Pico H-bridge complete: common questions

What microcontroller does the Pico H-bridge complete use?

The Pico H-bridge complete is built around the Pico, from the RP2040/RP2350 family.

How big is the Pico H-bridge complete PCB?

The Pico H-bridge complete measures 84.1 × 66 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pico H-bridge complete?

77 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pico H-bridge complete design files?

From the rosstimo/MotorProject repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Pico H-bridge complete design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Pico H-bridge complete without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
