P2040-1.14LCD is a high-performance Development board , Integrated 1.14 inch LCD (240x135 resolution, IPS screen, 65K RGB colors). with flexible digital interfaces. It incorporates 's RP2040 microcontroller chip.The RP2040 features a dual-core ArmCortex-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 Arduinosupport, You can also micropthon and circuitpython.Features:Lora module: With SX1278(410-525MHz,+18dBm),If you select the sx127x module version, the SD card read / write function will not be supportedSize: 51.5 x 25 mmRP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3Vlogic and 264 KB RAM2 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code .
