It is fully compatible with for Nodemcu V3, but cheaper than it is. for NodeMcu is an open source firmware and development tool that helps you prototype your IOT products in several script lines.
The ESP8285-based development kit integrates GPIO, PWM, IIC, 1-Wire and ADC into a single board.
The fastest way with the for NodeMCU firmware, for your development to provide support!
Including USB-TTL, plug and play
10 GPIOs, each GPIO can be PWM, I2C, 1 line
FCC certification WI-FI module (coming soon)
Advanced APIs for hardware IO can significantly reduce redundant tasks for configuring and manipulating hardware;
The code is interactive in the script;
Nodejs style network API;
The event-driven API for web applications helps developers write code that runs on a 5mm * 5mm size MCU in Nodejs style;
Greatly speed up your IOT application development process;
Minimum cost WI-FI;
