Transmitter: common questions

What microcontroller does the Transmitter use?

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

How big is the Transmitter PCB?

The Transmitter measures 63 × 40.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Transmitter?

37 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Transmitter design files?

From the damianmoore/audio-lighting-broadcast repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Transmitter design in my own project?

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

Can I test firmware for the Transmitter 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.
