Dso138-sub system: common questions

What microcontroller does the Dso138-sub system use?

The Dso138-sub system is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Dso138-sub system PCB?

The Dso138-sub system measures 163.5 × 85 mm, has 2 copper layers and is 1.599978 mm thick.

How many components are on the Dso138-sub system?

53 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dso138-sub system design files?

From the minfia/dso138-sub-system repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dso138-sub system design in my own project?

Yes, under the terms of its MIT license, which minfia chose for the repository.

Can I test firmware for the Dso138-sub system 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.
