About the Tapeshnik proto PCB

Tapeshnik proto is an open source RP2040/RP2350 PCB design by svofski, published on GitHub. It is a 2-layer board measuring 84.3 × 64.5 mm, with 132 components from 54 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the 74HC14, 74HC4052D, LM358, AMS1117-5.0 and REF3030. By type, the board carries 65 resistors, 25 capacitors, 12 ICs, 10 connectors, 8 transistors and 8 diodes.

From the project

compact cassette data drive

Project goals. Not all of them are realistic.

utilize an existing consumer tape mechanism with "logic control" to make a fully automatic tape drive investigate the limits of what can be done with a simple compact cassette implement random access to sectors a usb mass storage device use a stereo track for double data rate access, eventually use a 4-track head for quad data rate investigate if altering motor speed to improve r/w speeds makes sense * investigate feasibility of reading while fast-forwarding with heads half-lifted

Tapeshnik proto: common questions

What microcontroller does the Tapeshnik proto use?

The Tapeshnik proto is built around the Pico, from the RP2040/RP2350 family.

How big is the Tapeshnik proto PCB?

The Tapeshnik proto measures 84.3 × 64.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tapeshnik proto?

132 components, from 54 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 Tapeshnik proto design files?

From the svofski/tapeshnik repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Tapeshnik proto design in my own project?

The repository has no license, so all rights stay with svofski. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Tapeshnik proto without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
