SSS: common questions
What microcontroller does the SSS use?
The SSS is built around the PIC16F876A, from the PIC family.
How big is the SSS PCB?
The SSS measures 98.8 × 60.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SSS?
69 components, from 37 distinct parts. The full bill of materials is listed on this page.
Where can I download the SSS design files?
From the wonbinbk/SSS repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the SSS design in my own project?
Yes, under the terms of its GPL-3.0 license, which wonbinbk chose for the repository.
Can I test firmware for the SSS 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.
