The KiCad project lives in the promesoft/KicadJE_uP_DAC repository on GitHub; these links point at the commit this page was built from.

KicadJE uP DAC: common questions

What microcontroller does the KicadJE uP DAC use?

The KicadJE uP DAC is built around the STM32F103C8Tx, from the STM32 family.

How big is the KicadJE uP DAC PCB?

The KicadJE uP DAC measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KicadJE uP DAC?

269 components, from 86 distinct parts. The full bill of materials is listed on this page.

Where can I download the KicadJE uP DAC design files?

From the promesoft/KicadJE_uP_DAC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the KicadJE uP DAC design in my own project?

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

Can I test firmware for the KicadJE uP DAC 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.
