Torchic: common questions
What microcontroller does the Torchic use?
The Torchic is built around the ATmega16M1-AU, from the AVR/Arduino family.
How big is the Torchic PCB?
The Torchic measures 42.2 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Torchic?
21 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Torchic design files?
From the lindamao-waterloop/waterloop_electrical repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Torchic design in my own project?
The repository has no license, so all rights stay with lindamao-waterloop. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Torchic 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.
