Sss opr3-v1 (1): common questions

What microcontroller does the Sss opr3-v1 (1) use?

The Sss opr3-v1 (1) is built around the STM32L476ZGTx, from the STM32 family.

How big is the Sss opr3-v1 (1) PCB?

The Sss opr3-v1 (1) measures 90 × 90 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Sss opr3-v1 (1)?

267 components, from 78 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sss opr3-v1 (1) design files?

From the Space-and-Satellite-Systems-UC-Davis/PCBs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Sss opr3-v1 (1) design in my own project?

The repository has no license, so all rights stay with Space-and-Satellite-Systems-UC-Davis. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sss opr3-v1 (1) without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
