About the SniqxPad PCB

SniqxPad is an open source RP2040/RP2350 PCB design by arnav-kr, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 81 × 62 mm, with 22 components from 5 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 10 diodes, 9 switches, 1 IC and 1 connector.

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

SniqxPad: common questions

What microcontroller does the SniqxPad use?

The SniqxPad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the SniqxPad PCB?

The SniqxPad measures 81 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SniqxPad?

22 components, from 5 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the SniqxPad design files?

From the arnav-kr/SniqxPad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the SniqxPad design in my own project?

Yes, under the terms of its AGPL-3.0 license, which arnav-kr chose for the repository.

Can I test firmware for the SniqxPad 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.
