LedMatrixDual: common questions

What microcontroller does the LedMatrixDual use?

The LedMatrixDual is built around the SAMD21E18A, from the Microchip SAM family.

How big is the LedMatrixDual PCB?

The LedMatrixDual measures 80 × 20 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LedMatrixDual?

27 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the LedMatrixDual design files?

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

Can I use the LedMatrixDual design in my own project?

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

Can I test firmware for the LedMatrixDual without the hardware?

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