Usb morse keyer: common questions

What microcontroller does the Usb morse keyer use?

The Usb morse keyer is built around the PIC16F886IP, from the PIC family.

How big is the Usb morse keyer PCB?

The Usb morse keyer measures 169.4 × 48.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb morse keyer?

79 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb morse keyer design files?

From the dilshan/usb-morse-keyer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Usb morse keyer design in my own project?

Yes, under the terms of its MIT license, which dilshan chose for the repository.

Can I test firmware for the Usb morse keyer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
