ITEM NAME:WeMos D1 UNO R3 CH340 WIFI ESP8266 ESP-12E Develop Board for Arduino IAF Descriptio n Material: PCB Color: Blue Size: 50*30*20mm Weight: 40G Product features: 1. The standard pin interface spacing is fully compatible with Arduino Uno, Mega, etc. (except arduino of standard size, such as Nano and Mini) 2: the advanced 3.3v power supply chip (the same as the power supply chip of the official CC3000 extension board) is adopted to make the 3.3v provided in the Arduino board more accurate and make the ESP8266 work as well as the official CC3000 chip without any difference. 3. Introduce a WiFi module power supply/maintenance interface for developers to extend power supply and maintenance. 4. Industrial-level stable serial port WiFi module esp8266-12 is mounted on the board. Enhanced PCB antenna is used for better signal. 5. The operation mode of esp8266-12 industrial-level stable WiFi module (such as operation mode and upgrade mode) can be quickly switched through the dial code switch, integrated serial port chip, and wrote firmware quickly. 6: the built-in 5V to 3.3v TTL level converter prevents the high-voltage Arduino TTL level from harming the WiFi module. (general modules are not available.) 7. Industrial-level stable WiFi module of esp8266-12 has metal shielding cover and strong anti-interference performance. 8: with standard spacing, all interfaces of esp8266-12 industrial-level stable WiFi module are introduced for further development of developers. 9: provide the Arduino library of esp8266-12 industrial-level stable WiFi module compiled by this website, which can be controlled by very simple instructions and provide routines. 10:7x24 online QQ group, BBS, email technical guidance, sample program, technical data sharing. :11: with the superposition design, you can continue to add other modules on it for convenient use. :12: four leds on board display the status of ESP8266, which are PWR,DFU,AP and STA respectively.
