Titan R3: common questions
What microcontroller does the Titan R3 use?
The Titan R3 is built around the ATSAMD51J19A-A, from the Microchip SAM family.
How big is the Titan R3 PCB?
The Titan R3 measures 40 × 80 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Titan R3?
91 components, from 61 distinct parts. The full bill of materials is listed on this page.
Where can I download the Titan R3 design files?
From the 1337bowen/Strife repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Titan R3 design in my own project?
Yes, under the terms of its MIT license, which 1337bowen chose for the repository.
Can I test firmware for the Titan R3 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
