Q-Chord Multicart
About the Q-Chord Multicart PCB
Q-Chord Multicart is an open source PCB design by partlyhuman, published on GitHub under the MIT license. It is a 2-layer board measuring 55 × 54.5 mm, with 12 components from 8 distinct parts.
Other key parts include the MX29LV640EBTI-70G and MIC5365-3.3YD5. By type, the board carries 5 resistors, 3 capacitors, 2 ICs, 1 connector and 1 switch.
From the project
Hardware and Software for the Suzuki Q-Chord
Things that work with the Suzuki QChord, primarily a reproduction QCard that can be built with completely off-the-shelf parts. These projects are under active development.
You can get one as long as stock lasts at my Ko-Fi shop!
A single cartridge that contains the entire Q-Card library, selectable by dip switches. The flash should be programmed prior to assembly, by concatenating the 4Mbit dumps you can find on archive.org.
