist with an encoder in configurations with VS1053B
 - fixed a hang bug when quickly switching SD / WEB modes from the WEB interface in configurations with VS1053B
