PowerBRRR is a 48V power-injection daughter board for StepStick-format stepper drivers. It lets a compatible high-voltage driver take motor power from a separate 48V rail while the controller board still handles the StepStick logic interface.
Why use it
- Adds a cleaner 48V injection point for high-voltage StepStick drivers instead of pushing motor voltage through a controller board that was not designed for that rail.
- Built around the open-source tehmaze PowerBRRR design.
- Best matched with true 48V-capable TMC5160-class drivers, such as Fysetc BIG 5160, and a dedicated 48V supply such as the MEAN WELL IRM-90-48ST.
Specifications
- Function: 48V motor-power injection daughter board for StepStick driver sockets
- Project: PowerBRRR by tehmaze
- Driver format: StepStick-style stepper drivers
- High-voltage target: 48V systems when used with drivers and controller hardware rated for that voltage
- Visible assembly: PCB with StepStick headers, power connector, and electrolytic capacitor
Fitment and setup notes
- Use only with electronics you have verified for 48V operation. The PowerBRRR project specifically calls out that only some HV StepStick drivers are truly 48V-capable.
- Follow the project instructions for VM pin removal / isolation and insulation. The official notes recommend covering the back with Kapton tape.
- For StepStick lighting or visual status mods instead of power injection, see the Stepstick Neopixel Board by timmit99.
What it is not
- Not a stepper driver by itself; it is an injection daughter board used with a separate StepStick driver.
- Not a universal 48V upgrade. Driver voltage rating, controller layout, wiring, insulation, and cooling still matter.
- Not beginner-safe: 48V electronics can damage hardware or injure people if installed incorrectly.
