DALI STM32: common questions
What microcontroller does the DALI STM32 use?
The DALI STM32 is built around the STM32F031K6Tx, from the STM32 family.
How big is the DALI STM32 PCB?
The DALI STM32 measures 36.8 × 36.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DALI STM32?
22 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the DALI STM32 design files?
From the lactobacil/DALI_STM32 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DALI STM32 design in my own project?
Yes, under the terms of its Apache-2.0 license, which lactobacil chose for the repository.
Can I test firmware for the DALI STM32 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.
