The SKR 1.4 Turbo is a high-frequency 32 bit control board, available at a wallet friendly price point. It offers the same high end hardware components, open source Marlin firmware and feature rich expansion ports, while costing a fraction of similar products on the market.
It's equipped with a blazing fast 32 bit ARM Cortex M3 processor, open driver sockets, and plenty of add-on options for convenience.
The SKR 1.4 Turbo control board uses the latest Marlin 2.0 open source firmware, load your own custom build right from the SD card. No burning a bootloader or flashing firmware over USB, the process is entirely automated.
SKR 1.4 Turbo Hardware
The SKR 1.4 Turbo control board is packed with the latest hardware components, firmware and features, making it one of the most advanced solutions on the market at a budget friendly price point.
32 Bit ARM Cortex Processor
This powerful 32 bit ARM Cortex M3 processor boasts a peak operating frequency of 120Mhz. The LPC1768 processor family also incorporates high speed embedded memories, with 512 kB Flash memory and 64 kB SRAM.
This architecture is vastly superior to older 8 bit chips commonly found on 3D Printers, and even more powerful than many existing 32 bit boards. It's capable of handling thousands of calculations per second without a hitch, which means faster, more reliable 3D printing without missing steps or losing acceleration on curves.
Open Driver Sockets
Choose your own stepper motor drivers from a variety of options, with support for the traditional Allegro A4988 and DRV8825, or the silent Trinamic series such as TMC 2130, TMC 2208, TMC 2209 and many more.
A stepper motor driver can fail over time, and should this occur, open drive sockets make it quick and painless to replace them. No need to solder the pins, they are plug-n-play with your favorite model.
Wi-Fi and Writer Module (Optional)
The optional Wi-Fi and BTT Writer Modules enable remote wireless access to manage and control a 3D Printer. Send commands, upload files or monitor prints from the convenience a web interface.
Using the companion Writer module, it's also possible to flash firmware over the network, debug serial ports and more.
DC-DC Power Module (Optional)
The DCDC Mode V1.0 Power Module expansion supplies power to external devices, such as TFT Panels, BLTouch Auto Bed Leveling sensors and Neopixel LEDs.
