Smu base: common questions

What microcontroller does the Smu base use?

The Smu base is built around the PIC24FJ128GC006-I_PT, from the PIC family.

How big is the Smu base PCB?

The Smu base measures 68.6 × 53.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Smu base?

92 components, from 47 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smu base design files?

From the bminch/smu_base repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Smu base design in my own project?

The repository has no license, so all rights stay with bminch. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Smu base 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.
