About the RP2040InnerColumn PCB

RP2040InnerColumn is an open source RP2040/RP2350 PCB design by unseensnick, published on GitHub under the MIT license. It is a 2-layer board measuring 16.4 × 36.9 mm, with 35 components from 17 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the ZD25Q128CWIGR, USBLC6-2P6 and AP2112K-3.3TRG1. By type, the board carries 19 capacitors, 6 resistors, 4 ICs, 2 switches, 1 crystal and 1 connector.

It belongs with the keyboards designs in this gallery.

From the project

A KiCad 10 template for a chip-down RP2040 controller that lives on the back of a Choc split keyboard, in the strip beside the inner key column, the way the Keebart Sofle Choc Pro does it. The layout follows the ScottoModules idea: copy the schematic and board into a keyboard pro

A KiCad 10 template for a chip-down RP2040 controller that lives on the back of a Choc split keyboard, in the strip beside the inner key column, the way the Keebart Sofle Choc Pro does it. The layout follows the ScottoModules idea: copy the schematic and board into a keyboard project, then wire the GPIO labels to the matrix.

The circuit is the controller half of the audited velvet74.kicadsch` in the repo root, so reference designators and LCSC part numbers match the keyboard.

RP2040InnerColumn: common questions

What microcontroller does the RP2040InnerColumn use?

The RP2040InnerColumn is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040InnerColumn PCB?

The RP2040InnerColumn measures 16.4 × 36.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2040InnerColumn?

35 components, from 17 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 RP2040InnerColumn design files?

From the unseensnick/Velvet74 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 RP2040InnerColumn design in my own project?

Yes, under the terms of its MIT license, which unseensnick chose for the repository.

Can I test firmware for the RP2040InnerColumn 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.
