Coconut: common questions

What microcontroller does the Coconut use?

The Coconut is built around the Sparkfun_Pro_Micro, from the AVR/Arduino family.

How big is the Coconut PCB?

The Coconut measures 212.6 × 79.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Coconut?

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

Where can I download the Coconut design files?

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

Can I use the Coconut design in my own project?

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

Can I test firmware for the Coconut without the hardware?

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