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:IPS Working voltage:3.3/5V Communication interface:4-wire SPI Resolution:240x240 Pixel size:0.135x0.135mm Display area:Φ 32.4mm Driver chip:GC9A01 Working current:20ma (typical) Interface model:PH2.0-8P/FPCO.5-8P Equipped with a PH2.0 to DuPont female cable Positioning method:M3 screws (fixed to the copper pillar) Module weight:24g Notice: 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 arduino 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.
