D1 Mini V3 Nodemcu Wifi Esp8266ex Usb Ch340c

D1 Mini V3 Nodemcu WIFI Esp8266ex Usb Ch340c. The NodeMCU MINI V3.0 is a development board that is based on the popular ESP8266EX chip. The concept is very similar to that of the Arduino, a microcontroller connected through a USB-Serial bridge that interacts with software on the PC. The ESP8266 in the WEMOS D1 MINI V3.0 is the latest version quite easy to implement as an integrated circuit for WIFI. It is a SoC (System on Chip) that integrates in a single piece of silicon an applications processor with electronics necessary for RF communication (WIFI). This board allows us to take advantage of the processor that is inside the ESP8266EX and make software that runs on the Arduino ide, not only to use it as a bridge between the microcontroller and the WIFI network The latest version of Wemos D1 mini V3.0 It has an esp8266 EX a CPU with a 26 megahertz crystal an external flash memory of 4 Megabytes 32megabit, button and reset fuse 500 milliamperes LED of operation and mounting holes to fix the project conserves the reset button, external antenna and identical pin outs at the Previous versions on the back of the board, the CH340G has been replaced by the Ch340C, a “slope” jumper was added that goes between reset and D0, so if you do a project with deep sleep, you can make a bridge by soldering with that jumper which is quite useful.

Differences between the previous model 2.2 and the more recent model 3.0

• The 12MHz crystal was replaced by a 26Mhz one
• The Esp8266X was replaced by an ESP8266EX – 500ma reset fuse was added
• The Ch340G was replaced by the CH340C
• A Sleepy link jumper – Board mounting holes added
