BIGTREETECH SKR V1.4 Turbo Control Board with ESP-01S WiFi Module for 3D Printers

Upgrade your workshop with a compact, feature-rich controller built for precise 3D printing. This board is designed to sit quietly behind your printer frame while handling complex motion and connectivity so you can focus on prints rather than tuning. It suits hobbyists and makers who need reliable stepper control and wireless access to print files.

BIGTREETECH SKR V1.4 Turbo Control Board - Designed for 3D printer control and connectivity

The SKR V1.4 Turbo centres around an ARM Cortex-M3 CPU to deliver responsive control across a wide range of machines. Its small footprint (110 × 85 mm) and mounting size (102 × 76 mm) make it straightforward to fit into many enclosures. Built-in support for an ESP-01S WiFi module gives optional wireless convenience for sending G-code and monitoring jobs.

Everyday impact: Expect stable motor performance and flexible integration with popular printer topologies thanks to multiple driver interfaces and broad architecture support.

Why it fits your routine

• Flexible power: Accepts DC 12V–24V with current range suitable for common printer setups.
• Responsive logic: 3.3V logic voltage paired with an ARM Cortex-M3 CPU for consistent control.
• Drive compatibility: Supports SPI, UART and STEP/DIR drive modes to work with a variety of stepper drivers.
• Extensible motor interfaces: X, Y, Z, E0, E1 reextendable interfaces with up to 256 microstepping for finer motion.
• File and architecture support: Reads G-code and is compatible with XYZ, delta, Kossel, Ultimaker and CoreXY machines.

Physical and technical details include an appearance size of 110 × 85 mm, mounting size 102 × 76 mm, and support for ESP-01S WiFi connectivity to add wireless control where needed.
