Schematic: common questions
What microcontroller does the Schematic use?
The Schematic is built around the DEV-16771, from the NXP family.
How big is the Schematic PCB?
The Schematic measures 83.5 × 57 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Schematic?
30 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Schematic design files?
From the RoboJackets/robowrestling repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Schematic design in my own project?
Yes, under the terms of its MIT license, which RoboJackets chose for the repository.
Can I test firmware for the Schematic 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.
