Features: RP2404 1.28-inch round LCD display module is a high-performance microcontroller development board. Built-in GC9A01 driver chip, SPI interface communication. 240x240 resolution, 65K color, can clearly display color pictures. Use SPI control, will not occupy too much interface pin resources, it can access to main control boards for RaspberryPi/Arduino/STM32. Provide a complete supporting information manual (for RaspberryPi /for Arduino / STM32 and other sample programs). Specifications: Diameter: Approx. 4cm/1.57 inch Cable Length: Approx. 20cm/7.87" Product Name: 1.28" 240x240 LCD Display Screen Resolution: 240x240 Control Chip: GC9A01 Interface: 4-wire SPI Display Size: 32.4mm Display Panel: IPS Pixel Pitch: 0.135x0.135mm Working Voltage: 3.3V/5V Other Parameters: Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz 264KB of Static Random-Access Memory, and 2MB of on-board flash memory USBC connector, keeps it up to date, easier to use All GPIOs (30 in total, but some pins have been connected to the internal bu-circuit, so please pay attention when multiplexing. Please refer to the detail) are led out by 1.27-pitch bus bar. USB1.1 with device and host support Low-power sleep and dormant modes Drag-and-drop programming using mass storage over 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 states machines for custom peripheral support On-board 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. pls make sure you do not mind before you order. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Package includes: 1x 1.28-inch LCD Module 1x PH2.0 8pin Connection Cable
