Mss cascade basic: common questions
What microcontroller does the Mss cascade basic use?
The Mss cascade basic is built around the ATtiny861A-S, from the AVR/Arduino family.
How big is the Mss cascade basic PCB?
The Mss cascade basic measures 82.6 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mss cascade basic?
85 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mss cascade basic design files?
From the IowaScaledEngineering/mss-cascade repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mss cascade basic design in my own project?
The repository has no license, so all rights stay with IowaScaledEngineering. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mss cascade basic 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.
