Z80 YM2151: common questions

What microcontroller does the Z80 YM2151 use?

The Z80 YM2151 is built around the Arduino_1pin, from the AVR/Arduino family.

How big is the Z80 YM2151 PCB?

The Z80 YM2151 measures 100 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Z80 YM2151?

36 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Z80 YM2151 design files?

From the kuninet/Z80_YM2151 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Z80 YM2151 design in my own project?
