SmartEffector: common questions

What microcontroller does the SmartEffector use?

The SmartEffector is built around the ATtiny44A-MMH-PAD, from the AVR/Arduino family.

How big is the SmartEffector PCB?

The SmartEffector measures 84.1 × 72.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SmartEffector?

45 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartEffector design files?

From the Duet3D/SmartEffector repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SmartEffector design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which Duet3D chose for the repository.

Can I test firmware for the SmartEffector 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.
