Protocol Analyzer: common questions
What microcontroller does the Protocol Analyzer use?
The Protocol Analyzer is built around the STM32F030K6Tx, from the STM32 family.
How big is the Protocol Analyzer PCB?
The Protocol Analyzer measures 66 × 45.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Protocol Analyzer?
31 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Protocol Analyzer design files?
From the Sidharth-Saji/Protocol_Analyzer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Protocol Analyzer design in my own project?
The repository has no license, so all rights stay with Sidharth-Saji. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Protocol Analyzer 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.
