8ZoneTriac: common questions

What microcontroller does the 8ZoneTriac use?

The 8ZoneTriac is built around the STM32F030C8T6, from the STM32 family.

How big is the 8ZoneTriac PCB?

The 8ZoneTriac measures 181.7 × 107.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 8ZoneTriac?

141 components, from 30 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 8ZoneTriac design files?

From the mekatrol/electronics 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 8ZoneTriac design in my own project?

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

Can I test firmware for the 8ZoneTriac 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.
