Dz TapeDelay Control: common questions
What microcontroller does the Dz TapeDelay Control use?
The Dz TapeDelay Control is built around the ATmega8-16P, from the AVR/Arduino family.
How big is the Dz TapeDelay Control PCB?
The Dz TapeDelay Control measures 106.7 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dz TapeDelay Control?
110 components, from 56 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dz TapeDelay Control design files?
From the dzavalishin/hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dz TapeDelay Control design in my own project?
The repository has no license, so all rights stay with dzavalishin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dz TapeDelay Control 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.
