The 1.28-inch circular touch TFT display module is equipped with a built-in GC9A01 driver chip, which uses SPI interface communication. Its resolution reaches 240x240, and the 65K color display color allows the screen to display color images clearly. The touch function can be driven using the CST816D dedicated capacitive touch chip and IIC. Screen type: IPS Working voltage: 3.3/5V Communication interface: 4-wire SPI Resolution: 240x240 Display area: 32.4mm in the middle Driver chip: GC9A01 Working current: 20ma (typical) Interface model: mx1 25-8P + mx1. 25-4P； Equipped with an mx1.25-8P and mx1.25-4P to DuPont female wire Positioning method: M2 screw (fixed to copper pillar) Module weight: 17.2g Module size: 42.1 * 43 * 11 5mm GND: Negative power supply, ground VIN: Positive power supply, 3.3-5V, needs to be consistent with the communication level SCL: SPI clock signal input port SDA: SPI data input port RES: Reset, low level enable DC: Data/Command Selection, Low Level Command, High Level Data CS: Chip selection, low-level enable BLK: Backlight, suspended to ground off, default pull-up to 3 3V TP_SCL: Touch Function IIC Communication Clock Port TP_SDA: Touch Function IIC Communication Data Port TP-RST: Touch reset pin, low level valid TP-INT: Touch interrupt pin, output high level matters needing attention The module is compatible with 3.3V and 5V power supply, and is equipped with a level conversion chip on the board. However, it should be clarified that the user communication level and power supply voltage need to be consistent. After testing, it was found that using 3.3V power supply for Arduino 5V level communication will not work, while ESP323.3V level communication using 5V and 3.3V power supply tests showed no abnormalities. The height of the M2 copper pillar is 4.5mm, so the screw you are using cannot exceed this height.

• User-friendly 3.3/5V operation voltage for broad compatibility. Convenient 8P + 4P interface with MX1.25 connectors included. Enhance your Arduino LCD projects with this TFT display module
• Enjoy seamless touch control with the IIC-driven capacitive touch feature. Compact module size of 42.1 x 43 x 11.5mm fits well in various applications. Upgrade your Arduino screen projects with this LCD display module
