Hi Cefn,
Just received another couple of Wemos D1 Mini and Arduino layout boards from Aliexpress and noted that both will not flash. I've run the following to ID them for you.
esptool.py --port /dev/ttyUSB0 flash_id
==WEMOS D1 Mini Output==
Detecting chip type... ESP8266
Chip is ESP8266EX
Features: WiFi
Manufacturer: c8
Device: 4016
Detected flash size: 4MB
==Wemos D1 Arduino Layout Output==
Detecting chip type... ESP8266
Chip is ESP8266EX
Features: WiFi
Manufacturer: ef
Device: 4016
Detected flash size: 4MB
Is there any chance that these can be added?
Cheers
Les
