Kedtracker: common questions
What microcontroller does the Kedtracker use?
The Kedtracker is built around the STM32F103, from the STM32 family.
How big is the Kedtracker PCB?
The Kedtracker measures 82.7 × 56.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Kedtracker?
78 components, from 41 distinct parts. The full bill of materials is listed on this page.
Where can I download the Kedtracker design files?
From the kedder/kedtracker repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Kedtracker design in my own project?
The repository has no license, so all rights stay with kedder. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kedtracker 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.
