40pin AVRMCU: common questions

What microcontroller does the 40pin AVRMCU use?

The 40pin AVRMCU is built around the ATMEGA32-P, from the AVR/Arduino family.

How big is the 40pin AVRMCU PCB?

The 40pin AVRMCU measures 40 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 40pin AVRMCU?

20 components, from 11 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 40pin AVRMCU design files?

From the ExploreEmbedded/ATmega32_ExploreUltraAvrDevKit repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 40pin AVRMCU design in my own project?

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

Can I test firmware for the 40pin AVRMCU 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.
