Halakekit first break: common questions
What microcontroller does the Halakekit first break use?
The Halakekit first break is built around the Arduino_Pro_Micro, from the AVR/Arduino family.
How big is the Halakekit first break PCB?
The Halakekit first break measures 2.8 × 2.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Halakekit first break?
22 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Halakekit first break design files?
From the asukiaaa/halakekit_first_break repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Halakekit first break design in my own project?
The repository has no license, so all rights stay with asukiaaa. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Halakekit first break 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.
