Review on 🔌 Wireless Module ESP-07 - HiLetgo ESP8266 Serial WIFI, Enhanced for Superior Connectivity by Jeremy Choi

UPDATE 04/25/2019 This is pure junk. Don't waste your time. Receive replacement item from Amazon. Big waste of my time. The first goes into FLASH mode, but does not load the program. I tried two different settings with the same result. Revain, please remove the label "AMAZON CHOICE". Return for a full refund and never buy a HiLetGo product again. UPDATE 4/12/2019 Downgraded to two stars. I ordered two more of these and the first open one didn't work. The program loaded normally but did not run. Tried 4 or 5 settings and different programs. Vain. I'm going back to Amazon for a replacement. this is marked as AMAZON'S CHOICE but seems to lack reproducible quality. 2018 same issue. UPDATE 04/23/2018 Upgrade to 4 stars. I have tested the replacement module that arrived from China today and I am happy to report that it is working properly. If both of the ESP8266 ESP-07 modules I originally ordered worked WITHOUT replacing them, I would give them 5 stars. As a side note, the ESP-07 is a very versatile WiFi module compared to the ESP-01, and by the way, I ordered an additional ESP8266 ESP-07 module from HiLetgo. UPDATE 04/11/2018 Upgrade to 3 stars. will respond to fix the defective item and provide a replacement, which must be pre-tested. As soon as I get it I'll do my own test and if it works I'll update this review again. I ordered two, one worked, one didn't. And it was an Amazon recommended item! I will no longer buy HiLetgo products.
