Slice RTDM: common questions

What microcontroller does the Slice RTDM use?

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

How big is the Slice RTDM PCB?

The Slice RTDM measures 70 × 100 mm, has 2 copper layers and is 1.67 mm thick.

How many components are on the Slice RTDM?

44 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Slice RTDM design files?

From the feastorg/Slice_RTDM repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Slice RTDM design in my own project?

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

Can I test firmware for the Slice RTDM 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.
