Computersmith64 Well-Known Member Licensed User Longtime User May 27, 2017 #1 Hi - I'm looking for some help with connecting a MicroSD shield to a WeMos D1 R2. I thought the correct pinout was: D1 -> SD ----------------- SS/D8 - D8 MOSI/D7 - D7 MISO/D6 - D6 SCK/D5 - D5 3V3 - 3V3 GND - GND However now the board that I connected to seems to be toast. On bootup the SCK LED comes on, but then goes out & stays out & I can't seem to successfully connect to the board via the USB cable. Any ideas? Thanks - Colin.
