Abcdefg: common questions

What microcontroller does the Abcdefg use?

The Abcdefg is built around the Arduino_Nano_Socket, from the AVR/Arduino family.

How big is the Abcdefg PCB?

The Abcdefg measures 48.3 × 65.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Abcdefg?

29 components, from 14 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 Abcdefg design files?

From the ktoniman/Solar-Tracker repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Abcdefg design in my own project?

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

Can I test firmware for the Abcdefg 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.
