5-inch LCD display

Control of 3D printers

Bigtreetech (China) launched the Raspberry Pad 5 LCD screen designed for use with FDM (fused deposition modeling) 3D printers. The display’s USB type-C port can serve as a CAN interface.

The device measures 121 mm x 75,9 mm with the touch-screen size of 108 mm x 64,8 mm, which is larger than the default touchscreens of most 3D printing systems on the market, said the manufacturer. It features a resolution of 800 pixels x 480 pixels and comes with the 3D-screen-printing technology by IPS. The display is also suitable for other applications such as smart mirrors, digital photo frames, wall calendars, robotics, and mini computers.

Two buttons on the side allow for adjusting the display brightness, and to flip the screen. The connectivity options include USB type-C, which serves several functions. Beside interfacing to CAN, it can act as a 5-V power supply and can be used to flash the eMMC. Additionally, a HDMI, a 40-pin GPIO (general purpose input/output), Ethernet, three USB 2.0 slots, and a CSI port are available. The HDMI port allows users to connect to an external display of up to 2K resolution. The onboard real-time clock is powered by a separate battery, safeguarding timekeeping in the case of a power outage. To protect connected devices from electrostatic hazards, the display offers ESD (electrostatic discharge) protection. When integrated with an FDM 3D printer, the display will need to be combined with a Raspberry Pi CM4 board and allows users to run the company’s Klipper firmware.

Eric Zhang, Founder of Bigtreetech, said, “The Raspberry Pad 5 is an affordable mainboard solution for your 3D printer and other devices. Compatible with all series of the Raspberry Pi CM4 board, the device makes for a perfect main control board system. As well as 3D printing applications, it’s also intended for makers to use in a variety of DIY (do-it-yourself) projects.” Founded in 2015, the company provides 3D printer electronics and specializes in development of control boards, display screens, and driver boards. The manufacturer’s products were shipped to over 100 countries across the world. Under its Biqu brand, the firm develops its own consumer-grade desktop FFF (fused filament fabrication) 3D printers. The brand also provides 3D printing peripherals and add-ons such as extruders, hotends, heat sinks, linear guides, fans, PTFE (polytetrafluoroethylene) tubing, timing belts, and filaments.
