BIGTREETECH TFT70 V3.0 Display Touch Screen Two Working Modes for SKR Octopus Control Board
$68.00
The BIGTREETECH TFT70 V3.0 is a versatile 7″ touch screen designed for SKR and Octopus control boards. It offers two working modes: a full-featured capacitive touchscreen interface and a fallback LCD12864 emulation for broad firmware compatibility. Navigation includes a rotary encoder for mode switching and brightness control. With UART support for SD- and USB-based file printing, WiFi module and filament detection ports included, it replaces the traditional LCD12864 while offering modern touch interaction. Plug it in, flash via SD card, and switch modes with one long-press—simple, powerful, and flexible.
Key Features:
Dual Operation Modes: Choose between a touchscreen GUI mode (UART serial) and legacy LCD12864 emulation for compatibility with Marlin-based firmware.
Quick Mode Switching: Hold the encoder for ~3 seconds to toggle modes, with no firmware reinstall required.
Integrated SD Card Slot: Supports firmware updates and file access via SD or USB in touchscreen mode—plug-and-play convenience.
Expanded I/O Ports: WiFi module, filament runout detection, and PS‑ON auto-shutdown ports on board for advanced integrations.
