Service Section Controller: common questions
What microcontroller does the Service Section Controller use?
The Service Section Controller is built around the ATMEGA16M1-AU-ND, from the AVR/Arduino family.
How big is the Service Section Controller PCB?
The Service Section Controller measures 158.8 × 158.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Service Section Controller?
223 components, from 83 distinct parts. The full bill of materials is listed on this page.
Where can I download the Service Section Controller design files?
From the olin-electric-motorsports/olin-electric-motorsports repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Service Section Controller design in my own project?
The repository has no license, so all rights stay with olin-electric-motorsports. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Service Section Controller 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.
