LB-100: common questions
What microcontroller does the LB-100 use?
The LB-100 is built around the LM74930QRGERQ1, from the STM32 family.
How big is the LB-100 PCB?
The LB-100 measures 100 × 70 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the LB-100?
99 components, from 68 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LB-100 design files?
From the avlyubimov/svc-platform repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the LB-100 design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the LB-100 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.
