Review on DSD TECH 2 PCS IIC OLED Display 0.91 Inch: Perfect Arduino ARM Accessory by James Holker

Revainrating 4 out of 5

Good display, difficult to install

I bought this to use with the Particle Photon controller. The recommended libraries don't work for Photon, but I was able to use the Adafruit libraries and they worked great. The only issue I have is with the physical setup. Only the pins on one side of the board make it a large console and don't fit well in the case. I really need to print some kind of flange mount, but that's difficult because there's very little space between the top pixels of the display and the edge of the display. The attached cutting sheet also does not contain sufficient mechanical drawings. I want these companies to think about how to install this in the project box. The electronics are good, but the mechanics are difficult to understand. Here's sample code in case someone needs a quick start: #include <Adafruit_GFX_RK.h>#include <Adafruit_SSD1306_RK.h>Adafruit_SSD1306 );void setup(){ // SSD1306_SWITCHCAPVCC = Generate 3.3V display voltage in the display .begin( SSD1306_SWITCHCAPVCC , 0x3C); // Address 0x3C for 128x32 // Display framebuffer on display hardware. // Since the buffer is initialized internally by the Adafruit // splash, this is where the splash is shown. display.display(); delay(1000); display.clearDisplay(); display.display(); text size = 3; display.setTextSize(3); display.setTextColor(WHITE); display.setCursor(0,7); display.print("Working"); display.setCursor(0,0); display.display(); // actually render all of the above }

Pros
  • Great construction
Cons
  • Crumpled packaging
