The KiCad project lives in the AllenNeuralDynamics/harp.device.pico-template repository on GitHub; these links point at the commit this page was built from.

Usb powered small: common questions

What microcontroller does the Usb powered small use?

The Usb powered small is built around the RP2040, from the RP2040/RP2350 family.

How big is the Usb powered small PCB?

The Usb powered small measures 36 × 28 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Usb powered small?

40 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb powered small design files?

From the AllenNeuralDynamics/harp.device.pico-template repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Usb powered small design in my own project?

The repository has no license, so all rights stay with AllenNeuralDynamics. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Usb powered small 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.
