Raspberry Pi Build HAT Power Supply

This 48 W unit powers the Raspberry Pi Build HAT, the Raspberry Pi computer (except Raspberry Pi 400) and connected LEGO Technic devices from a single source. No extra power supply is needed for the attached hardware. It is designed for makers and educators building motorised LEGO projects with the Build HAT ecosystem.

Check input voltage and connector fit

The supply accepts AC 110~240 V at 50/60 Hz and delivers 8 V at 6 A through a DC2.1 plug with a 5.5 mm outer diameter and 2.1 mm inner diameter. Verify that your Build HAT or Pi board uses this exact barrel size before ordering. The package includes a US-style mains plug, so confirm it matches your local socket or have a suitable adapter ready.

Steady 8 V output under continuous motor load

The unit maintains its rated 8 V 6 A output while driving LEGO Technic motors and sensors over extended periods. This avoids the voltage sag that can occur with undersized adapters when multiple actuators run simultaneously. Stable power keeps the Pi and HAT from resetting during long build sessions or classroom demonstrations.

Questions about this item

Does the box include the Raspberry Pi Build HAT itself or only the 48W 8V 6A power supply with DC2.1 connector?

The package contains only the power supply unit. The Raspberry Pi Build HAT and any LEGO Technic devices must be purchased separately.

Should I choose this 8V 6A model for a standard Raspberry Pi 4 or is it only for the Build HAT?

This supply powers the Build HAT and compatible Raspberry Pi computers except the Raspberry Pi 400. For a standard Pi 4 without the HAT, a 5V USB-C supply is the correct choice.

What does the 48W rating mean when the supply is running a Raspberry Pi and LEGO motors?

The 48W output at 8V 6A provides enough headroom to run the Pi, the Build HAT and multiple LEGO Technic motors simultaneously without needing a second power source.
