BRICOLEUR: common questions

What microcontroller does the BRICOLEUR use?

The BRICOLEUR is built around the EFM32GG980, from the Silicon Labs family.

How big is the BRICOLEUR PCB?

The BRICOLEUR measures 124.5 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BRICOLEUR?

78 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the BRICOLEUR design files?

From the NTNU-TDT4295/BRICOLEUR repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the BRICOLEUR design in my own project?

The repository has no license, so all rights stay with NTNU-TDT4295. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the BRICOLEUR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
