RP2040-0.42LCD is a high-performance Development board ,Integrated 0.42inch LCD (70x40 resolution).with flexible digital interfaces. It incorporates for 's RP2040 microcontroller chip.The RP2040 features a dual-core Arm Cortex-M0+ processor clocked at 133MHz with 264KB internal SRAM and 2MB internal flash .Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What means is when you want to program new firmware, you can hold the BOOTSEL button while plugging it into USB (or pulling the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto.There is great C/C++ support, unofficial (but really good) for support, You can also for micropthon and for circuitpython.RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3V logic and 264 KB RAM2 MB SPI FLASH chip for storing files and for CircuitPython/for MicroPython code .
