HiLetgo Internet Development Wireless Micropython Networking Products Review

this is my first time experimenting with the esp8266 module. I have ordered various esp8266-12E modules from HiLetgo. It took me a month and a half to get to my doorstep from China but again I live in Colombia parts arrived in perfect condition and sealed in an antistatic bag all modules worked the only thing I had to figure out was how to flash them actually it's not hard to figure it out its not that hard linux has native USB serial support UART bridge controller (Ubuntu) Windows requires…

Update: They said they will return the money soon, I'm waiting. NO. They wanted me to change my rating first. DOUBLE NO. Revain Guarantee Refund A to Z. I love Revain. WiFi didn't work. HORRIBLE design, see attached picture. I was offered to download the software in lieu of a refund or replacement. I bought this module from another manufacturer and it worked great.

I have to say this is a great board and it works well with Arduino. First, my only problem is that the pin numbers are wrong / use the same format as the Arduino. After some digging I found this on Github showing the difference. ;static constant8_t D5 = 14;static constant8_t D6 = 12;static constant8_t D7 = 13;static constant8_t D8 = 15;static constant8_t D9 = 3;static constant8_t D10 = 1;

Initially I had trouble running any code until I tried selecting a higher clock speed (160MHz versus 80). I was able to boot, download spiffs, and even connect to Wi-Fi with no issues, but it was excruciatingly slow and the settings were never saved. Before I knew it, one had already bitten the dust (nothing connected, only 5V from USB. Got REALLY hot. I thought one was kinda my fault so I threw it away. Same thing happened to the other two after a few days. Disappointing .

Good board. Good for prototyping and labs. I didn't want to mess around with LUA or Micropython - I just used the Arduino IDE, which I assume is C++. Also, I had to try a few micro-USB cables before I could solve what seemed to be a common problem. However, I would definitely not recommend it for continuous battery-powered use where deep sleep is at stake. In deep sleep, it consumes 9.5mA of current. This will drain a 14650 battery in less than a week. I know there are ways to reduce it by…

This is a good start for the technology. But it's confusing as hell trying to get it to work the first time. Like many things, it's easy when you know how. I stumbled across the Arduino IDE, also a good start with little success until I realized that this device doesn't have a flasher, so here's the magic: 1. Download the latest version of the Arduino IDE (google it, no problem, you will find it)2. Install IDE3. Set up the Arduino IDE as follows: Go to File -> Settings and copy the following

WLAN and reasonable computing power on a tiny (cheap) board. The cheapest way to get a WiFi enabled device that I know of. A turning point for amateur IoT in the home. For example, it can provide access to a web server or HomeKit service on the network, allowing you to plug it into a USB power source and control garage doors, environmental sensors, buttons, locks, relays, etc. You can update the OTA firmware. also very cool. I'm using an Arduino, but you can program it in many other ways. The…
