Meow70: common questions

What microcontroller does the Meow70 use?

The Meow70 is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Meow70 PCB?

The Meow70 measures 364.2 × 100.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Meow70?

144 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Meow70 design files?

From the aerogull/meow70 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Meow70 design in my own project?

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

Can I test firmware for the Meow70 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.
