K3ng w0odj keyer: common questions

What microcontroller does the K3ng w0odj keyer use?

The K3ng w0odj keyer is built around the Arduino_Mega2560_Shield, from the AVR/Arduino family.

How big is the K3ng w0odj keyer PCB?

The K3ng w0odj keyer measures 100 × 92 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the K3ng w0odj keyer?

38 components, from 22 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 K3ng w0odj keyer design files?

From the kawfey/k3ng_w0odj_keyer-PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the K3ng w0odj keyer design in my own project?

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

Can I test firmware for the K3ng w0odj keyer 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.
