The RP2040-0.42LCD is a high-performance development board, integrating a 0.42-inch LCD (70x40 resolution) with flexible digital interfaces. It features the RP2040 microcontroller chip. The RP2040 has a dual-core Arm Cortex-M0+ processor clocked at 133MHz with 264KB of internal SRAM and 2MB of internal flash memory. Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. This means that when you want to program new firmware, you can hold down the BOOTSEL button while connecting it to USB (or pull the RUN/Reset pin to ground), and it will appear as a USB disk to which you can drag firmware. There is good C/C++ support, unofficial (but very good) support for Python. You can also use MicroPython and CircuitPython. Features: RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3V logic and 264 KB RAM 2 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code. No EEPROM Four 12-bit ADCs (one more than Pico) Two I2C, Two SPI, and Two UART peripherals Integrated 0.42-inch LCD Both Reset button and Bootloader select button for quick restarts (no unplug-replug to restart code) 1x RGB (GPIO2) 3.3V indicator LED 3.3V regulator with 500mA current output USB Type C connector allows access to built-in ROM USB bootloader and serial debugging Size: 23.5 x 18 mm Material: PCB Color: Purple Package Contents: 1 x RP2040 Development Board Only the above package content is included, other products are not. Note: Light reflection and different displays may cause the color of the item in the picture to be slightly different from the real thing. The allowed measurement error is +/- 1-3 cm.
