Review on 📡 MakerFocus ESP8266 OLED WiFi Development Board - 0.91 Inch ESP8266 OLED Display with CP2102 Chip, Arduino IDE Support, ESP8266 NodeMCU LUA Compatible by Damon Mertz

Excellent Package for Embedded ESP8266 and OLED Display. It is easy to work with and renders text very well. I've attached a video of my project I used NodeMCU for. . This is a drip irrigation timer that I use and using the OLED display as a point of use reference is very helpful. I just had to add the code for the display screens to the source code to make it work. I will order more. I used Arduino with the following settings: Board - NodeMCU 1.0CPU Frequency - 160Upload Speed - 921600ESP8266 library and ThingPulse esp8266-oled-ssd1306 library. Also tested with U8G2 library. I2C communication uses 4 for data, 5 for clock, and 16 for reset. Please note that using the ThingPulse library requires a manual reset of the display. I think this is where the other reviewers struggled. The sketch below shows "Hello World" on your display when the named libraries are installed. #include "SSD1306Wire.h"SSD1306Wire display(0x3c, 4, 5, GEOMETRY_128_32); void setup() { // Manually reset the OLED display pinMode(16, OUTPUT); digital recording (16, LOW); delay(50); digital input (16, HIGH); display.init(); display.flipScreenVertical(); display.setFont(ArialMT_Plain_16); } void loop() { display.setTextAlignment(TEXT_ALIGN_CENTER); display.drawString(64, 8, "Hello World"); display.display();}
