Neat card, useful functionality but zero documentation or support
The card arrived with zero documentation and I was unable to find any online information either for the Industry Park CJMCU-14 or the onboard AESP-14 wi-fi module.I discovered the ESP-14 is no longer supported by Ai-Thinker on their website (which returned "no result found" when I did a search on this part). Eventually I found a couple of reviews - apparently the ESP-14 is actually an ESP-12 married to an 8 bit micro-controller called the STM8S. The reason for this odd pairing (the ESP-12 contains a powerful 32 bit processor) appears to be all about power conservation. In operation the wi-fi module would be turned off until needed - the STM8S would make that decision.I could not find a website for Industry Park or the CJMCU-14 (the part number stamped on the back of the unit). I could not find any online support whatsoever for this product. Consequently, and unless the manufacturer chooses to offer some documentation on this card, I STRONGLY advise against buying this product.

This review is for the HDC1080 Temp/Hum Sensor
As one other reviewer pointed out... there is no documentation anywhere to be had, Not even big enough for a paper weight in a light breeze.
