DS1307 Mini RTC Micro SD Module WEMOS D1
The Realtime clock and microSD shield was created for use with the WeMos mini and mini Pro ESP8266 development boards. By attaching it to your DS1307 Mini RTC Micro SD Module WEMOS D1 board, you can easily save data onto a microSD card and utilize the onboard RTC for keeping track of time.
The shield comes with a set of header pins that can be soldered on if desired. This allows for easy insertion and removal of the shield from the D1 mini. Additionally, the stackable headers allow users to stack multiple shields on top of this microSD Shield.
While its primary purpose is for Wemos development boards, this module can also function as a standalone Data logger module.
