About the QSC-RW PCB
QSC-RW is an open source PCB design by partlyhuman, published on GitHub under the MIT license. It is a 4-layer board measuring 55 × 33.1 mm, with 4 components from 4 distinct parts.
Other key parts include the SST39SF040. By type, the board carries 1 IC, 1 connector, 1 capacitor and 1 resistor.
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.
