DuPal DIP: common questions

What microcontroller does the DuPal DIP use?

The DuPal DIP is built around the ATmega8A-PU, from the AVR/Arduino family.

How big is the DuPal DIP PCB?

The DuPal DIP measures 113 × 78.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DuPal DIP?

50 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the DuPal DIP design files?

From the DuPAL-PAL-DUmper/DuPAL_Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DuPal DIP design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which DuPAL-PAL-DUmper chose for the repository.

Can I test firmware for the DuPal DIP 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.
