The BIGTREETECH SKSM V1.0 is a compact safe shutdown module designed specifically for Klipper 3D printers. It acts as a reliable UPS-style power backup for your Single Board Computer (SBC) such as Raspberry Pi 3/4B, BTT Pi, or CB1, preventing data corruption and system damage during unexpected power outages.

Key Features:

  • Smart Power Outage Detection — High-sensitivity MCU quickly detects power loss and switches to battery backup automatically.
  • Stable 5V Output — Delivers up to 2A via BAT and USB ports to keep your SBC running safely during shutdown.
  • Built-in Battery Backup — Provides several seconds of power (typically 13–15 seconds at 5W) for graceful shutdown and safe file saving.
  • Current Limiting Protection — Protects connected devices from overcurrent.
  • Easy Integration — Works with 12–24V DC printer power supplies; simple wiring for Klipper setups.
  • Compact Design — Small footprint (40.8 × 32.9 mm) for easy mounting inside printer enclosures.

Benefits:

  • Prevents corrupted SD cards or lost print jobs when power fails
  • Allows the Klipper host (Raspberry Pi) to shut down properly
  • Enhances reliability for long prints and unattended operation
  • Essential upgrade for any Klipper-based 3D printer using an SBC
