Klyr f072: common questions
What microcontroller does the Klyr f072 use?
The Klyr f072 is built around the STM32F072CBTx, from the STM32 family.
How big is the Klyr f072 PCB?
The Klyr f072 measures 65 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Klyr f072?
31 components, from 16 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Klyr f072 design files?
From the dialgorithm/klyr-f072 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Klyr f072 design in my own project?
The repository has no license, so all rights stay with dialgorithm. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Klyr f072 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.
