NM27C512 Dumper: common questions

What microcontroller does the NM27C512 Dumper use?

The NM27C512 Dumper is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the NM27C512 Dumper PCB?

The NM27C512 Dumper measures 141.9 × 88.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NM27C512 Dumper?

130 components, from 64 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 NM27C512 Dumper design files?

From the IlyaBOT/LunarView3 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 NM27C512 Dumper design in my own project?

The repository has no license, so all rights stay with IlyaBOT. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the NM27C512 Dumper 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.
