Dino serial
About the Dino serial PCB
Dino serial is an open source PCB design by robertrico, published on GitHub. It is a 2-layer board measuring 40.7 × 35.8 mm, with 8 components from 6 distinct parts.
Other key parts include the 74LS138, 74LS245 and 16550. By type, the board carries 3 ICs, 3 capacitors, 1 crystal and 1 connector.
From the project
Discrete Integrated NISC Operator — an 8-bit CPU built from 74-series logic on breadboards. That's the machine itself: no microcontroller, no FPGA. Every register, every bus, every gate is a chip you can put a probe on. (The repo does carry a generated FPGA twin for design-ahead

Schematics in KiCad, microcode in EEPROM, and a bare-metal ATmega2560 test rig that brings the machine up one board at a time.

Dino serial: common questions
How big is the Dino serial PCB?
The Dino serial measures 40.7 × 35.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dino serial?
8 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dino serial design files?
From the robertrico/dino-homebrew 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 serial design in my own project?
The repository has no license, so all rights stay with robertrico. Use it as a reference, and ask the author before reusing the design.
