Fibonacci64
About the Fibonacci64 PCB
Fibonacci64 is an open source STM32 PCB design by aykevl, published on GitHub. It is a 2-layer board measuring 40 × 40 mm, with 82 components from 9 distinct parts.
Its main chip is the STM32L051K8Ux, from the STM32 family. By type, the board carries 64 diodes, 12 resistors, 1 IC, 1 transistor, 1 connector and 1 battery holder.

Collection of microcontroller projects
This is my personal stash of small electronics projects, usually written using TinyGo.
I won't guarantee anything about it. All I can say is that it did work for me at some point and I like sharing what I made. Many things are written once and then mostly forgotten so I probably won't provide any support for any of the code.
Feel free to use this code however you wish (in other words, you can treat it as public domain). Especially for small parts I won't mind if you just copy it in your project. For larger pieces of code or if you copy a project entirely, I would appreciate attribution…

Fibonacci64: common questions
What microcontroller does the Fibonacci64 use?
The Fibonacci64 is built around the STM32L051K8Ux, from the STM32 family.
How big is the Fibonacci64 PCB?
The Fibonacci64 measures 40 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Fibonacci64?
82 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Fibonacci64 design files?
From the aykevl/things repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Fibonacci64 design in my own project?
The repository has no license, so all rights stay with aykevl. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Fibonacci64 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
