Overview

• RP2040-0.42 LCD is a high-performance development board that integrates a 0.42-inch LCD display (70 × 40 resolution). Flexible digital interface. It integrates Raspberry Pi's RP2040 microcontroller chip. The RP2040 uses a dual core Arm Cortex-MO+processor with a main frequency of 133 MHz and built-in 264KB and 2MB flash memory. There is a "permanent ROM" USB UF2 boot program inside RP2040. This means that when you want to program new firmware, you can press and hold the B00TSEL button while plugging it into USB (or pulling the RUN/Reset pin to the ground). It will appear as a USB disk drive, and you can drag the firmware onto it. There is good C/C++support, unofficial (but very good) Arduino support, and you can also use microphon and circuitPython.
