About the MacRo Pad PCB

MacRo Pad is an open source RP2040/RP2350 PCB design by dutzzzzu, published on GitHub. It is a 2-layer board measuring 90 × 66 mm, with 16 components from 5 distinct parts.

Its main chip is the MOUDLE-SEEEDUINO-XIAO, from the RP2040/RP2350 family. By type, the board carries 8 switches, 6 diodes, 1 IC and 1 connector.

It belongs with the keyboards and displays & leds designs in this gallery.

MacRo Pad: common questions

What microcontroller does the MacRo Pad use?

The MacRo Pad is built around the MOUDLE-SEEEDUINO-XIAO, from the RP2040/RP2350 family.

How big is the MacRo Pad PCB?

The MacRo Pad measures 90 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MacRo Pad?

16 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the MacRo Pad design files?

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

Can I use the MacRo Pad design in my own project?

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

Can I test firmware for the MacRo Pad 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.
