About the UnOrthoDox 17 PCB

UnOrthoDox 17 is an open source RP2040/RP2350 PCB design by TweetyDaBird, published on GitHub. It is a 2-layer board measuring 76.2 × 96.7 mm, with 67 components from 8 distinct parts.

Its main chip is the RP2040-Zero, from the RP2040/RP2350 family. Other key parts include the SN74LV1T34DBV. By type, the board carries 19 switches, 18 diodes, 4 capacitors and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

A 'simple' 17-20 key Numpad

The name comes from the slightly unortodox placement of the controller straddling the hot-swap socket, with not all pins soldered, and the fact that it can be built as a 20-key ortholinear macro pad.

- Full Sandwich Case design - Low cost/Simple to build - Powerful and Flexible MCU - Compatible with QMK/Vial and ZMK firmware - Reversible for SouthPaw's - Dual Rotary Encoders - Per-Key RGB - Build instructions are printed on the backplate for an easy build.

UnOrthoDox 17: common questions

What microcontroller does the UnOrthoDox 17 use?

The UnOrthoDox 17 is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the UnOrthoDox 17 PCB?

The UnOrthoDox 17 measures 76.2 × 96.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UnOrthoDox 17?

67 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the UnOrthoDox 17 design files?

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

Can I use the UnOrthoDox 17 design in my own project?

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

Can I test firmware for the UnOrthoDox 17 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.
