About the Avocado rotary PCB

Avocado rotary is an open source Nordic nRF PCB design by auryn31, published on GitHub under the MIT license. It is a 2-layer board measuring 126.8 × 94.6 mm, with 53 components from 7 distinct parts.

Its main chip is the xiao-ble-smd-reversible, from the Nordic nRF family. By type, the board carries 19 diodes, 18 switches, 1 IC and 1 transformer.

It belongs with the keyboards, iot & wireless and power & battery designs in this gallery.

From the project

The Avocado keyboard is a 34-key split, columnar, ergonomic keyboard. It is designed to be a comfortable and efficient keyboard for everyday use.

The Avocado keyboard is a 34-key split, columnar, ergonomic keyboard. It is designed to be a comfortable and efficient keyboard for everyday use.

- Split, Columnar Layout: The split design allows you to position the two halves of the keyboard to match your shoulder width, promoting a more natural and comfortable typing posture. The columnar layout aligns the keys with the natural movement of your fingers. - 34-Key Layout: The 34-key layout is a compact layout that is designed to be efficient and easy to learn. It uses layers to provide access to all of the keys that you need. - Hotswap…

Avocado rotary: common questions

What microcontroller does the Avocado rotary use?

The Avocado rotary is built around the xiao-ble-smd-reversible, from the Nordic nRF family.

How big is the Avocado rotary PCB?

The Avocado rotary measures 126.8 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avocado rotary?

53 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avocado rotary design files?

From the auryn31/avocado_rotary repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Avocado rotary design in my own project?

Yes, under the terms of its MIT license, which auryn31 chose for the repository.

Can I test firmware for the Avocado rotary without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
