1808: common questions
What microcontroller does the 1808 use?
The 1808 is built around the Teensy_2.0++, from the NXP family.
How big is the 1808 PCB?
The 1808 measures 371.5 × 152.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 1808?
218 components, from 29 distinct parts. The full bill of materials is listed on this page.
Where can I download the 1808 design files?
From the se7en9057/1808 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the 1808 design in my own project?
Yes, under the terms of its GPL-3.0 license, which se7en9057 chose for the repository.
Can I test firmware for the 1808 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.
