About the Spor-Bicycle PCB

Spor-Bicycle is an open source STM32 PCB design by BurakOnemli, published on GitHub. It is a 2-layer board measuring 95 × 48.8 mm, with 28 components from 15 distinct parts.

Its main chip is the STM32L011K4T6, from the STM32 family. Other key parts include the LD3985M33R_SOT23. By type, the board carries 10 capacitors, 8 resistors, 5 connectors, 2 ICs, 2 diodes and 1 battery holder.

From the project

My neighbour had a sport bicycle which's paint is falling off and the screen was not working properly so I dedided to renovate it.

Spor-Bicycle: common questions

What microcontroller does the Spor-Bicycle use?

The Spor-Bicycle is built around the STM32L011K4T6, from the STM32 family.

How big is the Spor-Bicycle PCB?

The Spor-Bicycle measures 95 × 48.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spor-Bicycle?

28 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spor-Bicycle design files?

From the BurakOnemli/Spor-Bicycle repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Spor-Bicycle design in my own project?

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

Can I test firmware for the Spor-Bicycle 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.
