Axis GCP Hat Rev1: common questions

What microcontroller does the Axis GCP Hat Rev1 use?

The Axis GCP Hat Rev1 is built around the Pico, from the RP2040/RP2350 family.

How big is the Axis GCP Hat Rev1?

The Axis GCP Hat Rev1 measures 90 × 60 mm, has 4 copper layers and is 1.572 mm thick.

How many components are on the Axis GCP Hat Rev1?

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

Where can I download the Axis GCP Hat Rev1 design files?

From the Meigs2/Axis repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Axis GCP Hat Rev1 design in my own project?

The repository has no license, so all rights stay with Meigs2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Axis GCP Hat Rev1 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.
