Iz1glg yaacw keyer: common questions

What microcontroller does the Iz1glg yaacw keyer use?

The Iz1glg yaacw keyer is built around the ATMEGA644P-P, from the AVR/Arduino family.

How big is the Iz1glg yaacw keyer PCB?

The Iz1glg yaacw keyer measures 110 × 92.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iz1glg yaacw keyer?

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

Where can I download the Iz1glg yaacw keyer design files?

From the federicobriata/iz1glg_yaacw_keyer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Iz1glg yaacw keyer design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which federicobriata chose for the repository.

Can I test firmware for the Iz1glg yaacw 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.
