Dino z80: common questions
What microcontroller does the Dino z80 use?
The Dino z80 is built around the RP2350B, from the RP2040/RP2350 family.
How big is the Dino z80 PCB?
The Dino z80 measures 99.5 × 80 mm, has 4 copper layers and is 1 mm thick.
How many components are on the Dino z80?
258 components, from 93 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dino z80 design files?
From the rh1tech/frank-lab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dino z80 design in my own project?
Yes, under the terms of its GPL-3.0 license, which rh1tech chose for the repository.
Can I test firmware for the Dino z80 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
