Lights: common questions

What microcontroller does the Lights use?

The Lights is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Lights PCB?

The Lights measures 50 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lights?

115 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lights design files?

From the telec16/modular-synth repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lights design in my own project?

The repository has no license, so all rights stay with telec16. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Lights 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.
