Everyone loves NodeMCU, as it is based on ESP8266 WiFi microcontroller and there are thousands of example projects and codes using it. With its huge flash size, 32-bit processor and ready WiFi integration, it's perfect for many electronics, robotic and IoT projects. It also supports many programming language which include: LUA script, micropython, Arduino and etc. Yet, to be frank there are too many versions of NodeMCU and it confused many :(
We carry NodeMCU V3 which has similar layout but comes with wider pin to pin space (side to side), 1100mil (1.1 inch) or 27.94mm to be exact. It cannot be used on breadboard. So we get smaller or narrower version of NodeMCU. This V2 Doit ESP12E NodeMCU comes with smaller layout while maintaining the GPIO sequences on both side. The width between side pin is 900mil or 22.86mm, and this allows a row of holes on breadboard for prototyping when it is stack on it.
You can combine this NodeMCU with L293D shield to build a WiFi controlled mobile robot or remote car:
- A programable WiFi module.
- Operating Voltage:
- 5V via USB or Vin pin
- 3.3V for controller and GPIO
- Flash Memory: 4 MB
- SRAM: 64 KB
- Clock Speed: 80 MHz
- Can be programmed with Arduino IDE.
- USB-TTL converter, CH340 built-in for serial communication, debugging and programming loading.
- 10 GPIOs (D0-D10), PWM functionality, I2C and SPI communication, 1-Wire and ADC, A0 etc. All in one board.
- Integrated support for WiFi network
- Code like Arduino, but interactively in Lua script
- Nodejs style network API
- Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style
- Greatly speed up your IoT application developing process
- Lowest cost WiFi
- Weight: 10g
- Product dimensions: 48mm(L)x25mm(W)x13mm(H)
- 1 x NodeMCU V2 Doit ESP12E (Narrow)
- Schematic & PCB, Source Code, API Documents
- CH34X driver (Please ensure the board is plug in to computer USB port during driver installation)
