Slim: common questions

What microcontroller does the Slim use?

The Slim is built around the ATtiny1604-SS, from the AVR/Arduino family.

How big is the Slim PCB?

The Slim measures 44 × 44 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Slim?

64 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Slim design files?

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

Can I use the Slim design in my own project?

Yes, under the terms of its MIT license, which McbeEringi chose for the repository.

Can I test firmware for the Slim 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.
