SignalGenerator: common questions

What microcontroller does the SignalGenerator use?

The SignalGenerator is built around the ATMEGA328-A, from the AVR/Arduino family.

How big is the SignalGenerator PCB?

The SignalGenerator measures 99.8 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SignalGenerator?

115 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the SignalGenerator design files?

From the ukmaker/SignalGenerator repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SignalGenerator design in my own project?

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

Can I test firmware for the SignalGenerator 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.
