Very Versatile Microprocessor with WiFi
These are a good ESP8266 Board. I really like the form factor and the combination of USB for power, programming and serial output. My niggles would be so easily solved! they are...The two on board LEDs are very useful for debugging and having confirmation flashes at specific program points, BUT it would be SO MUCH BETTER if they were DIFFERENT colours. As these are both blue, it is difficult to tell them apart from any distance.The boards have no markings on that match a specific board type in the Arduino IDE which is daft.Apart from that they are great little project work horses. It would be great if they were matched with USB battery power packs that were specified NOT to turn off at low currents as many (phone charger?) types shut down when the current flow is low, as it can be with these boards.

Works perfectly
Really happy, good value for money and we're having fun 😁 works as intended

I had a sense these were the ESPs I was looking for
All seem to work so far.Used with both Arduino IDE and Home assistant

Everything works
Good Consume much less power the the other seller

Excellent little gizmos but poor Wi-Fi range.
I purchased these Wi-Fi modules as I saw a YouTuber using those modules to run Christmas lights around the house,The YouTuber never mention he had problems with its Wi-Fi range but that was in an American house, I struggled to communicate with them unless I was approximately 2 feet away but after I solder an extra bit of wire to the antenna just to see if it improves things but only by a bit.I'm still happy with these modules I'm hoping there may be an improved model out there but I haven't looked yet.

Good, low powered and compact
This is ideal for an IOT device. It is compact meaning it will fit on a standard single breadboard with a single row each side (not like the ESP32's I have which are 1 pin wider and some LoLin 8266's which are 2 pins wider). It is also efficient and doesn't have a power LED so is suitable for battery based applications. Consumes around 1.2mA in deep sleep mode when plugged in via in the on-board regulator.

Easy to use and still small enough for most projects.
I tried programming an esp8266 for hours one day using an Arduino and had nothing but problems.This Dev board fixed all my problems, it made programming a piece of cake and prototyping simple with the numerous connectors to plug into.Also you don't need any additional electronics to step down the 5v vin as this has it all built in.Very happy and a very good price

Where is the free E book?
The description mentions an included free E book which mentions assistance in getting project started. No such book was included in the item I received. Nor was there any documentation to suggest that it could be downloaded.
