I think I have the ESP8266 SkyWeather board (2 grove connectors) ID 0011-021916-01.
Are any of the JP17 or JP18 pins available to use as GPIO input? If so are they 3.3V or 5V compatible?
Do the JP17 labels 12, 13, 14, 16 indicate the pin number to use in code? GPIO16 is bootstrap so will not use. The rest if GPIO are SPI which I don't think is used? I do not have a screen and its not connected to RPI.
What about JP18 labels #0, #2, #4, #5? If GPIO these look to be used by SDA, SCL, and during bootstrap so will not use.
Otherwise could I use the ADC inputs A1-A3? It looks like only A0 is used? If so are they 3.3V or 5V compatible?
Otherwise I will use a I2C grove GPIO expander but I want to keep power draw low as its solar powered.
Thanks

The PDF link in above message is not for the board I mentioned but it provided enough info for me to find the correct WeatherPlus Specifications PDF I urge Switchdoc to use unique identifiable names for all product and versions, keeping legacy documents available, so that applicable info can be easily found.
This page has formatting errors but links to WeatherPlus_Specification PDFThis PDF indicated that GPIO13 is available if the Thunderboard is not connected. All other GPIO pins are used and not available. I was able to use GPIO13 as input. I was also able to use PCF8574 IO expander via I2C but removed it since GPIO13 was available in my case. |

Hi, post a picture so I know what you have. I'll find the spec.
Sounds like you solved the GPIO problem. It's a busy board.

Hi, post a picture so I know what you have. I'll find the spec. Thanks for the follow up. My board, with ID 0011-021916-01, looks exactly like the WeatherPlus board shown on the WeatherPlus page. My confusion was that I bought the "OurWeather Complete Kit" that turns out to use the "WeatherPlus" board so I was looking in the wrong place for info. As I said I have it working and found all the info I need.
