4 ATA/ATAPI IDE Interface for Commodore Amiga 1200 and Amiga 600 computers
4IDEAdapter is an open-source printed circuit board by gianlucarenzi, from the gianlucarenzi/4IDEAdapter repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 76 × 100 mm with 18 parts on 50 nets, routed with 812 tracks and 41 vias.
It is built around the 74LVC2G08. Its parts include 3 resistors, 3 diodes and 1 IC. It belongs with the retro computing and games boards of this library.

It is a simple but powerful adapter to use internally in any Amiga 1200 or Amiga 600 Computer installed in a tower-like case! It must be connected to the IDE 44-pin interface on the motherboard to drive up to 4 ATA/ATAPI devices like Hard Drives, DVD Rom Drives and compatible drives.
This project follow the same DIY project in Aminet (search 4IDE in docs/hw) or simply check out here:
This board has three indipendent activity leds, one for each channel. Moreover the activity leds are merged together in the motherboard so the HDD led nearby the floppy connector can be used as the only activity led.
May be it can be useful to add a 90-degrees rise connector if the system has some sort of bus board, just to let this board flat as the motherboard.

A RoboRIO-Inspired Expansion board for Robotics. Mostly for funsies + learning.

It measures 76 × 100 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the 74LVC2G08. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the gianlucarenzi/4IDEAdapter repository on GitHub, at the commit this page was made from: the board is 4IDEAdapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
