Connect NodeMCU devkit 0.9 to Arduino Mega
Posted: Tue Jun 16, 2015 3:16 am
Hi,
I have a NodeMCU board (yellow, v0.9, 05/12/2014 release) and an Arduino Mega.
Can someone help please, how to connect the NodeMCU to the Arduino. I searched for hours by google, but didn't find the correct pin description about connect the board to Arduino.
The NodeMCU board is in AP mode. In "standalone" mode (connect only with USB to the PC) works fine. The IP adress has a respond in browser. ("Hello from ESP8266" ) In this case I used NodeMCU lua firmware with init.lua, but I got the same result with simply Arduino webserver code. (Standalone works in both case)
I had tried
devkit lower rigth corner 3.3V - Breadboard power supply 3.3V
devkit lower rigth corner GND - Breadboard power supply GND (Common with Arduino GND)
devkit RX - Arduino TX
devkit TX - Arduino RX
I didn't found the CH_PD pin on devkit, maybe the "EN" pin same as the CH_PD in other modules? What should I do to work together these devices?
I would like to measure and show the sensor values connected on Arduino Mega, (maybe on Thingspeak) and control the Mega GPIO pins.
Sorry for my bad english, I hope you will understand
