BIGTREETECH TFT43 V3.0 &TFT50 V3.0 & TFT70 V3.0 Display Touch Screen Two Working Modes for SKR Octopus Control Board

Upgrade your 3D printer interface with the BigTreeTech TFT43 / TFT50 / TFT70 V3.0 Dual-Mode Touchscreen Display — a versatile color screen available in three sizes (4.3", 5", and 7") that combines modern touchscreen convenience with backward compatibility.

These high-resolution displays feature a powerful ARM Cortex-M3/M4 MCU and offer two working modes in one device: full touchscreen (UART) mode for intuitive color menus or classic 12864 LCD + encoder mode for maximum compatibility with older firmware setups. The large, sharp screen provides clear visibility of temperatures, print progress, and settings.

Key Features:

• Dual Operating Modes — Easy switching between responsive touchscreen UI and traditional 12864 graphic LCD mode
• High-Resolution Color Display — Crisp visuals with bright backlight for excellent readability
• SD Card & USB Support — Firmware updates and G-code file management directly from the screen (in touchscreen mode)
• Expansion Ports — WiFi module support, filament runout sensor (FIL-DET), and PS-ON auto-shutdown
• Multiple Size Options — Choose 4.3" (TFT43), 5" (TFT50), or 7" (TFT70) to match your build space and preference
• Rich Connectivity — Compatible with EXP1/EXP2 for 12864 mode and RS232/UART for touchscreen mode
