Oxidized flash: common questions
What microcontroller does the Oxidized flash use?
The Oxidized flash is built around the 497-1242-6, from the Microchip SAM family.
How big is the Oxidized flash PCB?
The Oxidized flash measures 61 × 21.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Oxidized flash?
19 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Oxidized flash design files?
From the blakesmith/embedded repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Oxidized flash design in my own project?
The repository has no license, so all rights stay with blakesmith. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Oxidized flash without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
