About the PlipUltimate PCB

PlipUltimate is an open source AVR/Arduino PCB design by tehKaiN, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 50 × 50 mm, with 51 components from 32 distinct parts.

Its main chip is the ATMEGA328P, from the AVR/Arduino family. Other key parts include the ENC28J60, LM2596_5.0, 74LVC125, IRF7309 and AMS1117_3V3. By type, the board carries 18 capacitors, 14 resistors, 7 ICs, 5 connectors, 3 diodes and 2 inductors.

It belongs with the retro computing designs in this gallery.

From the project

Network interface & SD card reader for Classic Amigas

Released under the GNU Public License V2 (see LICENSE and AUTHORS for details).

Currently IP traffic is done in bridge mode - packets are generated by Amiga's network stack and sent to interface using PLIP protocol. Since AVR CPU may run as fast as 20MHz, there is a room for improvement by moving generic packet generation to AVR. SD card reader support is yet to be added.

PlipUltimate: common questions

What microcontroller does the PlipUltimate use?

The PlipUltimate is built around the ATMEGA328P, from the AVR/Arduino family.

How big is the PlipUltimate PCB?

The PlipUltimate measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PlipUltimate?

51 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the PlipUltimate design files?

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

Can I use the PlipUltimate design in my own project?

Yes, under the terms of its GPL-2.0 license, which tehKaiN chose for the repository.

Can I test firmware for the PlipUltimate 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.
