Ipd sem3: common questions

What microcontroller does the Ipd sem3 use?

The Ipd sem3 is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Ipd sem3 PCB?

The Ipd sem3 measures 120 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ipd sem3?

1 components, from 1 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 Ipd sem3 design files?

From the malharshah04/ipd-sem3 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ipd sem3 design in my own project?

The repository has no license, so all rights stay with malharshah04. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ipd sem3 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.
