6502 DEV Output Board: common questions
What microcontroller does the 6502 DEV Output Board use?
The 6502 DEV Output Board is built around the SN74LVC4245APWR, from the NXP family.
How big is the 6502 DEV Output Board?
The 6502 DEV Output Board measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 6502 DEV Output Board?
7 components, from 7 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 6502 DEV Output Board design files?
From the acwright/6502-DEV repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the 6502 DEV Output Board design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which acwright chose for the repository.
Can I test firmware for the 6502 DEV Output Board 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.
