Power board: common questions
What microcontroller does the Power board use?
The Power board is built around the ATmega328P-AU, from the AVR/Arduino family.
How big is the Power board?
The Power board measures 171.8 × 117.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Power board?
80 components, from 49 distinct parts. The full bill of materials is listed on this page.
Where can I download the Power board design files?
From the MST-Robotics/TITAN-Electrical repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Power board design in my own project?
The repository has no license, so all rights stay with MST-Robotics. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Power board 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.
