MAIN: common questions
What microcontroller does the MAIN use?
The MAIN is built around the DEV-15583, from the NXP family.
How big is the MAIN PCB?
The MAIN measures 119.7 × 117.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the MAIN?
35 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the MAIN design files?
From the MelissaKt/i-bots_soccer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MAIN design in my own project?
The repository has no license, so all rights stay with MelissaKt. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MAIN without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
