I bought this board and have been trying to flash an arduino program written for the esp8266 onto it, but nothing seems to work. I've put the board into flash mode, and when I try to upload the program the blue light on the board blinks 3 times and then the whole thing fails.
I have also tried using the NodeMCU flasher software but that can't find the device either. It just loops at
I have the Silicon Labs CP210x driver installed, and both arduino and NodeMCU flasher can see the port COM 3 which it is connected to, but neither can actually send anything to it. Also I tried installing the CH341 drivers based on what other forums/guides have said to do, but it just says "driver has been preinstalled" and never actually finds a device.
Anyone think that they can help me? Thanks!
