Atari 2600/7800 memory card (compatible with Atari 2600/7800 Save Key) tools.
Savekey plus test device is an open-source printed circuit board by JiggleSoft, from the JiggleSoft/atari-2600-memory-card-tool repository on GitHub. It is a 2-layer board of 116.8 × 63.5 mm with 15 parts on 10 nets, routed with 83 tracks and 48 vias.
It is built around the 24LC256-I/P. Its parts include 3 resistors, 2 capacitors, 2 ICs, 2 connectors and 1 diode. It belongs with the retro computing and games boards of this library.
This repository contains the design and implementation details of a USB interface and software management tool for Atari 2600/7800 memory cards, namely the SaveKey and SaveKey+.
The aim of this project is to provide the cheapest and simplest complete management solution for Atari 2600/7800 memory cards (SaveKey) devices.
I am currently awaiting delivery of Microchip PIC MCU and Microchip Serial EEPROM integrated circuits, but there is a long lead time. In the meantime work will proceed on soldering a USB Interface Tool development stripboard PCB and a savekey plus test device stripboard PCB. Then software development will continue.

It measures 116.8 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the 24LC256-I/P. 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 JiggleSoft/atari-2600-memory-card-tool repository on GitHub, at the commit this page was made from: the board is savekey-plus-test-device/hardware/kicad/savekey-plus-test-device/savekey-plus-test-device.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask JiggleSoft before reusing the design.
