Acoustic impact ball: common questions
What microcontroller does the Acoustic impact ball use?
The Acoustic impact ball is built around the ATSAMD21G18A-AU, from the Microchip SAM family.
How big is the Acoustic impact ball PCB?
The Acoustic impact ball measures 38 × 90 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Acoustic impact ball?
70 components, from 45 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 Acoustic impact ball design files?
From the akornsys-rdi/acoustic-impact-ball repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Acoustic impact ball design in my own project?
Yes, under the terms of its GPL-3.0 license, which akornsys-rdi chose for the repository.
Can I test firmware for the Acoustic impact ball without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
