MicroPython with ESP32 and ESP8266: Interacting with GPIOs

Micropython HC-SR04 - ESP8266. Elsewhere on the internet they suggested that you put a resistor inbetween the echo and the pin on the NodeMCU board (ESP8266), This made the measurements trip out pretty badly. So right now I have it working 100% with 5v and Ground (to the HC-SR04) connected to my RPi GPIO, and the trigger and echo connected

The ESP8266 is a 3. 3V microcontroller, so its I/O operates at 3. 3V as well. The pins are not 5V tolerant, By default, the IC library uses pin 4 as SDA and pin 5 as SCL. (The data sheet specifies GPIO2 as SDA and GPIO14 as SCL. ) The maximum speed is approximately 450kHz. SPI.

/27/2017All ESP8266 boards running MicroPython. Official boards are the Adafruit Huzzah and Feather boards. as the scripts would use the default pin numbering internally, and thus would work perfectly fine on all ESP8266 boards. I'd pass ESP8266 pin names to the constructor and have the hardware mappings in the docs. After all, you only need to

ESP8266: NodeMCU Pin mappings – techtutorialsx

ESP8266 Thing Hookup Guide If you've used Arduino in the past, there will be some new programming schemes to get used to in ESP8266 land. Pin Mappings. As with any other Arduino, the pin mappings printed on the board match the pin you read or write to. The SDA and SCL pins can be referenced as 2 and 14 respectively.
