About the ElementWing PCB

ElementWing is an open source RP2040/RP2350 PCB design by jamiejcole, published on GitHub. It is a 2-layer board measuring 321.5 × 233.4 mm, with 188 components from 95 distinct parts.

Its main chip is the Raspberry_Pi_Pico, from the RP2040/RP2350 family. Other key parts include the MCP23017_SO. By type, the board carries 90 switches, 90 diodes, 2 ICs and 2 resistors.

From the project

ETC EOS Element Wing custom PCB project

It's a full sized EOS command wing, featuring the standard ETC key layout and 4 customisable rotary encoders.

The PCB consists of a 13x8 diode keyswitch matrix, where each row and column are connected to a GPIO pin on the Pico. The A/B/SW pins of each encoder are connected to a GPIO port on the MCP23017, which is connected to the Pico on the I2C0 interface, with the SDA and SCL lines pulled up to 3v3 with 2.2k resistors.

ElementWing: common questions

What microcontroller does the ElementWing use?

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

How big is the ElementWing PCB?

The ElementWing measures 321.5 × 233.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ElementWing?

188 components, from 95 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 ElementWing design files?

From the jamiejcole/ElementWing 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 ElementWing design in my own project?

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

Can I test firmware for the ElementWing 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.
