PowerBRRR 48V Injection Daughter Board for Stepkick Drivers by tehmaze
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
