SD Tape Player: common questions

What microcontroller does the SD Tape Player use?

The SD Tape Player is built around the Arduino_Nano_Socket, from the AVR/Arduino family.

How big is the SD Tape Player PCB?

The SD Tape Player measures 62.5 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SD Tape Player?

31 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the SD Tape Player design files?

From the GadgetReboot/SD_Tape_Player repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SD Tape Player design in my own project?

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

Can I test firmware for the SD Tape Player without the hardware?

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