Cw transceiver: common questions

What microcontroller does the Cw transceiver use?

The Cw transceiver is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How many components are on the Cw transceiver?

141 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cw transceiver design files?

From the Green-Avocado/cw-transceiver repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Cw transceiver design in my own project?

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

Can I test firmware for the Cw transceiver 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.
