My board has a label showing only D1.
How can I distinguish D1 from D1R2.
It has no label other than just D1.
I've been trying to upload a sketch to WeMos D1 board and failed to upload.
Error message shown by IDE was as follow.
Uploading 226368 bytes from C:\Users\HTOONA~1\AppData\Local\Temp\arduino_build_477861/DBlink1.ino.bin to flash at 0x00000000
An error occurred while uploading the sketch
warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
error: espcomm_upload_mem failed
I want to know how to solve this error.
Please help me.
