Rti: common questions

What microcontroller does the Rti use?

The Rti is built around the ATMEGA328-PU, from the AVR/Arduino family.

How big is the Rti PCB?

The Rti measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rti?

54 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rti design files?

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

Can I use the Rti design in my own project?

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

Can I test firmware for the Rti 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.
