TR v0.1: common questions
What microcontroller does the TR v0.1 use?
The TR v0.1 is built around the ATmega328PB-AU, from the AVR/Arduino family.
How big is the TR v0.1 PCB?
The TR v0.1 measures 23.6 × 107 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TR v0.1?
50 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the TR v0.1 design files?
From the razvysme/Paisa-Soda repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the TR v0.1 design in my own project?
Yes, under the terms of its CC0-1.0 license, which razvysme chose for the repository.
Can I test firmware for the TR v0.1 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.
