D1 Mini Micro SD TF Card Shield WeMos
This microSD shield is designed to be used with the WeMos mini & mini Pro ESP8266-based development boards. Adding this shield to your WeMos mini development board provides it with the ability to store data in a microSD card. Included with the shield is a set of header pins that can be soldered to the shield to allow it to be easily inserted and removed from the D1 Mini.
Although this module is intended for use with the Wemos D1 Mini and Mini Pro development boards it can of course also be used as a standalone Data logger module.
