OpenLST: common questions
What microcontroller does the OpenLST use?
The OpenLST is built around the 64 LQFP STM32L496RGT6TR, from the STM32 family.
How big is the OpenLST PCB?
The OpenLST measures 80 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the OpenLST?
171 components, from 84 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 OpenLST design files?
From the MatthiasGeorgImhof/Hardware_CSAT 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 OpenLST design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the OpenLST 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.
