The 1.28-inch circular TFT display module has a built-in GC9A01 driver chip and uses an SPI interface communication, its resolution reaches 240x240, 65K color display color makes the screen clear show color picture.Screen type:IPSWorking voltage:3.3/5VCommunication interface:4-wire SPIResolution:240x240Pixel size:0.135x0.135mmDisplay area: 32.4mmDriver chip:GC9A01Working current:20ma (typical)Interface model:PH2.0-8P/FPCO.5-8PEquipped with a PH2.0 to female cablePositioning :M3 screws (fixed to the copper pillar)Module weight:24gNotice:1. The module is compatible with 3.3V and 5V power supplies, and has a level conversion chip on the board. However, it needs to be clear that the user communication level and the power supply voltage need to be consistent. After testing, the for 5V level communication will not work if the 3.3V power supply is used. ESP32 3.3V level communication was tested using 5V and 3.3V power supply, and there were no abnormalities.2. The screws used to fix the copper pillars are M3 screws. It should be noted that because the copper pillars are through holes and underneath is the metal shell at the bottom of the screen, the part screwed into the copper pillars by the user must not exceed 6mm, otherwise the screen will warp or the edges are cracked.Colour:BlackMaterial:PCB+LCD screenSize:39x36mmPackage Contents:1 * TFT LCD Display Module1 * cbaleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
