Peripheral board: common questions
What microcontroller does the Peripheral board use?
The Peripheral board is built around the ATMEGA4809-PF, from the AVR/Arduino family.
How big is the Peripheral board?
The Peripheral board measures 165 × 135 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Peripheral board?
145 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the Peripheral board design files?
From the Lintaroh/OMA68k repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Peripheral board design in my own project?
Yes, under the terms of its MIT license, which Lintaroh chose for the repository.
Can I test firmware for the Peripheral 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.
