About the Pico hub75 PCB

Pico hub75 is an open source RP2040/RP2350 PCB design by execuc, published on GitHub under the Custom license license. It is a 2-layer board measuring 87.6 × 59.7 mm, with 27 components from 15 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 10 connectors, 4 capacitors, 3 switches, 3 resistors, 2 jumpers and 2 diodes.

It belongs with the usb & debug tools designs in this gallery.

From the project

USB to interfaces implementing MicroPython "machine" module functionalities on a computer.

There are some kicad projects of a PCB with some I/O but mostly headers. Caution: I am not an electronic engineer, check schematics and PCB before using it !

Zipped gerber file is available: Gerber file

There are two jumpers to wire D and E signal in case of 1/16 and 1/32 panels.

Pico hub75: common questions

What microcontroller does the Pico hub75 use?

The Pico hub75 is built around the Pico, from the RP2040/RP2350 family.

How big is the Pico hub75 PCB?

The Pico hub75 measures 87.6 × 59.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pico hub75?

27 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico hub75 design files?

From the execuc/u2if repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pico hub75 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Pico hub75 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.
