MotorFaderBoard: common questions

What microcontroller does the MotorFaderBoard use?

The MotorFaderBoard is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the MotorFaderBoard PCB?

The MotorFaderBoard measures 42 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MotorFaderBoard?

13 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the MotorFaderBoard design files?

From the 8-Lambda-8/ShowControllPCBs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MotorFaderBoard design in my own project?

Yes, under the terms of its GPL-3.0 license, which 8-Lambda-8 chose for the repository.

Can I test firmware for the MotorFaderBoard without the hardware?

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