Features: The RP2404 1.28-inch round LCD screen module is a high-performance microcontroller development board. Built-in GC9A01 driver chip, SPI interface communication. 240x240 resolution, 65K color, can clearly display color images. Uses SPI control, won't occupy too many interface pin resources, and can access main control boards for RaspberryPi/Arduino/STM32. Provides a complete supporting information manual (for RaspberryPi /for Arduino / STM32 and other example programs). Package includes: 1x 1.28-inch LCD module 1x PH2.0 8-pin connecting cable Specifications: Diameter: Approx. 4cm/1.57 inches Cable length: Approx. 20cm/7.87\" Product name: 1.28\" 240x240 LCD screen Resolution: 240x240 Control chip: GC9A01 Interface: 4-wire SPI Screen size: 32.4mm Screen: IPS Pixel size: 0.135x0.135mm Working voltage: 3.3V/5V Other Parameters: Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz 264KB static RAM and 2MB built-in flash memory USBC connector, keeps it updated, easier to use All GPIOs (total of 30, but some pins have been connected to the internal bu circuit, so pay attention when multiplexing. See the details) USB1.1 with device and host support Low-power sleep and dormant modes Drag-and-drop programming with mass storage via USB port 2xSPI, 2x I2C, 2x UART, 4x 12-bit ADC, 16x controllable PWM channels Accurate clock and timer on chip Temperature sensor Accelerated floating-point libraries on chip 8x Programmable I/O state machines for custom peripheral support Built-in lithium battery charging and discharging interface is beneficial for RP2040-LCD-1.28 to be used in some mobile scenes. Note: Please allow 0-1cm error due to manual measurement. Make sure you don't mind before ordering. Due to the difference between different monitors, the picture may not reflect the actual color of the item.
