Duotape
About the Duotape PCB
Duotape is an open source PCB design by ikorb, published on GitHub. It is a 2-layer board measuring 27.5 × 45.8 mm, with 9 components from 8 distinct parts.
Other key parts include the 74HC4053. By type, the board carries 3 connectors, 3 resistors, 1 IC, 1 switch and 1 capacitor.
It belongs with the retro computing designs in this gallery.

a tape port storage pod for the C64
This directory contains KiCAD schematics and layout for three different implementations of the tapecart:
This version of the tapecart is optimized for DIY builders - it does not require any SMD components. Since DIP versions of the flash chips are a bit hard to source, it has an alternate footprint for using an SMD flash chip instead. The firmware for this version must be compiled using the config file "config-diy". A precompiled hex file is located in the subdirectory "firmware".

Duotape: common questions
How big is the Duotape PCB?
The Duotape measures 27.5 × 45.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Duotape?
9 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Duotape design files?
From the ikorb/tapecart repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Duotape design in my own project?
The repository has no license, so all rights stay with ikorb. Use it as a reference, and ask the author before reusing the design.
