LCSC-boards LCKFB-HSPI-D133EBS

LCKFB and Jangxin jointly launch an ultra cost-effective industrial-grade display development board. The MCU runs at 480MHz with a massive memory combination of 1MB SRAM and 8MB PSRAM, plus 16MB of large-capacity Flash storage. Developed with RT-Thread and LVGL-V9, it supports smooth RGB and LVDS screen operation at 720P@60FPS. A nearly 200,000-word beginner's manual pairs with nearly 100 module porting examples for easy entry into RISC-V industrial-grade graphical display. Provides a rich variety of I/O interfaces — including GPIO, SPI, I²C, UART, and PWM — to meet diverse application needs. RGB565 interface with touch and LVDS interface with touch require no expansion; standard 40-PIN screens connect freely. The 24-pin interface is compatible with OV5640/OV2640 cameras and 100M Ethernet expansion boards. Onboard Wi-Fi flexibly adapts to mainstream RTL8189FTV and RTL8733BS modules. Full open-source schematics and PCB, paired with a comprehensive beginner's manual and nearly 100 module examples, enable rapid entry into industrial-grade display MCU development to accelerate project development and deployment.
