As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example: ABS plastic contains styrene PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP) electrolytic capacitors can contain Ethylene glycol Brass can contain Lead flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA) Aluminum alloys can contain Chromium To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching! |

Beautiful Color Graphics | |
| This board plugs right into the Arduino without the need for wires. It great for plotting geometric shapes. Here is a sketch that draws sine waves. -- // #include SPI.h #include TFT_22_ILI9225.h #include math.h #define TFT_RST A4 #define TFT_RS A3 #define TFT_CS A5 // SS #define TFT_SDI A2 // MOSI #define TFT_CLK A1 // SCK #define TFT_LED 0 // 0 if wired to +5V directly #define TFT_BRIGHTNESS 200 // Initial brightness of TFT backlight optional #define ILI9225_LCD_WIDTH 176 #define ILI9225_LCD_HEIGHT 220 TFT_22_ILI9225 tft = TFT_22_ILI9225TFT_RST, TFT_RS, TFT_CS, TFT_SDI, TFT_CLK, TFT_LED; void setup { tft.begin; tft.clear; } void loop { pixel_loopx0x07FF; // cyan pixel_loopy0x07E0; // green pixel_loopx0x0000; // black pixel_loopy0x0000; // black } void pixel_loopxlong s { for int y = 0; y <= ILI9225_LCD_HEIGHT; y = y + 1 { int x = siny * 5 * DEG_TO_RAD * ILI9225_LCD_WIDTH / 2 + ILI9225_LCD_WIDTH / 2; tft.drawPixelx, y, s; delayrandom2, 50; } } void pixel_loopylong s { for int x = 0; x <= ILI9225_LCD_WIDTH; x = x + 1 { int y = sinx * 5 * DEG_TO_RAD * ILI9225_LCD_HEIGHT / 2 + ILI9225_LCD_HEIGHT / 2; tft.drawPixelx, y, s; delayrandom2, 50; } } | ||

Nice, Compact and easy to use | |
| I picked this display over its larger cousin sold by MPJA because I have to fit it in a tight space. The exact dimensions of the display -not the board- is 2 X 1.5. The display sticks up from the board about 1/8 and could fit through a panel cut out. After running for some time, it is possible to feel a slight warmth, but less than body temperature. Once I hooked up the 6 control lines and two power lines to the arduino nano, everything just worked. I ran all three sample programs with no problem. You cannot just plug it in to the nano and expect it to work like the Mega2560. You can plug it into the Mega, but youll need to change the interface pins in the software to make it use the analog pins instead of the digital ones. For the Nano, connect CLK to D13, SDA to D11, RS to D9, RST to D8, and CS to D10. The display only uses the SPI MOSI pin and the MISO pin -D12- is not used. The fonts included are bitmapped, but if you use the Mega, you can use the TrueType font clones. The Nano doesnt have enough FLASH memory for those. Lastly, the Sine wave program in the photo is not included in the sample programs. Would be nice if MPJA provided that one. | ||
